Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Sep 25, 2020  6.1. Copper can be extracted by hydrometallurgy but not zinc. Explain. Ans: But with water, these metals (Al, Mg, Ca and K) forms their corresponding ions with the evolution of H 2 gas. Thus, Al, Mg, Ca, K, etc., cannot be used to displace zinc from zinc solution, and only copper can be extracted by hydrometallurgy but not the zinc.
