METHOD OF ORE DRESSING BY MEANS OF SOLID HYDROPHOBIC SURFACES Russian patent published in 2013 - IPC C22B1/00 B03B5/28 B03B7/00 

FIELD: metallurgy.

SUBSTANCE: method includes the following stages. (A) Production of sludge or dispersion of a mixture, which is subject to processing in at least one dispersion medium. (B) Bringing in contact the sludge or dispersion from the stage (A) with at least one solid hydrophobic surface for binding with the latter of at least one hydrophobic substance to be released, in which the solid hydrophobic surface is a surface of the inner wall of the pipe, the surface of the plate, the surface of the conveyor belt or the surface of the inner wall of the reactor. (C) Removal of at least one solid hydrophobic surface, with which at least one hydrophobic substance is bound, from the stage (B), out of the sludge or dispersion, in which at least one hydrophilic substance is contained. (D) Removal of at least one hydrophobic substance from the solid hydrophobic surface.

EFFECT: invention will make it possible to efficiently and with high extent of purity separate hydrophobic substances from a mixture, which contains these hydrophobic and also hydrophilic substances with no necessity in connection of magnetic particles to hydrophobic components to be separated and necessity in using air flow.
