Physico-Chemical Characterisation of Lateritic Nickel Ores

The only nickel ore deposit of significance in India occurs in the chrorniferous ultramafic complex ofSukinda, Orissa. It is a lateritic nickel o re deposit with a reserve of about 150 million tonne having cut-off grade of 0.05% Ni. The processing of this ore is difficult due to ultrafine nature ofgeothite, low content of nickel in the ore (max. 1.5% Ni), complex intergrowths of goethite with

The silica content of the Cawse ore is mainly present as iron-rich quartz, whereas in Bulong and Murrin Murrin ore, it is incorporated into clays. In lateritic deposits, the nickel and cobalt do not usually occur in distinct minerals. Along with manganese, they are released

However, it is known that the iron content of the final nickel product must be as low as possible.

Removal of iron from acidic leach liquor of lateritic nickel

The goethite precipitation process uses air as oxidation agent, that is, V.M. method, and does not need the pre-reduction of ferric iron since the soluble iron in leach liquor is mainly ferrous ion. The effects of pH value on the rate of iron removal and the loss of nickel to the residue were investigated.
