Product Description

High Efficiency Sulfur Depressant DS101 For Pyrite And Pyrrhotite




Depressant DS101 is a highly efficient sulfur depressant for pyrite and pyrrhotite, which is self-developed by Y&X campany.

Depressant DS101 is an environmental friendly solution.  It is particularly suitable for various types of ores such as copper ore, lead-zinc ore, and copper lead-zinc ore. Under low or non-alkaline conditions, it effectively suppresses the formation of pyrite and pyrrhotite while exhibiting minimal depressant effects on minerals like chalcopyrite, galena, and sphalerite. Notably, it has the potential to fully or partially replace lime in the process.


Physical State
Colorless liquid
Slightly odorous
Specific Gravity






With the development of society, the resource utilisation rate is increasing, the nature of the ore is getting more and more complicated, and the technical difficulty of ore dressing is getting bigger and bigger. Complex polymetallic sulphide ore original ore nature is variable, close symbiotic relationship, account for each other, especially copper and sulphur minerals are very similar in nature, they are embedded in microfine grains symbiosis, separation is very difficult.
At present, the most widely used method to inhibit pyrite is the lime method. This method has good separation effect, can obtain high copper concentrate grade and recovery rate, but the use of high alkali medium leads to the traditional process there are unavoidable defects: in the high alkali medium, lime on the ore copper, sulfur, gold, silver and other minerals have different degrees of inhibition, not conducive to the further improvement of the copper index, especially not conducive to the accompanying gold, silver and other valuable metals of the comprehensive recovery; copper tailings of sulfur is strongly inhibited, only by adding activator to achieve the copper tailing election of sulfur, resulting in a serious waste of resources, increasing the cost of flotation; and lime in industrial production in large quantities, prone to plugging, scaling, easy to corrode the equipment; in addition, the beneficiation wastewater of the process of high alkalinity, high cost of wastewater treatment.
Therefore, the development of a new, environmentally friendly, safe pyrite inhibitor has been imperative, in line with the current energy-saving and environmental protection national policy, but also for the enterprise to solve the problem of high alkalinity of wastewater.


The mechanism of action for this pyrite depressant involves its reaction with the surface of pyrite upon introduction into the slurry. This reaction leads to the formation of a stable complex, rendering the surface of pyrite hydrophilic and preventing its adsorption with bubbles. Consequently, the treated pyrite is unable to enter the flotation foam layer and instead becomes a foam product, facilitating the separation of pyrite from the desired target minerals.
