P rinciples of Metal Extraction: Metals are found in the combined state in ores where they exist as positive ions. During the extraction of metals, the metallic ions must first be reduced to the corresponding metal atoms. This reduction process can be done electrolytically or by thermal or chemical methods.
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.
