Abstract

This research is aimed to understand the mineralogy of nickel laterite deposit and geochemistry of ultramafic rock, the samples were taken from 14 drilling holes The data is analyzed to conduct weathering geochemical profile to identify lateritization, laterite profile development, characteristics and elements enrichment process in weathering zones. Lithology of the study area is composed by dunite and lherzolite, That dominated by livine, pyroxene and serpentine, also opaque minerals such as chromite and magneti-te with small percentage. Based on X-Ray Diffraction analysis known that the clay mine-rals are chlorite, clinochlore, kaolinite, and dyckite. Based on geochemical analyzes, the mineralogy characteristics of study area showing the different behavior for each element, due to the weathering rate and the dept of cores. The different behavior each element during weathering process determined by different element chemical mobility, forming minerals resistance, weathering intensity and jointing process.

Abstract

Nickel ore is in the region Pomalaa, including the type formed by lateritic weathering of ultramafic rocks (peridotite, serpentine) mineral-rich olivine ((Mg, Fe) 2SiO4) and piroksin (AB Si2O6), The study was conducted to determine the handling and utilization of low grade nickel ore is carried out by PT Antam Tbk. UBPN Southeast Sulawesi. From the research, found that the amount of tonnage of low grade nickel ore (COG <1.8% Ni) compared with high-grade nickel ore (COG> 1.8% Ni). It requires handling as well as on the optimal utilization of low grade nickel ore, which in turn will support the survival of the company.
