Nickel Ore - an overview ScienceDirect Topics

Because the ores processed vary widely in terms of nickel content and other components, it is natural that both lower and higher reduction degrees are used. Low reductions imply higher slag losses and lower nickel recoveries but also lower power and reductant requirements, whereas higher reductions imply the reverse (Solar et al., 2008). In some cases, nickel scrap and remelts are added to low-grade FeNi to increase nickel

Preconcentration strategies in the processing of nickel ...

The preconcentration of nickel (Ni) laterite ores ahead of Ni recovery by hydrometallurgical processing makes good economic sense. Since Ni-bearing minerals are often finely disseminated through laterite ores, liberation of minerals either high and/or low in Ni content is a prerequisite prior to any form of separation process. It is the purpose of this paper to investigate the use of flotation ...
