  • Flotation of sulfide mineral species with oils
    Patent number: 7461745
    Abstract: This invention is directed to the use of non-sulfur containing compounds as collectors in the froth flotation of certain mineral sulfide and metallic compounds. These non-sulfur-containing compounds may be from natural sources, such as vegetable oils, or synthesized commercial sources. These non-sulfide collectors can be used singularly, in combinations, and in mixtures with known commercial sulfur containing collectors. These non-sulfur-containing collectors are compatible with common frothers.
    Type: Grant

  • Heavy liquids for use in separation processes
    Patent number: 6390395
    Abstract: The subject invention pertains to the use of non-toxic heavy liquids and slurries in the separation of components of ores, concentrates, residues, soils, and scrap. Specifically exemplified herein is the use of cesium and/or rubidium salts in separation processes. These salts are particularly advantageous because of their high specific gravity and solubility in water and, their low solution viscosities.
