copper extraction and purification A Level Chemistry

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. Concentration of the copper(II) sulphate solution by solvent extraction.

copper processing Definition, History, Facts

Solvent extraction using organic solvents is of great importance in the purification of leach solutions and in the concentrating of dissolved copper into smaller volumes. Copper from very dilute solutions was formerly recovered by cementation on scrap iron; this produced an intermediate product that was usually returned to a smelter.
