How Is Molybdenum Mined and Processed? Refractory Metals ...

Sep 05, 2019  Molybdenum Processing. 1. Grinding. A grinding machine crushes rocks the size of footballs to the size of gravel, then uses a ball mill to further reduce the material to the size of cosmetic powder. 2. Flotation. In the flotation process, the ground ore/gangue powder is mixed with a liquid reagent and inflated.

Molybdenum Processing - IMOA

The chemical reduction of pure molybdenum trioxide or ammonium dimolybdate to metal requires two stages because conversion directly to metal releases heat that inhibits the process. The first stage reduction to MoO 2 is performed in the 450-650°C range. Molybdenum dioxide is then reduced to molybdenum metal in second stage reduction, using ...
