The method comprises the steps of burning the gases in a combustion chamber to remove impurities therefrom, conducting a first portion of the combustion products to a container of scrap metal, contacting the scrap metal with the combustion products for preheating the scrap metal whereby additional impurities are generated, washing in a wet scrubber the mixture of combustion products and additional impurities, mixing the scrubbed combustion products and additional impurities with a second portion of the combustion products from the combustion chamber, and removing particulates from the mixture.

Abstract: Low grade ores, such as low-grade manganese ore, are reduced in an electric smelting furnace having two melting zones divided by a barrier. The ore and a small quantity of carbon are melted in the first zone at a temperature sufficient to reduce the iron oxide contained in the ore to molten iron, leaving molten layers of ore and slag which are richer in manganese than the starting material. The melt and slag are allowed to flow over the barrier to the second zone where a second charge of ore and a greater amount of carbon are deposited. Electrode melting in the second zone is carried out at a higher temperature to reduce the manganese and remaining iron therein to form a high-grade ferromanganese product. The molten products are tapped from the furnace in the respective zones. The method of the present invention may be used with other ores such as low grade chromium ore and the method may also be used for the production of silicomanganese.
