FIELD: mining. ^ SUBSTANCE: invention refers to mineral resource industry and may be used for extraction of valuable elements from ore minerals and products of their processing, for extraction of sulphides of copper, nickel, iron and precious metals from old tails of preserved tailing dump. Dressing module includes open-pit field, dredger, fixed screen, five-jet pulp-divider connected to vibrating screen with size of sieve meshes 1.5 mm, pumps for direction of minus material of vibrating screen to banks of hydraulic cyclones, pump installed at sands output from hydraulic cyclone and connected to five-jet pulp-divider and then with centrifugal separators, chamber flotation machines in process of rougher flotation of centrifugal separators tails and in process of aftertreatment. It is provided with one or two additional dredgers, onshore pumping plant with vibrating screen installed in it with size of sieve meshes 12 mm, dib-hole with overflow pocket connected by means of gravity hydraulic transport to open-pit field for tails wash-out, additional five-jet pulp-divider connected to additional vibrating screens with size of sieve meshes 1.5 mm and dib-holes for reception of minus material of mentioned vibrating screens and direction to banks of hydraulic cyclones by pumps, conditioning tanks one of which is connected by its inlet by means of gravity hydraulic transport to centrifugal separators and by its outlet with dib-hole and pump with controlled capacity - to chamber flotation machine of rougher flotation designed mechanical and consisting of 5 chambers 130 m3 each, powered in sequence, which concentrate yield is connected, by means of dib-hole and pump with controlled capacity, to other conditioning tank and then to chamber flotation machine of first aftertreatment procedure designed mechanical-air and consisting of 4 chambers 17 m3 each, powered in sequence, which concentrate yield is connected to dib-hole and pump with controlled capacity and then to chamber flotation machine of second aftertreatment procedure designed mechanical-air and consisting of 3 chambers 8 m3 each, powered in sequence, which concentrate yield and concentrate yield of centrifugal separators are connected by dib-hole-mixer to high-pressure pump, at that yield of tails of second aftertreatment is connected by means of gravity hydraulic transport to first chamber of first aftertreatment and yield of tails of first aftertreatment is connected by dib-hole and pump to first chamber of mechanical flotation machine of rougher flotation. ^ EFFECT: enhancement of yield and quality of concentrates and reduction of loss of valuable elements in flotation tails. ^ 1 dwg |
