The current work explores improving the beneficiation of nickel from limonitic laterite ore through interaction of silica and calcium sulfate in a selective reduction-wet magnetic separation process.
view more201581 · Abstract The preconcentration of nickel (Ni) laterite ores ahead of Ni recovery by hydrometallurgical processing makes good economic sense. Since Ni-bearing minerals are often finely disseminated through laterite ores, liberation of minerals either high and/or low in Ni content is a prerequisite prior to any form of separation process.

These materials have characteristics of low alumina, high silica and iron oxide content.
view more202161 · As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed. These ores often contain impurities and require some form of beneficiation in order to achieve the typical grades required for sale to downstream steel producers.

It is being taken into consideration to achieve the recovery and utilization efficiently of low-grade nickel laterite ore, especially those containing < 2%wt% nickel. However, laterite nickel ores are not amenable to …
