Malachite to Copper Equation? | Yahoo Answers
Sep 08, 2010· What is the overall balanced equation which describes the transformation of the basic copper carbonate (malachite) to copper metal? I know in the smelting process there are two steps: 1. CuCO3(OH)2 > 2CuO + CO2 + H2O 2. 2CuO + C > 2Cu + CO but how do you put these together into one equation? Thanks for any help!

Extracting a metal from its ore
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 The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2
