Copper Smelting Chemistry Tutorial AUS-e-TUTE

The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis (electrowinning) for low grade ores, or by the carbon reduction method of smelting for higher grade ores. The process of extracting copper from higher grade sulfide ores involves
