METHOD OF STICKING SEPARATION Russian patent published in 1996 - IPC

FIELD: manufacture of building materials. SUBSTANCE: method includes application of heated sticky coat onto working body surface, cooling of sticky coat by water, forced contacting of flooded granular material with sticky coat, withdrawal of gangue particles and separation of stuck particles of useful component from sticky coat. Application of sticky coat is carried out in its melted state by polymolecular layer on fast moving hydrophobic surface of working body. Then it is cooled by water at the direct contact of sticky coat with particles of processed material. The movement equal or approximating the movement velocity of processed material particles at its monolayer arrangement in the area of contacting with sticky coat. The preliminary contacting of processed material particles with sticky coat is carried out at their monolayer rolling between two touching between themselves flexible surfaces of working body with sticky coat at the negligible continuous offset of these surfaces one relative another. Application of sticky coat in its melted state by polymolecular layer on fast moving hydrophobic surface of working body is carried out by aerosol deposition, for example by means of sprayers in case of feeding the hot air or live steam. EFFECT: enhanced efficiency of enriching mineral resources. 1 cl
