Abstract

See full text

Provided is a method for smelling nickel oxide ore by which the occurrence of cracking due to heat shock can be suppressed when nickel oxide ore is pelletized and charged into a smelting step (reduction step). A method for smelting nickel oxide ore according to the present invention uses pellets of nickel oxide ore, the method being characterized by comprising a pellet production step S1 for producing pellets from nickel oxide ore, and a reduction step S2 for heating the resulting pellets at a predetermined reduction temperature in a reduction furnace, the reduction step S2 comprising preheating the pellets obtained in the pellet production step S1 to a temperature of 350 to 600°C in the reduction furnace and thereafter charging the pellets into the reduction furnace and raising the temperature of the reduction furnace to the reduction temperature.
