Abstract: The craft method of catalytic oxidation separation of high carbon nickel molybdenum was studied,and the craft condition was discussed.The best separation condition of nickel and molybdenum in the high-carbon Nickel molybdenum was identified by the single factor test:the sulfuric acid concentration was 15%,excess coefficient of pyrolusite was 20%,liquid-solid ratio was 1∶3,response time was 6 h,and reaction temperature was 95 ℃; when the mass ratio of catalyzer C and nickel is 4.4,the leaching rate could reach 95.84%,the leaching rate of molybdenum was only 3.74%,and the molybdenum mainly gathered in the residue in the form of molybdic acid.In such conditions,the preliminary separation of nickel and molybdenum was realized.

Key words: high carbon nickel molybdenum, catalytic oxidation, separation
