Top Copper Producing Countries In The World
Apr 25 2017Mining operations extract copper from the ground via open pit mines Once the copper-containing earth is extracted the extract is ground to fine ore and put through a froth flotation process This process combines the ore with water and a collector chemical that makes copper hydrophobic (a condition which repels water) Get price
