Abstract
Provided is a smelting method whereby reduction by a carbonaceous reducing agent is performed to obtain a reduced substance using as a raw material a nickel oxide ore or other metal oxide containing oxidized nickel or the like, for example, wherein a high-quality reduced substance can be obtained with high efficiency. The method for smelting a metal oxide pertaining to the present invention comprises reducing a mixture obtained by mixing a metal oxide and a carbonaceous reducing agent in a reducing furnace, wherein the mixture obtained by mixing a metal oxide and a carbonaceous reducing agent is heated and reduced on a floor covering material composed of one or more types of materials selected from alumina, alumina cement, magnesia, magnesia cement, zirconia, zirconia cement, and mullite.
