  • Formation of tungsten monocarbide from a molten tungstate-halide phase by gas sparging
    Patent number: 4489044
    Abstract: Tungsten monocarbide is prepared by sparging a molten composition comprising an alkali metal halide and an oxygen compound of tungsten with a gas comprising a gaseous hydrocarbon, particularly methane.
    Type: Grant
    Filed: January 27, 1984
    Date of Patent: December 18, 1984
    Assignee: The United States of America as represented by the Secretary of the Interior

  • Selective recovery of base metals and precious metals from ores
    Patent number: 4442072
    Abstract: Metal values are recovered from ore concentrates by forming a sulfide matte, grindng the matte, leaching with sulfuric acid at elevated temperature to selectively extract nickel and iron, and roasting and leaching the residue with dilute sulfuric acid to selectively extract copper. The residue contains a high concentration of platinum, palladium and gold.
    Type: Grant
    Filed: October 20, 1982
    Date of Patent: April 10, 1984
