High Temperature Pressure Oxidation of a Low-Grade Nickel

High temperature pressure oxidation of a low-grade nickel concentrate was examined to demonstrate the potential benefits and shortcomings of this approach. The high iron sulfide content ensured that acid generation was much greater than for higher grade concentrates. This results in the formation of basic iron sulfate phases and a significant amount of sulfuric acid

Mineralogy Notes

In a very general way, metamorphic environments may be classified as low-grade metamorphic (LGM) (temperatures of 60 to 400 C and pressures .5 GPa (=15km depth) and high-grade meta morphic (HGM) (temperatures 400 and/or pressures .5GPa). Minerals characteristic of low- grade metamorphic environments include the zeolites, chlorites

The low grade of the iron ore, where the Fe grade is less than 60% could be upgraded possibly by crushing, grinding, washing, classifying jiggling and de-sliming (Pal et al., 2010). Moreover, a number of quartz and kaolinite particles appear to be coated by goethite, so de-sliming and scrubbing processes could be conducted to remove the
