When working with oxide ores, a hydrometallurgical leaching process is typically utilised. This process makes use of aqueous water-based solutions to extract and purify copper from copper oxide ores at normal temperatures. This process could include three steps heap leaching, solvent extraction, and electrowinning. Heap Leaching
Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SXEW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20 of all copper produced is produced by this is process.
