Publication number: 20120145605Abstract: 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.Type: ApplicationFiled: December 9, 2010Publication date: June 14, 2012Inventors: Michael G. Greene, Kathleen (Bauer) Walton, Peter A. Dimas, Debbie G. Laney, Sharon K. Young, Tom L. Young, Sharon K. Young, Norman R. Reber, Norman R. Reber, JR.

Patent number: 7461745Abstract: 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: GrantFiled: October 26, 2004Date of Patent: December 9, 2008Assignee: Nalco CompanyInventors: Tom L. Young, Michael G. Greene, Kathy Bauer, Bonnie J. Reber, legal representative, Sharon K. Young, Norman R. Reber

Patent number: 6390395Abstract: 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.Type: GrantFiled: December 16, 1999Date of Patent: May 21, 2002Assignee: Versitech, Inc.Inventors: Tom L. Young, Kathy Bauer, Michael G. Greene, Sharon K. Young

Patent number: 6123788Abstract: This invention relates to copper wire having a substantially uniform unoriented grain structure that is essentially columnar grain free. This invention also relates to a process for making copper wire comprising: cutting copper foil to form at least one strand of copper wire, said copper foil being an annealable electrodeposited copper foil having a substantially uniform unoriented grain structure that is essentially columnar grain free, said foil being characterized by a fatigue ductility of at least about 25% after being annealed at 177.degree. C. for 15 minutes; and shaping said strand of wire to provide said strand with desired cross-sectional shape and size.Type: GrantFiled: May 24, 1996Date of Patent: September 26, 2000Assignee: Electrocopper Products LimitedInventors: Sidney J. Clouser, Rudolf Wiechmann, Bernd Schneider, Ulrike Bohmler, R. Duane Apperson, Robert J. Fedor, Sharon K. Young, Roger N. Wright, Stephen J. Kohut, Susan S. Enos

Patent number: 5820653Abstract: This invention relates to a process for making a shaped copper article directly from a copper-bearing material, comprising: (A) contacting said copper-bearing material with an effective amount of at least one aqueous leaching solution to dissolve copper ions into said leaching solution and form a copper-rich aqueous leaching solution; (B) contacting said copper-rich aqueous leaching solution with an effective amount of at least one water-insoluble extractant to transfer copper ions from said copper-rich aqueous leaching solution to said extractant to form a copper-rich extractant and a copper-depleted aqueous leaching solution; (C) separating said copper-rich extractant from said copper-depleted aqueous leaching solution; (D) contacting said copper-rich extractant with an effective amount of at least one aqueous stripping solution to transfer copper ions from said extractant to said stripping solution to form a copper-rich stripping solution and a copper-depleted extractant; (E) separating said copper-rich stType: GrantFiled: April 18, 1996Date of Patent: October 13, 1998Assignee: ElectroCopper Products LimitedInventors: Michael A.

Patent number: 5679232Abstract: This invention relates to a process for making metal wire, comprising: (A) forming metal foil; (B) cutting said foil to form at least one strand of metal wire; and (C) shaping said strand of wire to provide said strand with desired cross-sectional shape and size. This process is particularly suitable for making copper wire, especially copper wire having a very thin diameter (e.g., about 0.0002 to about 0.02 inch).Type: GrantFiled: April 18, 1996Date of Patent: October 21, 1997Assignee: ElectroCopper Products LimitedInventors: Robert J. Fedor, Peter Peckham, Sharon K. Young, Michael A. Eamon, Roger N. Wright, Stephen J. Kohut, Craig J. Hasegawa, Susan S. Enos, Robert D. DeWitt

Patent number: 5622615Abstract: A sulfur dioxide free process for the production of high purity metallic copper from copper-matte wherein copper-matte is leached under oxidizing conditions in a ferric-containing acid copper sulfate electrolyte leach assembly including one or more leach reactors to yield a copper-rich electrolyte, and copper cathode is produced in an electrowinning assembly which is physically decoupled from the leaching assembly and may include one or more electrowinning cells. The process operates at ambient pressure and temperatures less than the boiling point.Type: GrantFiled: January 4, 1996Date of Patent: April 22, 1997Assignee: The University of British ColumbiaInventors: Sharon K. Young, David B. Dreisinger, Jinxing Ji
