<p>ALUMINUM PURIFICATION SYSTEM A method for extracting aluminum of substantial purity from furnace products resulting from carbothermic reduction of alumina-bearing ores and contaminated with up to about 30 weight percent of aluminum carbide is disclosed. The method involves contacting the furnace product with a high alumina containing molten slag in the substantial absence of reactive carbon, so as to cause the alumina-containing slag to react with the aluminum carbide, thereby diminishing the aluminum carbide content of the furnace product.</p> |
