Jun 07, 2021· Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation).

Sep 26, 2019· Sulfide Copper Ores . Virtually all sulfidetype copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
ChatThe best concentration method for zinc ore is known as froth flotation. Concentration of Ore Froth Flotation Process. Froth Flotation process is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water. The main ingredients of the froth flotation are the Collectors and Froth Stabilizers.
