Copper Mining and Processing Everything you Need to KnowMined 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 produce matte, which then undergoes several refining processes.Copper Mining and Production Processes ExplainedMiningConcentratingRoastingSmelting with Fluxnversion of MatteElectrolytic RefiningLeachingRecyclingThe ore is removed from the ground in either open pit or underground mines. Underground  sinking a vertical shaft into the earth to reach the copper ore and driving h

A. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling CopperSulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ballsize, the crushed ore is further processed at a mill using secondary crushers, and reduced to peb Chat
