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.

12.3 Primary Copper Smelting

Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting,
