Indonesia, the world's largest nickel producer, is considering raising its nickel and other mineral royalties paid by mining companies, the mining journal (Mining Journal) reported.   On March 10, Reuters reported that the Indonesian government would impose a 14-19 percent premium on nickel prices, with a unified tax rate of 10 percent.   There are also reports that Indonesia will impose a progressive tax on nickel and nickel.   On copper ore, the proposal proposes an increase from a 5% uniform tax to 10-17%, as well as copper concentrate and electrolytic copper.   At the same time, if coal prices exceed $90 a ton, the royalty tax rate will be raised by 1 percentage point to 13.5 percent.   The Indonesian government has imposed a progressive tax on coal, with a calorific value of 4,200 kcal / kg, and a minimum premium rate of 8% if the price exceeds $90 / ton.   The proposal also involved minerals including tin, gold, silver and platinum, but no details were given.   The change is reportedly in support of the president of Prabowo Subianto's big spending plan.   Article source: https://geoglobal.mnr.gov.cn/zx/kczygl/kysf/202503/t20250312_9272600.htm

Canada has extended its mineral exploration tax credit by two years as a measure to support exploration projects, energy and natural resources investments, Jonathan Wilkinson said on Sunday, citing Reuters.   The Mineral Exploration Tax Credit is a capital market tool that provides a 15% tax credit for investors who buy tradable shares in small mining companies. The policy expires on March 31.   Mr Wilkinson said the extension was intended to ensure that the mining industry had the tools to finance exploration projects. The measure is also a government's attempt to provide alternative sources of funding for businesses.   At present, Canadian mining enterprises are in financing difficulties, and the government is facing the challenge of overseas funds.   In an interview, Wilkinson said junior companies were eager to get funding and the extension was expected to provide C$111 million support for mineral exploration.   The measure will be announced at the Toronto Exploration Annual Conference (PDAC) on Sunday (March 9). PDAC is one of the world's largest mining conferences.   Mining companies in North America could face a trade war launched by U. S. President Donald Trump, who has threatened to impose a 25 percent tariff on most Canadian goods.   Mining companies will also face tight controls on key mineral exports. Wilkinson said Canada and the United States can mutually benefit, and Canada can provide the United States with the much-needed supply of gallium and germanium.   Mr Wilkinson said Canada and the US could sit down and talk seriously about how to help each other. If Mr.Trump insists on imposing tariffs on Canada and Mexico, Canada is ready to retaliate.   While Canada may not impose an export tax on metals in the first round of countermeasures, consider future taxes on Zinc, Copper and Nickel.   "This may not be the first step, but it is certainly a measure in the Canadian policy box. We are not going right now."   Article source: https://geoglobal.mnr.gov.cn/zx/kczygl/zcdt/202503/t20250304_9265792.htm

British prime minister Stammer said Monday the proposed key mineral deal with Ukraine was not enough to be a security guarantee in any peace plan, Mining.com reported, citing Bloomberg News Agency. This clearly shows that the European leaders intend to persuade the United States to provide stronger defensive support.   The US plans to take some of the proceeds from Ukraine's natural resources to supplement its military support for the latter, a deal that was not signed after Trump's public row with Zelensky on February 28. At the time, Zelensky said he did not think the agreement planned to sign would bring peace, infuriating Trump and Vice President Vance, but Stammer appeared to have the same view on Monday.   "A mining agreement alone is not enough," the British prime minister said in the House of Commons. He said the United States was "crucial" to achieving peace in Ukraine.   The Trump administration is now trying to strike a peace deal with Russia, and Stammer wants to act as a bridge between Britain's European ally and the United States on Ukraine. European countries, including Britain and France, are drafting their own peace plans for Ukraine, presented to Trump in the coming weeks. It depends on whether the United States provides air reconnaissance, surveillance and cover as a last resort to assist European peacekeepers when attacked by Russian forces after the peace agreement is signed.   On Monday, Trump criticized Zelensky and Europe on the "real social" platform, accusing the Ukrainian leader of not wanting peace and suggesting that Europe was unwise that "they could not do it without America."   Last week, Mr.Trump was delighted at the invitation of King Charles III during his first meeting after he reentered the White House. After Zelensky's disastrous talks with Trump and Vance at the White House, Stammer spoke with Trump twice in two days.   Mr Trump claimed that key mineral sharing agreements were enough to provide security because of the presence of American workers in Ukraine. But Stamer said on Monday that continued U. S. support is necessary while European countries increase defense spending.   "We see clearly that we are facing the test of our times, that we are at a crossroads in history," Stammer told members after a weekend diplomatic event in London.   "We are once again living in a time when European peace depends on strength and deterrence," Stammer said, highlighting the prime minister's determination to strive for a voice in Ukraine and the future of Europe.   Stamer also stressed that sanctions against Russia cannot be lifted if a ceasefire is reached.   He added that while other European countries have expressed their willingness to join the so-called "comfort force" (Reassurance force) composed of British and French air forces and troops in Ukraine, not all countries "take the same position" on the issue.   Stamer said details of the peace plan were still being developed and "no guarantee of success".   He also believes that transatlantic Allies need to do more to make billions of dollars of frozen Russian assets is "complex".     Article source: https://geoglobal.mnr.gov.cn/zx/kczygl/zcdt/202503/t20250305_9267097.htm

According to BNAmericas website, the Chilean Ministry of Mines has announced the 2025-26 tailings agenda, proposing legislative amendments to upgrade domestic standards to international standards and conducting registration to identify important tailings.   This agenda aims to strengthen tailings management in the country. According to data from the Chilean Geological Survey (Sernageomin), out of 795 tailings ponds, 475 are idle and 176 are abandoned.   The plan solicited opinions from both the public and private sectors. One key goal is to develop guidelines and modernize the regulatory system. The current laws regarding the design, construction, and operation of tailings facilities were enacted in 2007. This strategy lists three tasks:   ——Strengthen the inspection, filing, and visualization of tailings data, and consider developing a comprehensive information platform for this purpose;   ——Contact the owners of tailings dams, encourage the relocation and restoration of tailings, and promote feasibility studies, environmental impact assessments, and relocation pilot projects;   ——Implement tailings resource utilization projects to promote the redevelopment and reuse of tailings, extracting elements such as copper, iron, titanium, cobalt, and rare earths from them.   At the end of next year, the Chilean government will release a technical guide to guide tailings reuse projects and provide financing tools or encourage related suggestions.   Chilean Mining Minister Aurora Williams encourages the industry to implement these measures.   According to Sernageomin's data, there are currently 15 tailings dams under construction. This includes Codelco's Salvador copper mine, Enami's Matta beneficiation plant, and Minera Gold's Salares Norte project.   Sociedad Punta del Cobre is expanding the El Espino tailings pond in the Coquimbo region, while Mantos Copper is constructing a tailings dam for the Mantoverde project in the Atacama region.       Original source: https://geoglobal.mnr.gov.cn/zx/kczygl/zcdt/202502/t20250206_9244402.htm

This is in line with the strategic partnership between the UK and Botswana, which aims to promote economic development, environmental sustainability and social progress.   According to MiningWeekly, Raymond Edward Harry Collins, Baron Highbury, the British Secretary of State for African Affairs, recently visited the Jwaneng diamond mine operated by Debswana during his visit to Botswana.   The visit highlighted the strategic importance of the partnership between the UK and Botswana.   During the inspection, Collins had in-depth exchanges with Andrew Motsomi, the manager of Debusswana Company. Motsumi stated that the 55 year history of Derbyswana Company is built on safe, efficient, responsible, and ethical diamond mining.   He emphasized the company's contribution to Botswana's economy, including promoting infrastructure, health care and education development.   Motsumi also provided a detailed introduction to the production and operation situation, challenges faced by the company, and development opportunities in the past year.   "We are proud of our long-term commitment to responsible mining practices and our contribution to Botswana's economic and social development. The focus of our work is still to ensure that the communities we serve can feel the benefits of the mine, and we are also constantly exploring new opportunities to enhance our influence," Motsomi said.   Collins expressed admiration for Debusswana's ESG practices and noted the company's efforts to sustain economic activities beyond diamond mining.   These initiatives are critical to Botswana's long-term economic stability and growth.   Collins also discussed potential cooperation opportunities in the field of renewable energy and praised Derbyswana's efforts in sustainable development practices.   This is in line with the strategic partnership between the UK and Botswana, which aims to promote economic development, environmental sustainability and social progress.   While Derbyswana is making every effort to get rid of the downturn in the diamond market, Collins' investigation and visit to the Juwaneng diamond mine will help deepen the bilateral relations between the United Kingdom and Botswana.     Article source: https://geoglobal.mnr.gov.cn/zx/kczygl/zcdt/202501/t20250122_9238225.htm  

According to MiningWeekly, international mining giant Rio Tinto announced a decline in production at its iron mines in the Pilbara region for the fourth quarter and full year of 2024, due to resource depletion and unusually heavy rainfall. The increase in productivity has not fully offset these impacts.   Rio Tinto's fourth quarter and full year iron ore production were 74.2 million tons and 284.6 million tons, respectively, with a decrease of 1%.   On the contrary, the copper production situation is completely different. Due to the increase in production at the Oyu Tolgoi underground copper mine in Mongolia and the Escondida copper mine in Chile, offsetting the impact of production interruptions caused by unstable slopes at the Kennecott copper mine in the United States, the company's production has significantly increased.   The copper production in the fourth quarter was 202000 tons, a year-on-year increase of 26%; The annual output was 697000 tons, an increase of 13%.   The company's bauxite production has increased, with a slight increase in aluminum products.     Original source:https://www.worldmr.net/Industry/IndustryList/Info/2025-01-20/308290.shtml

The signing of this MoU marks both nations' commitment to becoming key players in the global critical minerals supply chain.   India Expands Critical Minerals Exploration in Latin America MiningWeekly reported on September 18 that India's Minister of Mines, V.L. Kansa Rao, stated that the state-owned Coal India Limited is actively exploring critical minerals in Argentina and is in talks with the Chilean government regarding lithium resource cooperation. In June, Coal India began lithium exploration activities in Argentina in collaboration with a U.S. company, as part of India's strategy to secure battery materials within the MSP framework led by the United States. Additionally, the state-owned KABIL (Khanij Bidesh India Limited) is exploring critical minerals in Australia and has received approval to conduct non-invasive, "green" exploration in Argentina.   UN Releases Guidelines on Critical Minerals for Energy Transition Reuters reported on September 17 that the United Nations has launched its Fair and Just Guidelines for Critical Minerals Driving the Energy Transition. The report outlines pathways to achieve a just and equitable renewable energy revolution, promoting sustainable development, human rights, environmental protection, and prosperity for resource-rich developing nations. In April, UN Secretary-General António Guterres established a special expert group to develop recommendations and guidelines to help governments and mining companies secure energy transition minerals while safeguarding human rights, justice, and fairness. The group recommends establishing a high-level expert advisory panel within the UN to convene stakeholders for policy dialogue on economic issues across the mineral value chain. The guidelines also advocate for a global system of traceability, transparency, and accountability, and propose a fund to address historical environmental issues such as abandoned or orphaned mines. The group further suggests empowering artisanal and small-scale miners to become key contributors to development, environmental governance, and human rights protection, promoting material efficiency and recycling.   Canada Invests Over CAD 8 Million to Boost Critical Minerals Recycling in Ontario According to the website of the Canadian Ministry of Natural Resources on September 15, the Canadian government has allocated CAD 8.4 million to support critical mineral recycling technologies in Ontario, aiding the electric vehicle supply chain.

Green Graphite Technologies (GGT) will receive CAD 3.5 million to advance its GraphRenew technology, which converts used graphite into reusable material.

Modifiers are agents used to adjust the action of collectors and the conditions of the flotation medium. They include activators that promote the interaction between collectors and the particles of unwanted minerals, pH modifiers that adjust the pH of the medium, depressants that inhibit the floatability of non-target particles, dispersants that maintain unwanted fine particles in a dispersed state, and flocculants that encourage target fine particles to agglomerate into larger clusters.   Modifiers are one type of flotation reagent used to modify the surface properties of minerals and the characteristics of the slurry (such as the composition of the liquid phase, frothing performance, foam properties, etc.), improving the selectivity and conditions of the flotation process. Based on their primary function in the flotation process, modifiers can be classified into depressants, activators, pH modifiers, flocculants, and others.   What is the Classification of Modifiers? Modifiers can be categorized into five types:   1. pH Modifiers These reagents are used to regulate the pH of the slurry, controlling the surface characteristics of minerals, the chemical composition of the slurry, and the conditions of other reagents, thereby improving flotation performance. In cyanidation processes, pH regulation is also necessary. Common pH modifiers include lime, sodium carbonate, sodium hydroxide, and sulfuric acid. In gold extraction, lime and sulfuric acid are the most commonly used modifiers.   2. Activators Activators enhance the interaction between minerals and collectors, allowing difficult-to-float minerals to be activated and float. For example, sodium sulfide is used to activate gold-bearing lead and copper oxide ores, which are then floated using collectors such as xanthates.   Click the image below to get more details of our activators! 3. Depressants Depressants increase the hydrophilicity of minerals and prevent them from interacting with collectors, thereby inhibiting their floatability. For instance, lime is used to depress pyrite in preferential flotation, while zinc sulfate and cyanide are used to depress sphalerite. Silicates, such as sodium silicate (water glass), are used to depress silicate gangue minerals, while organic substances like starch and tannin are used to achieve selective flotation separation of polymetallic ores.   4. Flocculants Flocculants cause fine mineral particles to aggregate into larger particles, accelerating their settling rate in water. Selective flocculation can be used for flocculation and de-sliming, or for flocculation and flotation. Common flocculants include polyacrylamide and starch.   Click the image below to get more details of our flocculant!   5. Dispersants Dispersants prevent fine mineral particles from agglomerating, maintaining them in a monomeric state, opposite in function to flocculants. Common dispersants include sodium silicate and phosphates.   What are the Functions of Modifiers? In the mineral processing process, flotation is the method of concentrating minerals by taking advantage of the natural differences in hydrophobicity between different minerals in the ground ore slurry. For effective separation of minerals in finely ground ore, reagents must be added to the slurry, which is then agitated and aerated. Minerals that attach to air bubbles float to the surface, while non-floating minerals remain in the slurry, leading to mineral concentration. The reagents used in flotation, apart from collectors and frothers, are collectively referred to as modifiers.   The function of modifiers is to adjust the interaction between collectors and minerals, either promoting or inhibiting their floatability, and to regulate the pH and ionic composition of the slurry.   Conclusion In summary, modifiers play a crucial role in the flotation process by modifying the surface properties of minerals and optimizing the conditions within the slurry. Whether it's adjusting pH levels, activating certain minerals, or inhibiting others, modifiers enhance the selectivity and efficiency of mineral separation. Understanding the various types and functions of modifiers is essential for optimizing flotation processes and achieving desired mineral recovery rates. By carefully selecting and applying these agents, operators can significantly improve the overall performance and economic outcomes of mineral processing operations.   Y&X Beijing Technology Co., Ltd. specializes in delivering comprehensive mineral processing solutions for both metallic and non-metallic ores, with a focus on environmentally sustainable and highly efficient reagents.

To enhance the selectivity of the flotation process, strengthen the effect of collectors and frothers, reduce the mutual inclusion of useful mineral components, and improve the conditions of the flotation pulp, regulators are commonly used in the flotation process. Flotation regulators include many reagents, and they can be classified into depressants, activators, pH modifiers, defoamers, flocculants, and dispersants based on their roles in the flotation process.   Activators are a type of flotation reagent that enhances the adsorption capacity of minerals on collectors. The activation mechanisms include: (1)Forming an insoluble activation film on the mineral surface that readily interacts with collectors; (2)Creating active sites on the mineral surface that readily interact with collectors; (3)Removing hydrophilic films from the mineral surface to enhance the floatability of the mineral surface; (4)Eliminating metal ions in the slurry that hinder the flotation of target minerals.   Copper sulfate activators are important activators.   Properties and Classification of Copper Sulfate Activators The role of copper sulfate activators in mineral flotation primarily involves altering the chemical properties of the mineral surface to enhance its flotation performance. Here's how it works:   1. Chemical Reaction: Copper sulfate (CuSO₄) acts as an activator in the flotation process, primarily to promote the flotation of certain minerals. It reacts with the mineral surface, especially with sulfide minerals such as pyrite and sphalerite, forming copper ions (Cu²⁺) and other compounds. These copper ions can bond with the sulfides on the mineral surface, altering the chemical properties of the mineral surface.   2. Changing Surface Properties: The addition of copper sulfate creates a new chemical environment on the mineral surface, altering its hydrophilicity or hydrophobicity. For example, copper ions can make the mineral surface more hydrophobic, increasing its ability to attach to air bubbles during flotation. This occurs because copper sulfate reacts with the sulfides on the mineral surface, thereby altering the surface charge and hydrophilicity of the mineral.   3. Enhancing Selectivity: Copper sulfate can increase the selectivity of the flotation process by activating the flotation of specific minerals. For certain minerals, it can significantly improve their flotation rate and recovery. This is because activation makes the mineral surface more prone to combining with flotation reagents (such as collectors), thereby enhancing the efficiency of the flotation process.   4. Promoting Collector Adsorption: By altering the surface properties of minerals, copper sulfate can promote the adsorption of flotation collectors (such as xanthates and dithiophosphates). This promotion enables collectors to more effectively bind to the mineral surface, enhancing the collecting capacity and selectivity of the flotation process.   In summary, copper sulfate, as an activator in mineral flotation, primarily works by altering the chemical properties of the mineral surface, increasing its hydrophobicity, and promoting collector adsorption, thereby improving the flotation performance and selectivity of the mineral.   Y&X's Copper Sulfate (CuSO₄) is a powerful activator for sulfide ores like sphalerite, pyrite, and pyrrhotite, ensuring efficient and selective flotation in your mining processes.

A classic example is in the flotation of copper ores. In the processing of copper ores, copper sulfate is often used to activate pyrite, enhancing its flotation performance with collectors such as xanthates. Through the action of copper sulfate, the surface of pyrite becomes more amenable to the adsorption of collectors, thereby improving the recovery rate and flotation efficiency of copper ores. Another example is the flotation of lead-zinc ores, where copper sulfate is used to activate sphalerite, improving its performance in the flotation process. These applications underscore the importance of copper sulfate as an activator in mineral flotation.     Y&X Beijing Technology Co., Ltd. is a trusted provider of comprehensive beneficiation solutions for metal and non-metallic mines, focusing on environmentally friendly and highly efficient reagents.
