Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process. It appears that selective leaching is a promising method for the beneficiation of this type of ore. However, with the high consumption of leaching ...

1. Introduction. Copper is one of the most important base metals and widely used as wire and conductors. In the earth's crust, copper is most commonly present as copper‒iron‒sulfide and copper‒sulfide minerals, such as chalcopyrite (CuFeS 2) and chalcocite (Cu 2 S) [1, 2].About 80% of the world's copper ores originate in Cu‒Fe‒S …
