Physical beneficiation and metallurgical processes alone cannot be used for the processing of Indian lateritic overburden. In this article, studies carried out on complex lateritic overburden using a combination of physical and pyro-metallurgical process for making pig iron nugget from the overburden is discussed. Physical beneficiation has enriched the Fe content to 52.74% with a weight per cent recovery of 59.67% having Ni-0.9% from the feed assaying 46.73% Fe (T), 0.76% Ni. This beneficiated nickel enriched iron was used for the production of pig iron nuggets which has given a composite product containing Ni~1.7%, Cr~ 1.5%, C~ 3% and Fe-rest with recoveries of iron, chromium and nickel as > 95%, > 95% and -40%, respectively.
