Sulfide Ores - an overview | ScienceDirect Topics

Copper, zinc and nickel are recovered from the pregnant leach solution by sequential hydrogen sulfide precipitation of separate metal sulfide precipitates. The heaps are typically leached for 1.5 years. The planned production of nickel in the sulfide precipitate is approximately 50 000 tonnes per year.

Nickel processing - Extraction and refining | Britannica

Nickel concentrates may be leached with sulfuric acid or ammonia, or they may be dried and smelted in flash and bath processes, as is the case with copper. Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which …
