    • Nickel processing Extraction and refining Britannica

      Various processes are used to treat nickel matte. One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer.In another, the matte may be roasted to produce high grade nickel oxides; these are subjected to a pressure leach, and the solution is electro and carbonyl refined.
