Copper ore is typically mined through two primary methods: open-pit mining or underground mining. In open-pit mining, large pits are dug into the earth using heavy machinery, and the ore is extracted from the rock. Underground mining, on the other hand, involves tunneling into the earth to reach the copper deposits. 2.
The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel. Copper can also be extracted by displacement from a copper salt solution using scrap iron. Pure copper (99·99%) is needed for good electrical conductivity.
