ABSTRACT:
Beneficiation of metallic ores selected from the group of zinc, bismuth, cobalt, nickel, titanium, zirconium, thorium, chromium, molybdenum, wolfram, and uranium, by froth flotation process using commercial amines in conjunction with oxalic acid or alkali oxalates to obtain pure concentrates of said metal values comprises; adding to a water suspension of finely divided ore of amine type collectors and an adequate amount of oxalic acid or a soluble oxalate which acting in conjunction activate and levitate in the froth by usual froth flotation process the metal values of zinc, bismuth, cobalt, nickel, titanium, zirconium, chromium, and uranium minerals; and for molybdenum and wolfram recovering the pulp of mineral slurry are oxidized with hydrogen peroxide, or any strong oxidizing agent and proceed as described above.
