How Hydrometallurgy and the SX/EW Process Made Copper the
Beginning in the mid s a new technology, commonly known as the leachsolvent extractionelectrowinning 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.
