Publication number: 20210379603Abstract: An engineered collection medium for use in mineral separation is described. The engineered collection medium has a solid phase body configured with a three-dimensional open-cell structure like foam or sponge to provide collection surfaces. The three-dimensional surface structure is made of a hydrophobic material which is a reaction product of isocyanate and polyol promotes the attraction of mineral particles to the collection surfaces as a hydrophobic foam. The hydrophobic foam can be in the form of a cube, sphere, or sheet and can be used in a filter or conveyor belt in a processor.Type: ApplicationFiled: February 7, 2019Publication date: December 9, 2021Inventors: Paul J.

Patent number: 9943860Abstract: An apparatus and method for collecting mineral particles in the tailings is disclosed. The apparatus may take the form of a filter, a conveyor belt, a collection plate or an impeller configured to contact with tailings of a flotation process, before and/or after the tailings are discharged into a pond. The filter, conveyor belt, collection plate or impeller has a collection area or surface made of, or coated with, a synthetic material having a functional group, e.g., having an ionizing bond to attract the mineral particles of interest. Alternatively, the synthetic material has hydrophobic molecules to render the collection area hydrophobic. When the mineral particles of interest in the tailings are combined with collector molecules, the mineral particles of interest may also become hydrophobic. The hydrophobic mineral particles of interest are attracted to the hydrophobic collection area or surface.Type: GrantFiled: May 25, 2012Date of Patent: April 17, 2018Assignee: CiDRA Corporate Services Inc.Inventors: Paul J.
