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.

The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers. Then the ore is crushed and screened, with the fine sulfide ore (~ mm) going to froth flotation cells for recovery of copper.
