Aug 01 2008 Using this process molybdenum oxide could be up-graded up to 80 with 99.50 recovery of molybdenum. The required composition of molybdenum oxide 80 Mo and copper less than 0.50 was obtained by the leaching of impurities from the roasted molybdenite concentrate molybdenum oxide with 1.5 H 2 SO 4 maintaining the SL ratio 1 at 22 C
