Document Type and Number:
WIPO Patent Application WO/2017/188344
Kind Code:
A1
Abstract:
The present invention addresses the problem, in methods for producing a metal or alloy by reducing a mixture that contains an oxide ore, of providing an oxide ore smelting method with good productivity and efficiency. The present invention is an oxide ore smelting method for producing a metal or alloy by reducing a mixture that contains an oxide ore, the method comprising at least: a mixing step S1 for mixing an oxide ore with a carbonaceous reducing agent; a mixture-molding step S2 for molding the mixture obtained to obtain a mixture molding; and a reducing step S3 for heating the mixture molding obtained at a specified reducing temperature in a reducing furnace.
