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.

70% of the world's copper resources – estimated to be worth more than $20 trillion – are tied up in primary sulfide ores. The majority of this ore is too low-grade to justify traditional processing, and the alternative low-cost method of leaching does not work well on primary sulfides, despite decades of industry efforts.

Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.
