Title:
METHOD FOR PRODUCING PELLETS AND METHOD FOR PRODUCING IRON-NICKEL ALLOY
Document Type and Number:
WIPO Patent Application WO/2016/017348
Kind Code:
A1
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 and to prevent the ferronickel obtained after the smelting reaction from becoming small in size. 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 S11 for mixing at least nickel oxide ore, a carbonaceous reducing agent, and iron oxide to generate a mixture; and a pellet formation step S12 for agglomerating the resulting mixture and forming pellets. In the mixing step S11, 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.
