Abstract
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. An alternative embodiment is the recovery of the iron and nickel from the product of the carburizing step by magnetic separation.
