Extracting a metal from its ore chymist

2006-6-27  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

Chemical analysis of copper ore Free Essays Studymode

Copper ores. containing copper compounds (such as copper carbonate) are called ‘copper ore’.Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes.Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚
