ABSTRACT:
A froth flotation method for recovering vanadium, molybdenum, wolfram, and uranium minerals over silica, alumino, and ferromagnesian silicates, which comprises; subjecting the comminuted ore of aforesaid metals to froth flotation process in the presence of phosphoric, pyrophosphoric, phosphorous, and hypophosphorous acids and an effective amount of quaternary ammonium hydroxide; molybdenum sulfide ore is oxidized with hydrogen peroxide or the like peroxidizing agents to a higher oxidizing state prior to adding phosphoric acid and the quaternary ammonium hydroxide; the indicated compounds provide selectivity and recovery of metal values of vanadium, molybdenum, wolfram, and uranium.
