A caustic leach dezincing process is being developed for upgrading galvanized stamping plant scrap into clean scrap with recovery of the zinc. With further development the technology could also process galvanized scrap from obsolete automobiles. This paper will review: (1) the status of recent pilot plant operations in East Chicago, Indiana and plans for a commercial demonstration facility with a dezincing capacity of up to 250,000 tonnes/year, (2) the economics of caustic dezincing, and (3) benefits of decreased cost of environmental compliance, raw material savings, and improved operations with use of dezinced scrap.
