Provided is a pellet production method that, in pelletizing and smelting a nickel oxide ore and producing ferronickel which is an iron-nickel alloy: makes the smelting reaction proceed effectively; increases the Ni content in the obtained ferronickel; and can prevent the ferronickel obtained after the smelting reaction from becoming granular. This pellet production method is a method for producing pellets that are used for producing an iron-nickel alloy and that are produced by mixing at least a nickel oxide ore, a carbonaceous reducing agent, and an iron oxide and agglomerating the obtained mixtures, the method comprising: a step S11 for producing at least two types of mixtures having different mixing ratios of said nickel oxide ore, said carbonaceous reducing agent, and said iron oxide; and a step S12 for forming pellets, which are agglomerates having a layered structure, by using said two or more types of mixtures such that the mixture with the highest content ratio of said iron oxide, among said two or more types of mixtures that have been obtained, forms the outermost layer. |
