Nickel Matte Refining Process
Nickel Mining and Processing | General Kinematics
The Nickel Mining Process. ... Nickel matte remains after the mining and processing of either lateritic or sulfidic ore. Using the fluid bed roasting procedure, a 95 percent pure nickel can be achieved after additional refinement. Electric cells provide for a more efficient refining process. The remaining impurities are removed from the nickel ...

But others highlight that, in comparison to other products such as nickel matte, MHP offers a better CO2 footprint. Sources noted that nickel matte can produce up to around 60 tonnes of CO2 per tonne of nickel, due to the energy intensity of the refining process, whilst MHP is thought to be around half of this.

Solid State Extraction of Nickel from Nickel Sulfide Concentrates
Pyrometallurgical smelting and refining is the dominant method of extracting Ni from sulfide concentrates [14, 15].Prior to refining, the concentrate is smelted in an oxidizing atmosphere to yield a Ni-rich matte while simultaneously oxidizing the iron to iron oxide; the iron oxide is fluxed with silica to form an iron silicate slag that is immiscible with the matte [[16], …
