Jan 31, 2012Recovery of Mo from Chilean copper slag is quite attractive to secure a stable Mo supply. The feasibility of the recovery of Mo from Cu slag as Fe-Mo alloys by carbon reduction is investigated in the present work. Mo in Cu slag is found to be fully recovered as Fe rich alloy. The recovered Fe rich alloy contains about 0.65mass% Mo and 2.4 mass% Cu.
