· copper processing copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractorylined furnace of either the hearth or ...

Once mined, copper ore goes through a series of processing stages in order to refine it into a saleable copper product. Copper can be refined by one of two approaches: pyrometallurgy or hydrometallurgy. Pyrometallurgical Copper Refining. The pyrometallurgical approach, often referred to as smelting, is the primary method used for refining copper.
