Abstract

The recovery of Mo from spent lubricant by applying high temperature reduction process was investigated. Suitable amounts of lime and ferrous oxide were added to the spent lubricant and the mixtures were reduced by carbon at 1773K. The reaction mechanisms of CaCO₃-MoS₂-C, CaCO ₃-MoS₂-Fe₂O₃-C and spent lubricant-CaCO₃-Fe₃O₄-C mixtures were investigated. Mo in spent lubricant was found to be fully recovered as Fe rich alloy. The recovered Fe rich alloy contained about 40mass% Mo and 4.3 mass% C. Thus, Mo recovery from the spent lubricant by carbon in the high temperature process is promising.
