Extracting a metal from its ore - chymist

2006-6-27 · Aluminum, calcium, sodium and other active metals are extracted using electrolysis. Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O
