WebAs the weathered copper ores in given localities were worked out, the harder sulfide ores beneath were mined and smelted. The minerals involved, such as chalcopyrite, a copper-iron sulfide, needed an oxidizing roast to remove sulfur as sulfur dioxide and yield copper oxide. WebOxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching and Solvent Extraction of Oxide Ore.

WebExpert Answer. Answer 1: Bioleaching is a process wherein microorganisms are used to extract metals from ores or industrial waste products. The microorganisms, most commonly bacteria and fungi, use their metabolism to dissolve the desired metal ions which can then be recovered from the leachate.
