Abstract

Metals are formed from metal oxides in a shaft furnace, by reduction using powdered carbon in pellets, such pellets also including additional powdered carbon for combustion under controlled conditions in the presence of air to form CO2 in the combustion zone to achieve the temperature required in the lower part of the shaft furnace for the reduction reaction and to form molten metal and slag.
