2020-5-2 How is bioleaching used to extract copper? Bioleaching involves the use of microorganisms to catalyze the oxidation of iron sulfides to create ferric sulfate and sulfuric acid. Ferric sulfate, which is a powerful oxidizing agent, then oxidizes the copper sulfide minerals and the copper contained is then leached by the sulfuric acid formed.
