Title:
OPEN-NETWORK FOAM OF HYDROPHOBIC MATERIAL FOR SELECTIVE SEPARATION OF MINERAL PARTICLES
Document Type and Number:
WIPO Patent Application WO/2019/157147
Kind Code:
A8
Abstract:
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.
