The engineered collection medium has a 1-1 solid phase body configured with a three-dimensioml open-cell structure like foam or sponge to provide collection smfaces. The three-dimensioml 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 smfaces 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.
