How Do You Mine Copper Ore: A Guide to the Extraction
2023.9.26 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.

Concentration Cu = (5/124) x (1000/100) = 0.4 M. The two concentrations should be the same. However, this calculation works only approximately because ‘basic’ copper carbonate also contains an equimolar amount of copper hydroxide and some water. It should be stressed that copper ores are seldom as concentrated as this.

How Will Copper Contamination Constrain Future Global
Copper in steel causes metallurgical problems, but is pervasive in end-of-life scrap and cannot currently be removed commercially once in the melt. Contamination can be managed to an extent by globally trading scrap for use in tolerant applications and dilution with primary iron sources. However, the viability of long-term strategies can only be evaluated with a
