METHOD OF PROCESSING OF ELECTRONIC AND CABLE SCRAP Russian patent published in 2008 - IPC B03B9/06 C22B7/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to dry processing of electronic and cable scrap and it can be widely used in processing of radioelectronic junk and game playing machines with separation of metals and sorting out plastics. Proposed method of processing of electronic and cable scrap consists of two stages of milling in impact mills, sieve sizing to get particles of +5 mm and -5 mm, directing +5 mm particles to second stage of milling, electrostatic separation with obtaining middlings in form of locked concretions. Then gravity separation of - 5 mm particles is carried out on concentration table and tailings, together with middlings from electrostatic separator, are directed to second stage to unlock middlings. All flow of milled and partially separated scrap is directed for magnetic separation, and nonmagnetic product, for electrostatic separation.

EFFECT: increased capacity, extraction and quality of metal concentrate, higher degree of junk cleaning from dielectric, reduced energy consumption and cost of process.
