A Novel Technology of Molybdenum Extraction from Ni-Mo Alloy

Article Preview

Abstract:

The recovery of molybdenum from Ni-Mo alloy was investigated by acid oxidation leaching in H2SO4-NaClO3 system and then ion exchange process of leach liquor. The results in the leaching tests show that the leaching rates of nickel, molybdenum and iron are 99%, 97% and 98% respectively under the optimum conditions of H2SO4 dosage of 0.24mol per 20g Ni-Mo alloy, mass ratio of NaClO3/Ni-Mo alloy of 1.0, liquid-solid ratio of 4:1, leaching temperature of 100oC and time of 4h. The extraction of molybdenum in leach liquor was studied by ion exchange. The test results of resins selection show that the D308 resin is the best among resins on molybdenum adsorption. The results from the column tests of the D308 resin indicate that the mass ratio of Ni/Mo in effluent reaches to 10.84 from initial ratio of 0.607 and the adsorption rate of molybdenum is 94.4%.
