Abstract
The Bureau of Mines is investigating chlorination methods, various hydrometallurgical approaches, and pyrometallurgical roasting procedures to recover Ni, Mo, W, Cu, and Cr from spent hydroprocessing, hydrogenation, and high-temperature shift catalysts. Laboratory work to date has resulted in extraction of 73% to 99% of the metals from these wastes. Total processing schemes for recovering the metals have been proposed. Economic feasibility of the proposed processing schemes is being evaluated.
