May 01, 1987 · Attempts at the beneficiation of lateritic nickel ore. Int. J. Miner. Process., 19: 2542. The processing of lateritic nickel ore is quite difficult, since the nickelbearing minerals are finely disseminated in the ore bodies. Hence the establishment of beneficiation techniques has long been needed. The authors carried out comprehensive ...

Aug 01, 2015 · Of all these techniques, sizing was the most successful means of beneficiation of laterite ores. Nickel in New Caledonian laterite was higher in the finer fractions with just under 50% reporting to the −37 μm fraction. Magnesium, chromium, aluminium and silicon were concentrated in the coarser fractions.

Limonitic laterite contains low iron and nickel grades and much high smelting minerals and loss on ignition (LOI), identified as refractory iron ore for sintering. Thus, sinter pot tests of limonitic laterite via pressurized densifiion sintering and its intensifiion mechanism were conducted, and the industrial appliion prospect was explored.
