Which method is commonly used to extract copper?

Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.

What are the steps for extraction of copper from its ore?

Extracting of Copper from Other Ores

  • Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
  • Concentration of the copper(II) sulfate solution by solvent extraction.
  • Electrolysis of the new solution.

Where and how is copper mined?

Ore is first mined, then put through a series of processes to refine and purify the copper. The USA is the second largest producer of copper in the world. The largest copper mine is found in Utah (Bingham Canyon). Other major mines are found in Arizona, Michigan, New Mexico and Montana.

What mineral is copper extracted from?

Most of the world’s copper comes from the minerals chalcopyrite and chalcocite. Chrysocolla and malachite also are mined for copper. Other copper-bearing minerals include atacamite, azurite, bornite, brochantite, cuprite (copper oxide), dioptase, rosasite and tetrahedrite.
