Investigating Electrolysis Dig Into Mining

Copper ore is first mined, or dug, from the ground. Then, the ore is contacted with a weak acid solution to dissolve the copper mineral and extract it from the rock. Finally, this solution containing copper is purified by electrolysis. How is electrolysis used in mining? Electrolysis uses a direct electric current to create a chemical reaction.

Processes Copper information provided by Copper

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
