    Beneficiation of nickeliferous laterite by reduction

    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 size of ferronickel grows up to 50 μm when reduced with Na 2 SO 4. Selective enrichment of Ni can be realized by suppressing the metallization of Fe. New-born troilite (FeS) facilitates the aggregation of ferronickel particles.
