CA 2176692

A process for obtaining Ni units from sulfur-bearing nickel concentrate during refining a nickel-alloyed steel or a stainless steel. Sulfur of the concentrate is transferred to and held within the slag by controlling slag composition and temperature, degree of mixing of the slag with the bath by an inert gas and aluminum level in the bath. The extent of desulfurization by the slag, the slag weight and the steel sulfur specification determine the amount of concentrate that can be added to the bath. The ratio of the slag weight to the iron bath weight should be in the range of 0.10-0.30 and the bath temperature is maintained between 1550-1700C. The slag basicity is controlled between 1.0 and 3.5, the composition of Al2O3 in the slag is maintained between 15-25 wt. % and the composition of MgO is maintained between 12-20 wt. %.
