Beneficiation of nickeliferous laterite by reduction

May 01, 2012 Highlights Ni beneficiation of laterite ore by using direct reduction process is proposed. Sodium sulfate is capable of intensifying the reduction roasting of laterite. Average particle size of ferronickel grows up to 50 μm when reduced with Na 2 SO 4. Selective enrichment of Ni can be realized by suppressing the metallization of Fe. New-born troilite (FeS) facilitates the aggregation of

WO2010078787A1 A laterite beneficiation process for

A beneficiation process for enriching nickel and/or cobalt involves the steps of dividing nickel laterite into limonite type ore and serpentine type ore to beneficiate separately; classifying by screening at least one time after washing the ore; beneficiating separately the products of the various grades obtained; further classifying by gravity separation and magnetic separation to obtain the

(PDF) Chemical Beneficiation of Lateritic Rare Metal

Despite the high grade, recovery of rare earths from laterite ores by conventional mineral beneficiation processes such as froth flotation, density or magnetic separation is difficult due to the

Beneficiation of Low-Grade Laterite Nickel by Calcination

nickel production is from laterite reserves [1]. One big problem in the way of extracting nickel from laterites is an unequal distribution of nickel in the ore body [2]. On the other hand, the existence of other metals such as silica 1021 will cause some difficulties in the beneficiation process of laterites [3].

Laterite Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which

laterite origin. Marbut's (21) "normal" laterites are those formed under the influence of good drainage free from the action of high ground water. He calls ground-water laterites the soils falling within Fermor's first group. Mohr (23) believes that the laterite crust is the result of eluviation followed by erosion.
