Abstract
Provided is a production 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 nickel oxide ore, carbonaceous reducing agent, and iron oxide; and a step S12 for forming pellets, which are agglomerates having a layered structure, by using the two or more types of mixtures such that the mixture with the highest content ratio of iron oxide, among the two or more types of mixtures forms the outermost layer.
