How Is Copper Mined?
Table of Contents. 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.

Minerals | Free Full-Text | Bioleaching Process for Copper Extraction
The extraction of copper and iron increases linearly as the leaching temperature increases from 20 to 60 °C. Copper extraction was 80% after 2 h at 60 °C with the addition of the oxidant ferric sulfate at a concentration of 5 g/L Fe 3+ ions. The highest degree of copper leaching was observed at a stock consistency of 33%.
