Abstract
Discussed is the INMETCO processing of electric arc furnace (EAF) baghouse dusts from the specialty-steel and low-alloy industries. In addition, the INMETCO process has been modified to recover nickel, chromium and iron from many other waste materials including:
-
pickling solutions or filter cakes
-
spent nickel and chromium plating baths
-
carbon refractories from pickling tanks, and
-
superalloy wastes including baghouse bags.
INMETCO is the only North American company presently capable of recycling nickel-cadmium batteries by high-temperature metals recovery. This process and the details of INMETCO’s best demonstrated available technology (BDAT) test program are discussed.
