Mining companies accomplish this task by first mixing the copper concentrate with silica and the heating the mixture to 1200°C. This process, which is called smelting, removes many impurities and produces a liquid of copper sulfide that is about 60% copper by weight. This liquid is called copper matte. The mining company then heats the copper
