copper can be extracted from non-sulphide ores by a different process involving three separate stages: reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(ii) sulphate solution.,how copper is made - material, used, processing, steps,process the process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
the metal copper can be easily extracted but copper–rich ores are becoming scarce so new methods of extracting copper are being developed to exploit low grade ores. a low grade ore is one with low concentrations of copper and research is going on to try and exploit waste material left over from processing high grade ores.,copper statistics and information - usgs.gov,pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. an increasing share of copper is produced from acid leaching of oxidized ores.
