copper mining and production processes explained

leaching offers an alternative to copper mining. first the ore is treated with dilute sulphuric acid. this trickles slowly down through the ore over a period of months dissolving copper to form a weak solution of copper sulphate. the copper is then recovered by electrolysis. this process is known as sxew solvent extraction/electrowinning.

gcse chemistryextraction of copperthermal

to extract copper from low grade ores see below. the traditional method of extraction is to heat the copper sulfide. copperii 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.
