  • Nickel laterite ore; an ingredient for stainless steel

    /3/16 Nickel lateritic ore is a metallic mineral resulting from the weathering process and mineral enrichment in ultramafic rocks, which are peridotites containing less than 45% silica. Refining nickel laterite is a very different process and is dependent on whether the ore is a limonite mineral with a nickel content of less than 1.5%, orSLOPE ANALYSIS OF LATERITIC NICKEL ORE DEPOSITS,CONCLUSION. Based on this study, it can be proven that topographical factors greatly influence the formation of nickel laterite deposits. On a gentle to moderate slope, the ore thickness or nickel mineral enrichment is quite high, while on a steep slope, it is still possible for nickel mineral enrichment to occur but not too much, depending on
