Abstract
Leaching of molybdenum from molybdenum concentrate using sodium hydroxide was studied.The effects of leaching temperature,time,particle size of molybdenum concentrate,stirring speed and coefficient β(the mass ratio of sodium hydroxide to molybdenum concentrate),ratio of solid to liquid on leaching of molybdenum were examined.The optimum technological parameters were determined.The leaching of molybdenum was 99.76% under the oplimum conditions of 85 ℃ and stirring speed of 450 r/min for 90 min,particle size of-0.1 mm,solid/liquid ratio of 1∶4 g/mL and the coefficient β of 1.2.
