Detailed Description
The current situation of the domestic molybdenum ore processing equipment:
Molybdenum ore dressing has been half a century of history,molybdenum ore processing plant from the old China only molybdenum processing plant development up to now more than 50 molybdenum processing plant, copper molybdenum processing plant, tungsten and molybdenum processing plant and molybdenum bismuth electionfactory production of molybdenum concentrate. Molybdenum ore processing technology gap with foreign advanced countries have been getting smaller and smaller.
Molybdenum ore processing plant from some of colored system point of view, the processing of ore grade vary greatly, the high at 0.3% or more, a low of 0.1% or less, and some only 0.02%. Processing the actual recovery of the vast majority of more than 80%. The resulting concentrate grade of 45% to 54%, tailings grade of 0.02%, a high of 0.04%, a low of 0.01%.
The current industrial production of molybdenum molybdenite concentrate smelting oxidizing roasting to extract pure molybdenum trioxide restore roasting molybdenum metal powder three links.
Molybdenum concentrate first reverberatory furnace, multiple hearth furnace roaster oxidizing roasting or flash furnace desulfurization made a calcine impure molybdenum trioxide (Mo 40% ~ 48%), Calcine using The metal thermal or silicon thermal method can produce molybdenum ferroalloy.
