  Turning Copper Ore into Copper: What are the Processes?

  2022224 · Typical Copper Extraction Process. The process of extracting copper for its ore is quite complex and varied. It largely depends on the type of ore in question, particularly whether it is a sulfide or oxide type. Copper mining has typically been performed through open-pit mining, where stepped benches are dug deeper and deeper into the ground ...

  Copper extraction is distinctly profitable when the selling price of copper is above $6/kg. It is unprofitable for some operations when the selling price falls below $3/kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid-2011 was ∼$9/kg.

  How Copper is Extracted from Low Grade Ore

  20221230 · The process involves placing the ore on a lined pad and then sprinkling it with a solution that contains sulfuric acid. The acid leaches the copper out of the ore and into the solution, which is then collected and processed to concentrate the copper. Solvent extraction. Solvent extraction is a third method used to extract copper from low-grade ore.
