The Extraction of Copper

Extracting of Copper from Other Ores Copper can be extracted from non-sulfide 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 sulfuric acid to produce a very dilute copper(II) sulfate solution
