Abstract
Calcination-Segregation-Magnetic Separation process was attempted to receover the nickel concentrate for lateritic ores. The application of segregation process to the treatment of the calcined silicate and oxide minerals has involved the admixing of these minerals with calcium chloride and ferro coke followed by magnetic separation. Iron oxide additions significantly increased the recovery of nickel with high nickel content concentrate. At the optimum process conditions, and nickel concentrate was obtained with the recovery of about 80% and the concentrate of about 53% Ni content.
