FIELD: mining.SUBSTANCE: invention relates to mining industry and diamond processing industry. Device for separating fractions contains a loading bunker that is connected with mechanical crushing device of large units connected to upper section of the box with attached metal activator in the form of a high voltage source, vessel for receiving fractions. Box is located vertically and is equipped with two additional sections. One section has an activator of nonmagnetic metals in the form of a high voltage source attached to it, and the other - an activator of silicon carbide in the form of a high voltage source. Lower parts of each section have openings and a separating element to separate appropriate fractions located opposite the opening on the side of the box. Upper section of the separating element is a magnet for magnetic separation of metal, middle section is an electrode for removal of non-magnetic metal, and bottom section is a magnet and electrode for separation of silicon carbide or rock.EFFECT: improvement of technological process, extraction of diamonds from wastes of diamond production.1 cl, 1 dwg |
