The Mining Process. Only a small percentage of the rock removed contains copper, so the rock must be crushed and treated. There are two primary types of copper ore, copper oxide and copper sulfide. According to Anaconda, the company mined 103,834,000 tons of copper oxide ore and 58,589,000 tons of sulfide ore.

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.

In Australia, however, underground mining technology rules. Like other ore mining techniques, the equipment used here needs to extract the copper ore, break it down, and get it up to the surface, where it can be processed. The release of pure copper, liberated from the ore, occurs when the crushed materials are dissolved in sulphuric acid

Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.
