  • Method and apparatus for liquid/solid separation such as dewatering particulate solids and agitation leaching
    Patent number: 11344823
    Abstract: Methods and apparatus for liquid/solid separation for use in applications such as dewatering fine particulate solids, and recovery of valuable metals from ore in a leaching process are provided. One application relates to methods of agitation leaching of metals such as gold from gold-bearing feedstock. A slurry is formed in a tank by agitation, and allowed to settle. A filter bed forms to drain the liquid from the tank, and a vertical screen pipe such as a well point addresses the formation of an impervious film on the upper surface of the filter bed.
    Type: Grant
    Filed: October 31, 2018
    Date of Patent: May 31, 2022
    Assignee: SEPRO MINERAL SYSTEMS CORP.
    Inventors: Steven Alexander McAlister, Mark Donald Van Kleek, Michael Charles Jillings, Brennan James Mallory, Mark Henry Vinchoff
