Innovations: Introduction to Copper: Mining Extraction

Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.

    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!
