Coarse-particle flotation applied to copper sulfide ores

2020-12-9  The largest source of copper supply worldwide comes from copper produced through flotation processes. It is estimated that more than 82% of primary copper production comes from concentration by flotation processes. In Peru, the latest mining megaprojects have been concentrator plants (Cerro Verde, Las Bambas, Constancia, Antapaccay, and so on).
