Abstract

Provided is a method for producing pellets by which, when nickel oxide ore is being pelletized and smelted to produce ferronickel, which is an iron-nickel alloy, it is possible to allow the smelting reaction to proceed effectively. A method for producing pellets according to the present invention is for producing pellets which are used in producing iron-nickel alloy and which are produced by mixing raw materials including nickel oxide ore and agglomerating the resulting mixture, wherein the method comprises: a mixing step Sfor mixing at least nickel oxide ore, a carbonaceous reducing agent, and iron oxide to generate a mixture; and a pellet formation step Sfor agglomerating the resulting mixture and forming pellets. In the mixing step S, the mixture is generated such that the total weight of nickel and iron accounts for 30 wt % or more of the total weight of the pellets formed.
