Abstract
Characterization and hydrometallurgical research was conducted by the Bureau of Mines to devise procedures for recovery of metals such as CO, ni, V, w, mo, cr, fe, cu, or zn from waste catalysts. The research effort was concentrated on recovery of metals from spent hydroprocessing, hydrogenation, and high-temperature shift catalysts. Results showed that 73% to 99% of the contained critical metals were extracted by a variety of processing approaches, including anhydrous chlorination, ammoniacal, acid, or caustic leaching, and na2co3 roasting followed by water leaching.
