  • Processing nickel bearing sulphides
    Patent number: 9028782
    Abstract: The present invention provides a method of separating nickel bearing sulphides from mined ores or concentrates of mined ores that contain talc particles is disclosed. The method comprises adjusting the Eh of a slurry of mined ores or concentrates of mined ores and making particles of nickel bearing sulphides less hydrophobic than talc particles and floating the nickel bearing sulphide particles from the slurry.
    Type: Grant
    Filed: January 9, 2009
    Date of Patent: May 12, 2015

  • Odor control
    Patent number: 8734757
    Abstract: A process for producing a mineral concentrate product that at is at least a substantially odor-free product comprises any one or more than one of (a) organics removal by (i) treatment of a froth product slurry containing floated mineral particles to remove organic compounds from the mineral particles and/or (ii) thermal treatment, and (b) addition of chemicals to prevent residual organic compounds on mineral concentrates being converted to odorous compounds, particularly while the concentrates are being stock-piled or transported.
