The carbonic materials used were molasses, coal, and coke. Additional tests were conducted on a piece of ore, and coke and molasses mixture. Colombian nickel laterites were pulverized through a size 100 mesh (150 microns), mixed with reducing agents, and then compacted in a hydraulic press at a force of 25 MPa.

Laterite Ore

The laterite ore is dried and reduction roasted in multihearth roasters in an atmosphere containing hydrogen and carbon monoxide in the absence of air. Nickel and cobalt are selectively reduced to the metallic form and thus rendered amenable to ammoniacal leaching, while iron remains as insoluble oxides and silicates.

Generation process of FeS and its inhibition mechanism on ...

2015-9-8 · Numerous studies have demonstrated that Na2SO4 can significantly inhibit the reduction of iron oxide in the selective reduction process of laterite nickel ore. FeS generated in the process plays an important role in selective reduction, but the generation process of FeS and its inhibition mechanism on iron reduction are not clear. To figure this out, X-ray diffraction and …
