Froth Flotation: Froth flotation is a common method used to separate copper minerals from the gangue (waste rock) and other minerals in the ore. In this process, the crushed and ground ore is mixed with water and chemicals, including collectors, frothers, and modifiers, which selectively attach to the copper minerals and make them hydrophobic ...
