    摘要: An improved method and apparatus for producing ferro-alloys from ore in which an ore is first mixed with a solid reducing agent, preheated and pre-reduced in a rotary kiln, and smelted in an electric furnace, in which the pre-reduced ore is heated by a burner provided in the electric furnace where it is also reoxidized. The ore is also heated in the rotary kiln by recycled gas.
