The Rolla Metallurgy Research Center has developed a new method for recycling cemented-carbide scrap. This method involves the alloying of zinc with cobalt binder. The zinc is then distilled from the carbide scrap leaving a porous mass of carbides and cobalt which can be totally reground and recycled. The Bureau of Mines' process can be used to recovery costly components in the scrap that are presently being discarded. Since the annual sales of cemented- carbides are approximately $250 million, a great economic potential exists for augmenting conservation of resources by recycling of the cemented-carbide scrap.
