Nickel Statistics And Information USGS. The bulk of the nickel mined comes from two types of ore deposits: laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8 ].

Fig. 2 shows the microstructure of nickel laterites and the occurrence regularity of nickel based on the SEM-EDS study. It can be seen that lizardite and goethite are the major mineral constituents and main nickel-bearing minerals containing 1.35% and 0.94% Ni in the two types of nickel laterites, respectively, with characteristics of …

The physical and chemical nature of a nickel laterite deposit is a function of many factors, including the composition of the parent rock, the tectonic setting, climate, topography (specifically, laterite morphology), and drainage. Nickel laterite ore is extracted using both selective and bulk mining methods in open cast mining operations.

Nickel is an important metal globally with a consumption of about 2 million tons per year. This is supplied from both sulfide and laterite ores, but currently laterites are becoming more attractive for nickel production due to the depletion of high grade nickel sulfide ores. Laterites are generally processed through hydro or pyro-
