how is copper removed from the earth

2. Mining Methods - Copper

In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task.

Extracting copper. Extracting copper.

Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper. This is similar to …

Copper Mining and Processing: Processing of Copper Ores ...

Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

Copper production & environmental impact

• Copper is distributed in many parts of the world • Copper minerals are divided up into three groups - Primary or hypogene minerals found at great depths - Oxidised copper minerals commonly formed by copper sulfides exposed to erosion - Copper secondary sulfides formed from leaching of sulphides exposed near the earth's surface

Processes - European Copper Institute

The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.
