Processing of Nickel Laterite Ores on the Rise

The Move to Nickel LateritesLateritic Nickel Ore ProcessingConclusionSulfides have long supplied the bulk of the global appetite for nickel. But dwindling resources combined with the need to mine at greater (and subsequently less economic) depths to obtain sulfide ores has many miners looking at nickel laterites. Additionally, nickel is expected to see growth in demand as developing economies spur a greater need for stainless steel. Similarly, demand is expected to grow as a result of nickel’s use in lit在feeco上查看更多信息

Laterite Wikipedia

Laterites are a source of aluminium ore; the ore exists largely in clay minerals and the hydroxides, gibbsite, boehmite, and diaspore, which resembles the composition of bauxite. In Northern Ireland they once provided a major source of iron and aluminium ores. Laterite ores also were the early major source of nickel

These deposits develop from the mechanical and chemical breakdown of high temperature igneous rocks known as ultramafic rocks. These deposits consist of a predictable weathering profile that includes five “zones”: The un-weathered ultramafic bedrock, the weathered bedrock or “saprolite”, a clay-rich layer, limonite zon在geologyforinvestors上查看更多信息

Abstract. Nickel belongs to the transition metal family and shows close chemical similarities with Fe and Co. Even more than these elements, it is concentrated in silicated Fe-Mg minerals by octahedral substitution with Fe 2+ ions. Thus, the mean mineral/ matrix partition coefficient of Ni is 14.0,5.0 and 2.6 for basaltic whole rocks, for olivine, and orthopyroxene and clinopyroxene, respectively.
