ABSTRACT:
Method of automatically separating and cleaning silicon carbide furnace materials using magnetic separation techniques. In the method of the invention, crushed or particulate silicon carbide furnace materials are mixed with a magnetic powder. The lower grade silicon carbide particles are then separated from the first grade silicon carbide crystals using magnetic separation. Recoveries of at least 75% of the first grade silicon carbide are possible using the method of the invention. This method is also useful for the beneficiation of ores, minerals, or man-made materials.
