GCSE CHEMISTRY Extraction of Copper Thermal

2017-3-27  The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated. Thermal decomposition is an endothermic reaction. copper(II) sulfide copper + sulfur dioxide

3.3.4 Copper extraction :: GCSE notes

2015-6-17  Traditional methods. Copper is usually sourced from copper-rich ores in two main methods; Copper can be smelted in a furnace by heating it with air to produce crude copper metal; for example, chalcocite is an ore of copper (I) sulfide, which reacts with oxygen to extract the copper: Cu 2 S (s) + O 2 (g) → 2Cu (s) + SO 2 (g) Copper ore can also be reacted with sulfuric acid to produce copper
