How Hydrometallurgy and the SX/EW Process Made Copper the

Beginning in the mid 1980s a new technology, commonly known as the leach solvent extraction electrowinning process or, SX/EW 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.
