Read MoreAbstract. This study investigates the reactions of Na 2 SO 4 and its effects on iron and nickel reduction in the roasting of a high-iron and low-nickel laterite ore through gas composition, X-ray diffraction, and scanning electron microscope analyses. Results showed that a reduction reaction of Na 2 SO 4 to SO 2 was performed with roasting up to 600C. However, no clear influence on iron and ...
Read MoreReduction of oxide to the metal. The roasted or the calcined ore is then converted to the free metal by reduction. Reduction method depends upon the activity of metal. Metals which are low in the activity series like Cu, Hg, and Au are obtained by heating their compounds in air metals which are in the middle of the activity cries like Fe.
