  • How Hydrometallurgy and the SX/EW Process Made Copper

    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.
