<p>A method is provided for producing molten metal consisting mainly of manganese and iron. The method comprises the steps of injecting a pulverulent material, containing manganese oxide, directly into a smelting reduction zone, together with coal and/or hydrocarbons, in powder form. The smelting reduction zone is continuously produced by the supply of heat energy e.g. from a plasma generator in a shaft filled with solid reducing agent. Examples include the production of ferromanganese and ferrosilicon manganese.</p> |
