Mining Industry Profile Copper US EPA

Mining Industry Profile Copper US EPA

Waste rock and ore are relative terms in the context of copper porphyry ore bodies since few distinct boundaries exist.iron ore equipment for dolomite in the uae Prominer. Usually, contacts between mineralization zones are gradational; there is a gradual increase in mineralization from nonmineralized areas to quality ore areas. Therefore, waste rock may contain some values. (U.S. DOI, Bureau of Mines 1965a).
