  • COLLECTORS FOR FLOTATION OF MOLYBDENUM-CONTAINING ORES
    Publication number: 20120145605
    Abstract: The invention is directed to the use of non-sulfur containing compounds and their derivatives as collectors in the froth flotation of particular mineral sulfide and metallic compounds, particularly molybdenum-containing compounds. The non-sulfur containing compounds and their derivatives may be from a natural source or synthetic. The non-sulfur containing compounds are typically compatible with common frothers. The non-sulfur containing compounds may be used singularly, with one or more derivatives, or in any combination with each other and/or known commercial sulfur containing collectors.

  • 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.

  • Methods for leaching of ores
    Publication number: 20030075021
    Abstract: Disclosed and claimed are efficient methods for leaching minerals from ores using an acidic solution such as sulfuric acid. Additional factors which can improve mineral recovery include the use of an alkali metal halide, grinding the ore, addition of a carbon source, and/or adjustment of the temperature at which the process is carried out. Minerals such as titanium, iron, nickel, colbalt, silver and gold may be recovered by the methods of the present invention.

  • 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.
