Copper Mining and Extraction Sulfide Ores

Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The world’s largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic activity that is part of the process that created the Andes mountain chain.

Copper mining. From ore to copper.

Mining: Copper can be extracted from its ore by: 1. Traditional mining. underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. 2. Leaching. The ore is treated with dilute sulphuric acid. This trickles slowly ...

Innovations: Introduction to Copper: Mining Extraction

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is ...

Copper Mining and Processing: Everything you Need to

The laborious task of mining copper ore by hand made it difficult to obtain large quantities for production. During the Industrial Revolution, coal- and steam-powered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore per week. At the beginning of the 20th century, the annual worldwide copper demand was at half a million ...
