Extracting copper from other ores. 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.

Copper Recovery in Smelting Slag Recycling

Mintek has developed a leaching process that solubilizes the nickel, copper, and cobalt, while rejecting the iron and any sulphur into the solid residue (by decreasing the pH appropriately). The resulting solution can be processed further to separate the cobalt, nickel, and copper from …
