Copper extraction WikipediaCopper 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).Mineral processing WikipediaThere are a number of cells able to be used for the flotation of minerals. these include flotation columns and mechanical flotation cells.
