The principal copper minerals are bornite, chalcopyrite, tennantite-tetrahedrite and chalcocite, with minor covellite and native copper. The tennantite-tetrahedrite series of minerals also has the feature that some of the copper atoms in the crystal lattice can be replaced by other heavy metals, such as zinc and mercury.

Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps.
