Flotation of Gold and Gold-Bearing Ores
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.

General Process of Copper Sulfide Ore Flotation
This process is more advantageous for copper-sulfur ores where the raw ore contains low sulfur, and the copper minerals easily float. Copper and sulfur minerals are first mixed and floated in a weakly alkaline slurry. The mixed concentrate is added with lime to separate copper and sulfur in a highly alkaline slurry. 3.
