Ni beneficiation of laterite ore by using direct reduction process is proposed. Sodium sulfate is capable of intensifying the reduction roasting of laterite. Average particle sie of ferronickel grows up to 50 m when reduced with Na 2 SO 4. Selective enrichment of Ni can be realied by suppressing the metalliation of Fe. New

During the last ten years great strides have been made on the Mesabi range in the practice of beneficiating low grade iron ore material. 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
