Copper extraction techniques refers to the methods for obtaining copper from its ores. The method used to extract Copper Ore depends on the nature of the mineral ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores.
Copper can be extracted from non-sulfide ores by a different process . Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper sulfate solution.
