METHOD OF PRODUCTION OF CLEANED COAL FOR METALLURGICAL PROCESSES AND METHOD OF PRODUCTION OF REDUCED METAL AND SLAG CONTAINING OXIDIZED NON-FERROUS METAL WITH THE USE OF THIS COAL Russian patent published in 2007 - IPC C10L9/02 C22B5/10 C21B13/00 

FIELD: cleaning of low-grade coal not suited for production of reduced metal by standard carbon-composite method.

SUBSTANCE: proposed method is based on use of cleaned coal for production of high-quality reduced metal. Coal is first kept in organic solvent simultaneously with heating, thus obtaining cleaned coal suitable for metallurgy which possesses higher thermoplasticity as compared with starting coal. Then, mixture of cleaned coal and starting material is subjected to agglomeration in agglomerator and agglomerate thus obtained is reduced at heating in furnace provided with movable hearth; then, it is molten by further heating, thus obtaining reduced melt which is cooled and hardened in furnace provided with movable hearth, thus obtaining solid material, after which reduced solid material is withdrawn from furnace. Then, slag is removed with the use of screen and reduced metal is extracted.

EFFECT: enhanced efficiency; improved quality of reduced metal.
