GCSE CHEMISTRY - Extraction of Copper - Thermal Decomposition .

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 dioxideExtraction of Copper from Copper pyrite | Grade 12 Science Notes Blister copper consists of about 2% of impurities consisting of cliver, Glod, Zinc, Nicket etc. It is mostly purified by electrolytic method.
