Copper Mining and Processing: Everything you Need to Know

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.

What Is Copper Smelting? (with pictures)

Jan 15, 2020· The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities. One of the main side effects of the copper smelting process is the production of waste. Refining copper results in three and a half times as much waste as the amount of copper produced.
