Document Type and Number:
Japanese Patent JP5858101
Kind Code:
B2
Abstract:
Provided is a method for producing a pellet capable of suppressing heat shock-induced crack occurrence, when nickel oxide ores are made into pellets and placed in a reducing furnace in a smelting process. In the method for producing a pellet from a nickel oxide ore, a nickel oxide ore, a binder and a carbonaceous reducing agent are mixed, the mixture is made into a lump, and then the resulting lump is subjected to a preheat treatment at a temperature of 350 °C to 600 °C. In this preheat treatment, the lump more preferably undergoes the preheat treatment at a temperature of 400 °C to 550 °C.
