How is copper mined and processed? - JacAnswers

2021-12-30  How is copper mined and processed? 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.

How is copper mined and processed? - AskingLot

How is copper mined and processed? Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes.

How Is Metal Produced From Ore? - Lisbdnet

2022-1-6  How Is Metal Produced From Ore? Metal is extracted from the crushed ore by one of two major methods: smelting or electrolysis. Smelting uses heat to separate the valuable metal from the rest of the ore. . Charcoal burned with hematite ore, for instance, smelts iron. Electrolysis separates metal from ore by using acid and electricity.May 7, 2011.
