By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture. The general processes to which low grade iron ores are amenable are as follows: Thermal (a) Drying; removes hydroscopic or atmospheric moisture.

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

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. Get Price
A process for the recovery of nickel and cobalt from laterite ores, the process including the steps of: a) beneficiating the ore to separate it into a beneficiated upgraded ore fraction and a coarse, siliceous low grade rejects fraction which is substantially free from fines and clay materials; b) separately processing the upgraded ore fraction for the recovery of nickel and cobalt; and c ...

Sep 17, 2018· DryProcessing highgrade(> 65% Fe) hematite iron ore are subjected to dry process of beneficiation to obtain calibrated lumps, 40+ 10 mm (for blast furnace); 18+6 mm (for sponge iron) and fines (10/6 mm) products.
The object of the invention is to provide a process for the recovery of iron and nickel from low iron content laterite ores. Said process comprises subjecting the ore to a carburizing step in the presence of a reducing agent and carbon supplying agent to convert the iron to iron carbide, followed by smelting the residue or product of the carburizing step to produce a ferronickel product.

Most ironrich laterites are of little interest, because BIFs are much more desirable ores. However, aluminumrich laterites, called bauxites, are of considerable interest and are the principal ores of aluminum. Bauxites develop either on rocks that are initially low in iron or on ironrich rocks under circumstances in which organic matter or some other special factor renders iron sufficiently soluble to .
