Problem:

• Pyrite has high content and good floatability, so it is difficult to separatefrom chalcopyrite黄铜矿;
• Serpentine, talc content up to 60%;
• Chalcopyrite exists in very fine particleFoam viscosity is not conducive to the

Technical solution:

• The high efficiency copper collector YX091 is used, which has a strong ability to collect copper but a very weak ability to collect pyrite;

• Stage grinding and stage sorting process to avoid serpentine and talc slime intensification;;

• Use serpentine to effectively separate serpentine-talc from chalcopyrite on depressant;

• With efficient frother Q92, which has foaming speed is fast the foam is fresh and easy to dissipate, the grade of copper concentrate is improved, and the separation of copper and gangue is promoted

 Final effect:

• Copper concentrate content increased from 12% to 18%;

• Copper recovery rate increased from 72% to 83%;

• The cost of mineral processing agents decreased from RMB 15 yuan/ton to RMB 9 yuan/ton
