The manganese nodule residue, generated in ,eduction roast ammonia leaching process has emerged as potential seco-ndary raw material for production of ferrosilicomanagese. In the present paper, the smelting studies of low mang-anese containing leached manganese nodules residue blended with,high grade Mn ore has been carried out in electric arc furnace for ferrosilicomanganese production. The opt-imum charge mix has been derived to produce the standard grade alloy as per BIS specifications. The residue to ore blending ratio of 1:0.6 with 18% quartz addition at basi-city 0.2 has been found to yield the standard grade ferrosilicomanganese alloy with about 77% manganese recovery.
