Abstract
The need to meet strict pollution control regulations is providing an incentive to search for new, low-pollution scrap processing methods, and the availability of large volumes of liquid nitrogen at relatively low prices makes cryogenic processing more competitive with other processing methods on an economic basis. The Bureau of Mines has been conducting research on the use of cryogenic methods for reclaiming copper from scrap wire and in separating mixtures of nonferrous metals recovered from nonmagnetic residues from automobile shredders. Some preliminary work has also been done on cryogenic processing of automobile tires and scrap plastics.
