  • 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.

  • Smelting of Nickel-Copper and Nickel Sulfide

    Sulfide ores are mostly smelted by matte-making. Different pyrometallurgical processes are used to produce low-nickel matte from various nickel sulfide ores. Then low-nickel matte is converted into high matte, i.e. sulfide and copper sulfide alloys. High matte is then refined by different methods in a refinery to produce different nickel products.

However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.
