Copper Mining and Processing Processing of Copper Ores

The first steps of copper processing are the same for both ores mining and transporting 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
