Application. It is suitable for coarse mineral particle separation (mineral raw materials of any particle size except microfine materials). The suitable particle size of metal minerals is 0.074mm to 50mm. On the prerequisite of weight difference ≥ 1.25 and the ore is dissociated monolithically, the lower particle size limit is 0.04mm.

· Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where <a title="Gold

Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution. Grinding Fineness of Gold For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation; but for the gold with gangue, grinding fineness should reach gold monomer dissociation.

The flotation method is the most widely used ore dressing method in the production of gold. It has high flotation efficiency and can handle fine-grain-dipped ore. For ore with complex composition, the flotation method can get good separation results. Flotation method is often used to treat gold ore containing sulfide minerals with high floatability.

· Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9. Flotation may be carried out at higher pH values of 9–10, since this favors the depression of talc minerals and avoids the use of expensive gangue depressants.
