Copper electrowinning | De Nora

Mixed metal oxide (MMO)-coating titanium anodes are gaining acceptance even in copper electrowinning versus lead alloy anodes, still fitting the majority of commercial metal electrowinning plants. Primary copper producers have already proved the advantages of titanium anode technology over conventional lead anodes:.

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.
