The dried agglomerated ore is then fed to the rotary kiln with the addition of reductant coal. In the kiln, the ore is completely dried, calcined to remove chemically-combined moisture, and the iron and nickel oxides are partially pre-reduced. Kiln dust is recycled to the process at the primary crushing stage ahead of the dryer/agglomerator.

The nickel content is mainly associated to pentlandite in peridotitic rocks but also enriched in silicates and spinels in mafic rocks (dunites). Industrial plant benchmark data have shown the unfeasibility of establishing a strong relation between the ore chemical composition and its behavior in the mineral beneficiation process.

Abstract: The nickel sulfide fire assay was used to separate and to concentrate the platinum group elements (PGE) and gold (Au) from geological matrices, seeking their analytic determination. The fire assay was accomplished by fusing 10 g of sodium carbonate, 20 g of sodium tetraborate, 1 g of nickel, 0,75 g of sulfur and 10 to 20 g of sample ...
