Moly Copper and Tungsten Copper Surface Wettability. Moly and tungsten copper's infiltration requires a sintering temperature ranging from 1100-1350 °C. In this range, liquidized copper is more wettable to the tungsten surface than molybdenum. This provides a wider wetting angle for copper to penetrate the tungsten surface.
The separation of molybdenite and copper sulfide is achieved in the second stage through flotation. [8] In most scenarios, copper sulfides, such as chalcopyrite, are depressed using a depressant (e.g. NaHS, NaCN, or Nokes reagent (P 2 S 5 + NaOH)) [9] and molybdenite is recovered as a
