Optimization and innovation of gold extraction process from gold mines
一  Differentiated Design and Technology Selection for CIL and CIP Processes Although both CIL (carbon-in-leach) and CIP (carbon-in-pulp) processes are activated carbon adsorption gold extraction processes, they differ significantly in process design, operational logic, and applicable scenarios:  Differentiating Mechanisms: CIL simultaneously reduces the liquid gold concentration through leaching and adsorption, driving the cyanidation reaction kinetics. CIP optimizes leaching and adsorption conditions step by step to reduce impurity interference, but the process is more complex. 二  Key Influences of Activated Carbon Adsorption Kinetics on Gold Recovery The adsorption efficiency of activated carbon for gold-cyanide complex (Au(CN)₂⁻) is determined by both pore structure and chemical modification. The key parameters are as follows: 1. Adsorption Kinetic Model Diffusion-controlled Stage: Au(CN)₂⁻ migrates to adsorption sites through micropores (1000 m²/g). Chemical Adsorption Stage: Oxygen-containing functional groups (such as carboxyl and phenolic hydroxyl groups) on the activated carbon surface coordinate with Au(CN)₂⁻, with an apparent activation energy of 15-18 kJ/mol (laboratory measured values). 2. Optimized Parameters Pore Structure: Coconut shell charcoal with a micropore ratio >70% has a gold adsorption capacity of 6-8 kg Au/t charcoal; fruit shell charcoal with a micropore ratio 5 g/t), modified coconut shell charcoal with a K value ≥30 is recommended. The gold concentration in the tailings can be controlled at 0.05-0.1 mg/L. 三  Pretreatment Technology for Arsenic-Containing Gold Ore and Efficiency Improvement Mechanism Arsenic compounds (such as FeAsS) encapsulating gold particles is the primary cause of low leaching yields. Pretreatment technologies release gold through mineral dissociation: 1. Roasting Oxidation Method Process Parameters: Two-stage roasting (first stage at 650°C to remove arsenic and produce As₂O₃ gas, second stage at 800°C to remove sulfur and produce porous Fe₂O₃ roasted sand). Verification: After roasting a high-arsenic ore (12% As content), the gold leaching rate increased from 41% to 90.5%, but a flue gas purification system (As₂O₃ capture efficiency >99%) was required. 2. Pressurized Oxidation Method Acidic Oxidation: Under conditions of 190°C and 2.0 MPa, arsenopyrite decomposes into Fe₃⁺ and SO₄²⁻, converting arsenic into H₃AsO₃, increasing the gold leaching rate to 88%-95%. Limitations: Titanium reactors cost $30 million per 10,000 tons of production capacity, making them suitable only for large-scale mines. 3. Biooxidation Method Microbial Action: Acidithiobacillus ferrooxidans catalyzes the conversion of Fe²⁺ to Fe³⁺, dissolving the arsenopyrite coating and achieving an arsenic removal rate of >90%. Efficiency Improvement: Biooxidation of a difficult-to-treat gold ore (2.5 g/t Au, 8% As) increased the cyanide leaching rate from 25% to 92%, and the oxidation cycle was optimized to 7 days (with the addition of an Fe³⁺ catalyst). 四  Large-Scale Application and Technological Breakthroughs in Biooxidation Pretreatment Due to its environmental advantages, biooxidation technology has achieved commercial application in specific scenarios: 1. Applicable Limits Ore Type: Sulfide-encapsulated gold ore (As 1%-15%), mineral dissociation degree 99% (producing scorodite FeAsO₄·2H₂O). A large mine in Peru: Daily processing of 2,000 tons of ore containing 20% ​​arsenic, achieving a slag cyanide recovery rate >90%, and a 30% reduction in overall costs compared to roasting. 3. Technical Bottlenecks and Breakthroughs Bacterial Acclimation: Arsenic-tolerant strains (such as Leptospirillum ferriphilum) can survive at As₃⁺ concentrations of 15 g/L, increasing oxidation rates by 25%.  Process Coupling: The combined biooxidation + CIL process can process ultra-low-grade ores (Au 0.8 g/t), achieving an overall recovery rate exceeding 85%.
Mineral processing professionals must know: 5 most basic mineral processing methods, the principles are easy to understa
For every practitioner or student in the mineral processing field, a deep understanding and mastery of basic mineral processing methods is the golden key to unlocking the door to professional expertise. The separation of useful minerals from gangue minerals in ore is a critical step in the entire mineral resource development and utilization process. The purpose of mineral processing is to enrich useful minerals through various methods, remove harmful impurities, and provide qualified raw materials for subsequent smelting or industrial applications. This article systematically reviews and deeply analyzes five of the most basic and widely used mineral processing methods, aiming to help readers build a clear knowledge framework, ensuring a clear understanding of the principles and straightforward application. These five core methods are:       Gravity Separation       Flotation       Magnetic Separation       Electrostatic Separation       Chemical Processing (Hydrometallurgy) 01 Gravity Separation  Gravity separation (abbreviated as gravity separation) is one of the oldest mineral processing technologies, with its application dating back thousands of years to gold mining. Today, gravity separation remains important in the processing of tungsten, tin, gold, iron ore, and coal, due to its low cost, minimal environmental impact, and high processing capacity. Core Principle: Gravity separation is fundamentally based on the density differences between minerals. When mineral particles are in a moving medium (primarily water or air), they are subject to the combined effects of gravity, fluid dynamics, and other mechanical forces. High-density particles settle quickly and settle in the lower layers of the equipment, while low-density particles settle slowly and settle in the upper layers. Specific equipment and process flows can separate these two density groups. Particle size and shape also influence the separation process, so strict particle size control of the incoming material is often required in practice. Applicable conditions: There is a significant density difference between minerals, which is the prerequisite for the effective operation of gravity separation. It can handle a wide range of particle sizes and is particularly good at processing coarse-grained ores that are difficult to process with other methods.   It is suitable for processing gold and tin, wolframite, hematite and coal. Main equipment: Jig: It loosens the bed layer and separates it into layers according to density through periodic vertical alternating water flow. It is commonly used to process coarse and medium-sized ores and coal.  Shaking table: On an inclined bed, it utilizes the differential reciprocating motion of water flow and bed surface to loosen and separate the ore particles into layers and perform zonal separation. It is suitable for the separation of fine-grained ores. Spiral chute/spiral concentrator: It utilizes the combined effects of gravity, centrifugal force and water flow to separate the ore slurry as it flows in the spiral trough. It is suitable for processing fine-grained materials with a particle size of 0.03mm to 0.6mm.   Heavy medium separator: It uses a heavy suspension with a density between useful minerals and gangue as the separation medium. Ore particles with a density less than the medium float up, while those with a density greater than the medium sink, achieving precise separation. 02 Flotation Flotation is one of the most widely used mineral processing methods, particularly in the processing of non-ferrous metals (copper, lead, zinc), precious metals (gold, silver), and various non-metallic ores. Core Principles: Flotation exploits differences in the physical and chemical properties of mineral surfaces—namely, their varying floatability (hydrophobicity). By adding a series of specific flotation agents to a fully ground slurry, these surface properties can be artificially altered. 1. Regulators adjust the slurry's pH, among other factors, to create an optimal environment for other agents to function. 2. Collectors selectively adsorb onto the target mineral surface, rendering it hydrophobic (non-wettable by water). 3. Frothers reduce the surface tension of water, generating a large number of stable bubbles of optimal size. After treatment with the reagent, the hydrophobic target mineral particles selectively adhere to the bubbles and float to the surface of the slurry, forming a mineralized foam layer. The hydrophilic gangue minerals, on the other hand, remain in the slurry. The foam is scraped off with a scraper to obtain the enriched concentrate. Applicable conditions: Suitable for processing various sulfide ores with fine particle size and complex composition, such as copper, lead, zinc, nickel, molybdenum and other ores.  Widely used in the separation of oxide ores, non-metallic ores (such as fluorite, apatite) and precious metal ores. Flotation is an extremely effective method for separating minerals with similar density and no obvious difference in magnetic and electrical properties. Key elements (reagent system): The effectiveness of flotation depends heavily on the correct reagent system, including reagent type, dosage, order of addition, and location. Collectors: These agents, such as xanthates and nitroglycerins, are key to achieving hydrophobicity.  Frothers: These agents, such as pine oil (No. 2 oil), are responsible for creating stable foam.  Adjusters: These agents include activators (such as copper sulfate), inhibitors (such as lime and cyanide), and pH adjusters, used to enhance or diminish the floatability of minerals and improve separation selectivity. 03 Magnetic Separation Magnetic separation is a physical method that uses the magnetic difference of minerals for sorting. The process is simple and usually does not cause environmental pollution. It plays an indispensable role in the selection of ferrous metal ores (especially iron ore). It is also widely used to remove iron-containing impurities or recover magnetic substances from other minerals. Core principle: When ore particles pass through the uneven magnetic field generated by the magnetic separator, ore particles with different magnetic properties will be subject to magnetic forces of different magnitudes.  Strongly magnetic minerals (such as magnetite) will be attracted by the strong magnetic force and adsorbed to the surface of the magnetic pole (such as the magnetic drum). With the movement of the magnetic pole, they are taken to the designated position, leave the magnetic field and fall to become concentrates.  Non-magnetic or weakly magnetic minerals (such as quartz and some gangue) are subject to little or almost no magnetic force. Under the action of gravity and centrifugal force, they move along the original path and become tailings. Applicable conditions: Magnetite sorting: Magnetic separation is the most important and efficient method for processing magnetite. Sorting other magnetic minerals: It can also be used to sort manganese ore, chromite, ilmenite and some rare metal minerals with weak magnetism (such as wolframite). Iron removal: In the purification of non-metallic mineral raw materials such as ceramics and glass, it is used to remove harmful iron impurities to improve the whiteness of the product. Heavy medium recovery: In heavy medium coal or ore dressing, it is used to recover magnetic heavy materials such as magnetite powder. Main equipment: There are many types of magnetic separators. According to the magnetic field strength, they can be divided into weak magnetic field, medium magnetic field and strong magnetic field magnetic separators; according to the equipment structure, they can be divided into drum type, roller type, disc type and magnetic separation column type. Permanent magnet drum magnetic separator: The most widely used, often used to process strongly magnetic magnetite, and divided into co-current, counter-current and semi-counter-current types according to the slurry flow direction.  High gradient magnetic separator: It can generate a strong magnetic field gradient, which is used to sort weakly magnetic minerals or remove fine-grained iron impurities. • Magnetic pulley/magnetic drum: Commonly used for dry pre-selection to remove large iron pieces before the material enters the crusher to protect the equipment. 04 Electric separation Electrostatic separation utilizes differences in the conductive properties of minerals to separate them in a high-voltage electric field. This dry separation method is particularly suitable for water-scarce areas. While not as widely used as the previous three methods, it plays an irreplaceable role in separating certain mineral combinations, such as scheelite from cassiterite and zircon from rutile.  Core Principle: The electrostatic separation process primarily involves two steps: charging and separation.When preheated and dried mineral particles enter the high-voltage electric field formed by corona electrodes and rotating rollers:  Conductive minerals (such as ilmenite and cassiterite) quickly acquire an electric charge and rapidly dissipate it due to contact with the grounded rollers. After losing their charge, they are thrown from the rollers by centrifugal force and gravity.  Non-conductive minerals (such as zircon and quartz) have poor conductivity and are difficult to dissipate after acquiring an electric charge. They are attracted to the roller surface by electrostatic forces, moving to the rear of the roller as the roller rotates, and then being swept away by brushes.Since the two minerals have significantly different motion paths, separation is achieved.  Applicable Conditions: There must be significant differences in electrical conductivity between minerals. Common conductive minerals include magnetite, ilmenite, cassiterite, etc.; non-conductive minerals include quartz, zircon, feldspar, scheelite, etc.  Commonly used in the selection of non-ferrous metals, ferrous metals and rare metal ores, especially for separating associated minerals from mixed concentrates of gravity separation or magnetic separation.  The materials to be selected must be strictly dry, clean and of uniform particle size.  Main equipment:  Roller electrostatic separator: It is the most commonly used electrostatic separation equipment, which consists of a rotating grounded roller and a high-voltage corona electrode to form a working area. Plate/screen plate electrostatic separator: It is used to process materials with different particle size ranges. 05 Chemical Ore Dressing / Hydrometallurgy Chemical ore dressing, often closely associated with the concept of hydrometallurgy, utilizes chemical reactions to alter the physical phases of mineral components, thereby separating useful components from impurities. This method is particularly suitable for processing low-grade, complex, and finely impregnated ores, such as copper oxide, gold, and uranium ores, which are difficult to separate using traditional physical separation methods.  Core Principle:  Its core is selective leaching. Using a specific chemical solvent (leachant), under specific temperature and pressure conditions, the target metal or its compounds in the ore are selectively dissolved into a solution, while the gangue minerals remain in the solid phase (leaching residue). The main steps include:       1. Leaching: The ore is treated with a leaching agent such as an acid (such as sulfuric acid), an alkali (such as sodium hydroxide), or a salt solution (such as cyanide) to release the useful metal into the liquid phase.        2. Liquid-Solid Separation: The target metal-rich solution (leachate) is separated from the leaching residue.       3. Solution purification and enrichment: Use precipitation, solvent extraction or ion exchange to remove impurity ions in the solution and increase the concentration of the target metal.       4. Metal recovery: Extract the final metal product or its compound from the purified solution through electrolysis, displacement or precipitation. Applicable conditions: Processing of low-grade oxide ores: For example, the acid leaching-extraction-electrolysis process for low-grade copper oxide ores.  Extraction of precious metals: For example, the cyanide leaching method for gold ores is the most widely used gold extraction process.  Processing of complex and difficult-to-separate ores: For ores with similar physical properties and complex interbedded relationships, chemical beneficiation is often the only effective way.  Metal recovery from waste: It has broad prospects in areas such as battery recycling and electronic waste treatment.  Typical processes: Cyanide gold extraction: Use sodium cyanide solution to dissolve the gold in the ore, and then replace the gold with zinc powder. Acid leaching of copper: Leach the copper oxide ore with dilute sulfuric acid to obtain a copper sulfate solution, which is then extracted and electrolyzed to obtain high-purity cathode copper.   Bayer process for producing alumina: Treating bauxite with sodium hydroxide solution under heated and pressurized conditions is a classic hydrometallurgical process for producing alumina. The five fundamental methods of mineral separation—gravity separation, flotation, magnetic separation, electrostatic separation, and chemical separation—form the cornerstone of modern mineral processing technology. Each method has its own unique scientific principles and scope of application. In actual production, mineral processing engineers often need to flexibly select a single method or combine multiple methods based on the specific properties of the ore (such as mineral composition, dissemination characteristics, and physical and chemical properties), technical and economic indicators, and environmental protection requirements to develop the optimal mineral processing process, thereby achieving efficient, economical, and green development of mineral resources. A deep understanding and mastery of these fundamental principles is fundamental for every mineral processing engineer to solve practical problems and promote technological innovation.
Australia's Gold Output Reaches 300 Tonnes Again
According to Mining Weekly, data from Melbourne-based consulting firm Surbiton Associates (SA) shows that Australia’s mine gold production for the 2024/25 financial year reached 300 tonnes, hitting a two-year high, though still below the record 328 tonnes achieved in the 1999/2000 financial year.   In the second quarter of 2025, production reached 76 tonnes, a quarter-on-quarter increase of 3 tonnes, or 4%, reflecting steady growth in the industry. At a gold price of A$5,200 per ounce, the annual output value slightly exceeded A$50 billion, making gold Australia’s fourth-largest export commodity, behind iron ore, coal, and liquefied natural gas.   "Australia’s gold mining industry is efficient, highly productive, and critically important," said Dr. Sandra Close, Director of SA. "Gold exports are worth almost half the combined export value of Australia’s agricultural, forestry, and fishery products. Unfortunately, this is poorly understood by many politicians and most of the public."   Global uncertainties, including tensions in the Middle East and the Russia-Ukraine conflict, as well as the radical policies of U.S. President Trump, have continued to drive up the U.S. dollar-denominated gold price. This has led to an even larger increase in the Australian dollar gold price, despite the strength of the Australian dollar.   The practice of blending stockpiled low-grade ore with newly mined ore has somewhat restrained production growth, with this ratio just exceeding 15% in the second quarter. This approach helps extend mine life and optimizes resource utilization.   Foreign control over Australia’s gold mines has varied over time. In 1997, foreign companies controlled 20% of Australia’s gold production, peaking at 70% by the end of 2002. Currently, foreign control stands at approximately 45%. This proportion is expected to rise following the completion of South African Gold Fields’ A$3.7 billion acquisition of Gold Road Resources in late September.   This acquisition involves the Gruyere gold mine, located 200 kilometers east of Laverton, which was discovered by Gold Road in 2013. Gold Fields acquired a 50% stake in the mine in 2016 for A$350 million. Mine construction was completed in 2019 at a cost of A$621 million, with production for the 2024/25 financial year reaching 305,000 ounces. The open pit is expected to reach a depth of at least 500 meters, making it one of Australia’s deepest open-pit mines.   "Although Australian entities control 55% of gold mines overall, their ownership of the top five gold mines in the 2024/25 financial year was only 24%," Close noted. "This truly highlights the dominance of overseas companies over our largest gold producers."   In the 2024/25 financial year, Australia’s top gold mine was Newmont’s Boddington, with production of 574,000 ounces. It was followed by the Tropicana mine (AngloGold Ashanti 70%, Regis Resources 30%) with 466,100 ounces, Newmont’s Cadia mine with 432,000 ounces, Northern Star’s Super Pit with 405,400 ounces, and Newmont’s Tanami mine with 387,000 ounces.   In the second quarter, Boddington remained Australia’s largest gold-producing mine, with output of 147,000 ounces. It was followed by the Super Pit (117,400 ounces), Cadia (104,000 ounces), Gold Fields’ St Ives (99,200 ounces), and Tropicana (93,800 ounces).     Article Source: https://geoglobal.mnr.gov.cn/zx/kydt/zhyw/202509/t20250902_9974529.htm

Russia to Increase Production of "Three Rare" Metals
According to MiningNews.net, the Russian Ministry of Industry and Trade announced on August 12 that, in accordance with the industrial development plan adopted in March, Russia aims to increase its annual production of "Large-tonnage rare metals" (LARM) to 50,000 tons by 2030.   LARM is a term used by Russia to describe various critical minerals, including lithium, tungsten, molybdenum, niobium, and zirconium.   The Russian Ministry of Industry and Trade stated that the government’s so-called "Low-tonnage rare metals" (LORM) include tantalum, beryllium, germanium, gallium, and hafnium, with a target production of 80 tons by 2030. In 2024, Russia hardly produces these minerals.   Under this plan, the Russian government aims to build domestic processing capacity to produce refined products for the domestic market.   On July 2, Russian Minister of Industry and Trade Anton Alikhanov announced at a meeting of the Federation Council of the Parliament that the government is collaborating with investors to promote 20 projects in the field of critical minerals and rare earth metals.   The ministry is screening projects eligible for state support, including direct subsidies for research and development activities, low-interest soft loans, and reduced import and export tariffs. According to the industrial development plan, Russia intends to allocate 60 billion rubles ($744 million) from the federal budget to support several projects in this sector. Currently, there is no consensus on the scale or feasibility standards of Russia’s critical mineral deposits.   In 2024, the Russian Federal Subsoil Resources Management Agency (Rosnedra) estimated that the country’s reserves of critical minerals and rare earth metals amount to approximately 28.8 million tons, ranking second in the world.   However, the U.S. Geological Survey (USGS) estimated that Russia’s rare earth mineral reserves in 2023 were only 1 million tons, ranking fourth after China, Vietnam, and Brazil.   In recent years, all rare earth projects approved in Russia have stalled, as most deposits are unprofitable to mine at current market prices.   For example, the Russian state-owned enterprise Rostec and its partners won a bid in 2014 for the Tomtorskoye project in Yakutia, northern Siberia. The project is considered one of the world’s largest rare earth deposits, with reserves of nearly 3.2 million tons, and was originally scheduled to commence production in 2019 or 2020.   However, Rostec withdrew from the project in 2019, and its future has remained uncertain ever since.   Another attempt to start rare earth production in Russia was made by fertilizer manufacturer Acron Group, which began extracting rare earth metal oxides from apatite-nepheline ore in the Murmansk region in 2016. This investment, estimated at $50 million, failed, and the plant ceased operations in 2021 due to low profitability.   Strategic Significance   Observers remain skeptical about whether Russia can expand rare earth metal production as planned.   "From a purely economic perspective, mining rare earth deposits in Russia makes no sense," said an anonymous source in the Russian mining industry. "This plan exists because, under the current geopolitical circumstances, we [Russia] do not want to rely on imports of these critical raw materials, even if they come from friendly countries."   "It can be argued that Russia continues rare earth production precisely because these minerals are of strategic importance to the national economy," the source added.   "One of the key issues in Russia’s rare earth metal industry is the lack of necessary technology," explained Igor Yushkov, a senior analyst at the National Energy Security Fund and an expert at the Russian Financial University. "Given the sanctions, Russia essentially needs to develop almost all the equipment required for mining and processing rare earth metals."   As a result, the cost of rare earth production in Russia is expected to rise further, Yushkov noted. While the state assistance promised under the recent industrial development plan may provide some support, it does not guarantee long-term profitability.   Yushkov believes that former U.S. President Donald Trump’s interest in rare earths could impact Russia’s rare earth industry. In February, Russian President Vladimir Putin suggested that the United States might be interested in exploring joint rare earth metal deposit exploration in Russia.   Yushkov pointed out, "A U.S. withdrawal of sanctions on the transfer of rare earth mining technology and permission for American companies to invest in rare earth deposits could facilitate the rapid development of Russia’s rare earth metal industry."     Article Source: https://geoglobal.mnr.gov.cn/zx/kydt/zhyw/202508/t20250827_9966973.htm

New Exploration Breakthrough at Ecuador's Fruta del Norte Gold Mine
According to Mining.com, Lundin Gold has intersected high-grade mineralization in drilling at its Fruta del Norte (FDN) mine, located 400 kilometers southeast of Quito, Ecuador. The most significant intercept was 9 meters grading nearly 140 g/t gold.   Drill hole FDN-C25-238, targeting the Fruta del Norte South (FDNS) deposit, intersected mineralization at 62.2 meters depth. In addition to the high-grade intercept, the hole also revealed: 11.5 meters at 28.62 g/t gold 9.45 meters at 9.77 g/t gold Another hole, FDN-C25-245, encountered 9.8 meters at 43.77 g/t gold at 102.7 meters depth.   Ron Hochstein, President and CEO of Lundin Gold, stated in a press release: "Ongoing resource upgrade drilling at FDNS continues to intersect high-grade mineralization beyond the current inferred resource boundary, along a newly discovered vein structure." "Recent drilling at Fruta del Norte East (FDNE) continues to demonstrate its significant exploration potential, located adjacent to our existing underground workings." Extending Mine Life These results are part of the company’s near-mine exploration strategy, aimed at extending FDN’s 12-year mine life through resource expansion, new discoveries, and upgrading inferred resources to indicated status. Ongoing engineering studies aim to integrate FDNS into FDN’s long-term mine plan next year.   Exploration efforts over the past three years have significantly increased resources and led to new discoveries. FDN, which began production in 2020, achieved a record output of 502,029 ounces of gold last year, making it one of Ecuador’s two large-scale commercial mines. Additional High-Grade Intercepts at FDNS Another notable intercept at FDNS was 8.1 meters at 31.63 g/t gold at 38.6 meters depth. The resource upgrade drilling has confirmed continuity of the FDNS mineralization, while high-grade intercepts outside the current geological model suggest strong potential for further resource growth. Growth Potential at FDNE At Fruta del Norte East (FDNE), drill hole UGE-E-25-207 intersected 10 meters at 6.61 g/t gold at 497 meters depth. Recent drilling has expanded FDNE’s northern extension, highlighting additional areas for growth. 2024 Drilling Program This year’s drilling program includes at least 108,000 meters, with 83,000 meters dedicated to exploration and 25,000 meters for resource upgrades. The company currently has 10 rigs operating on site. FDNS Deposit Overview FDNS is an epithermal vein system with an estimated inferred resource of: 12.4 million tonnes 5.25 g/t gold 2.09 million ounces of gold       Source: https://geoglobal.mnr.gov.cn/zx/kcykf/ztjz/202508/t20250807_9944985.htm
