A method for smelting a nickel oxide ore, wherein the reduction step progresses effectively while maintaining the strength of the pellets, comprises: a pellet production step S1 for producing pellets from a nickel oxide ore; and a reduction step S2 for reducing and heating the obtained pellets in a smelting furnace at a predetermined reduction temperature. In the pellet production step S1, a mixture is formed by mixing materials including said nickel oxide ore without mixing a carbonaceous reducing agent, and the pellets are formed by agglomerating said mixture. In the reduction step S2, in charging the obtained pellets into the smelting furnace, a carbonaceous reducing agent is spread in advance over the furnace floor of the smelting furnace and the pellets are placed on the carbonaceous reducing agent, and the pellets are reduced and heated in a state where the pellets are covered by the carbonaceous reducing agent.
A method for charging pellets for smelting by forming pellets from nickel oxide ore, and reducing and heating the pellets with a smelting furnace, the method comprising:
A method for smelting nickel oxide ore that forms pellets from nickel oxide ore and smelts by reducing and heating the pellets, the method comprising:
