  • Patent number: 5341938
    Abstract: A method of separating desired material from undesired material is provided. The method is performed by forming a slurry of material and introducing it into a specially designed flotation reactor chamber. A foam is generated and introduced into the reactor chamber and dispersed into the slurry. A stream of water is provided to separate the undesired portion of the material from the desired portion of the material that has adhered to the bubbles in the foam.
    Type: Grant
    Filed: May 13, 1993
    Date of Patent: August 30, 1994
    Assignee: Servicios Corporativos Frisco, S.A. de C.V.
    Inventors: Ulises M. Valenzuela, Guillermo Moguel
  • Patent number: 5266240
    Abstract: A foam flotation reactor for the separation of hydrophobic and hydrophilic products is provided. The reactor combines a material to be beneficiated, collector reagents, and a stream of specifically generated gas bubbles, in order to collect the desired product in the foam in a more efficient manner. A narrowed upper part of the reactor and accompanying water sprays force separation of undesired particles. A foam generator efficiently supplies a bubbly liquid/frothing agent to the reactor.
