The Basics of Copper Mining and Processing. 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.

Mining. Copper can be found in aboveground and underground deposits. The first step in copper production is mining. This can be done via openpit or underground mining methods. Milling. Once the copper ore has been mined, it must be milled to separate the copper from the rest of the rock. This is done via crushing and grinding. Concentrating

Energy costs typically comprise one of the largest ongoing costs of mining operations, of which 70% is devoted to the comminution of the ore (Norgate and Jahanshahi, 2010). Furthermore, the most significant energy cost occurs in the grinding circuit of the Milling section, where up to 97% of the energy cost is incurred (Ballantyne et al., 2012).

Mining techniques did not vary significantly during the various ancient periods. They started with open cast trenches, following the direction of the copper‐containing quartz veins within which the primary copper ores were chalcopyrite (CuFeS 2) occasionally digenite (Cu 2 S) and a few others. These copper minerals were leached by water and, whether directly in the quartz vein itself or in ...
