Copper Mining and Processing: Everything you Need to KnowJul 17, 2014 . Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to.Copper extraction - WikipediaMethods 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). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as.
