  • Nickel Metal Properties History Production Uses

    Sulfide ores can be separated using froth flotation and hydrometallurgical or magnetic processes to create nickel matte and nickel oxide. These intermediate products, which usually contain 40-70% nickel, are then further processed, often using the Sherritt-Gordon Process.

  • Sulfide Mining Sierra Club

    Metallic sulfide mining is a type of mining never before permitted in the land of 10,000 lakes. The mining of copper/nickel sulfide ores is a toxic type of mining that is risky to our environment, our workers and communities, and local economies.

  • Pentlandite - Wikipedia

    Pentlandite is the most common terrestrial nickel sulfide. It typically forms during cooling of a sulfide melt. These sulfide melts, in turn, are typically formed during the evolution of a silicate melt. Because Ni is a chalcophile-like element, it has preference for (i.e. it "partitions into") sulfide phases.

  • Nickel Smelting Producing-Metalpedia

    In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then.
