Dec 10, 2022 · Bacteria feed on the low grade metal ores and form a solution of copper ions, called a leachate. Slow process - it can take years to extract 50% of the metal from a low grade ore. Energy is needed in the elctrolysis step. Energy is needed in the electrolysis step. Then, the copper will be extracted from the leachate by electrolysis or scrap iron.

Early copper mining began at the site in 1900, with open pit stripping beginning in 1959. In 2022, the mine produced 134 million pounds of copper concentrate, paid $ million in state royalties and $ million in tribal royalties, and employed 620 people. The mine is

Copper & Nickel Solvent Extraction. Solvent extraction coupled with electrowinning is an attractive approach for the extraction, separation, and metal recovery because it generally offers (1) leach reagent regeneration, (2) continuous processing, (3) pure metal recovery, and (4) minimum pollution potential.
