There is provided a method of producing a partially reduced product from finely divided metal oxide containing material. The product is suited for continued reduction and the material containing the metal oxide may be an ore concentrate or an oxidic intermediate product. The material is charged to the top of a metallurgic shaft and is contacted during its fall through the shaft with hot gases of combustion, so as to melt said material. At the same time, a carbonaceous or carbon-containing reductant is charged to the furnace, such that said molten material is converted into a partially reduced product containing solid carbon material.
