The total copper recovered from its ore through flotation process is about 56% [6,18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).The mixed-priority flotation process is suitable for the extraction of copper from dense massive sulfide ore and disseminated sulfide ore with a non-sulfide content of more than 10-15%. The process flow is shown in the figure below. Most of the gangue is discarded in the mixed flotation circuit, so the copper concentrate grade can be improved.

The commonest ore for Copper extraction is Chalcopyrite. The proportion of copper is very low so it needs to be concentrated by the process of froth flotation. In copper smelting, the concentrated ore is heated strongly with silicon dioxide, calcium carbonate, and air in the furnace. Collectors and froth stabilizers are used during the ...Copper extraction from Copper Pyrites. The extraction of copper from copper pyrites is done using the following methods. 1) Concentration of ore: In this process, the ore is crushed to a fine powder. Then, the mineral is separated from the other particles using the froth flotation method.
