A method for smelting reduction of Ni ore comprises charging Ni ore, carbonaceous material and flux into a converter type smelting reduction furnace holding molten iron therein and controlling a post-combustion ratio (( H2O + CO2)/( H2 + H2O + CO + CO2) ] inside the smelting reduction furnace at 0.3 or more by blowing oxygen from a top-blow oxygen lance and stirring gas from a bottom-blow tuyere arranged in the bottom of the smelting reduction furnace into the smelting reduction furnace. A relation between a content of carbon (C) (%) in molten metal and an amount of slag produced per ton of molten metal is represented with a formula: [C] S (T/HMT)/3.
