Abstract
Комплексный способ переработки отходов обогащения железных руд, включающий дробление отходов, отделение магнитных пород магнитными сепараторами, отделение и переработку тяжелых пород, отделение и переработку горных легких и немагнитных пород, отделение и переработку размокаемых пород, отличающийся тем, что переработку отходов производят в два этапа на первом сухом этапе производят первичное отделение магнитных пород электромагнитами сепараторами барабанного типа, разделяют на классификаторе отходы на класс крупностью +1,5 мм и передают его на дробление, где его измельчают и сбрасывают на ленточный транспортер и смешивают с классом крупностью -1,5 мм после классификатора и проводят вторичное отделение магнитных пород электромагнитами сепараторами барабанного типа магнитных пород отходов, которые направляют на переработку и брикетирование, а немагнитные породы передают на второй гидравлический этап переработки, для чего их сбрасывают в вибрационный желоб, установленный с уклоном, куда подают воду, и в созданной пульпе гравитационно разделяют немагнитные породы по плотности и крупности частиц, для чего гидравлический поток равномерно увеличивают по высоте в вибрационном желобе путем изменения его, а дифференцированный поток направляют в приемные воронки, с отводящими обезвоживающими желобами, установленными с углами естественного откоса для перепуска обезвоженной сыпучих пород в обезвоживающие бункера с питателями, откуда обезвоженные породы периодически подают в аппараты Кнельсона, в которых разделяют частицы пород на тяжелые, благородные и редкоземельные, шлихи которых отгружают для аффинаж�A complex method of processing waste of iron ore dressing, including crushing of waste, separation of magnetic rocks by magnetic separators, separation and processing of heavy rocks, separation and processing of mountain light and non-magnetic rocks, separation and processing of soaked rocks, characterized in that waste processing is performed in two stages on in the first dry stage, the primary separation of magnetic rocks is carried out by drum-type electromagnets, the waste is separated on the classifier into a size class of +1.5 mm and transferred to crushing, where it is crushed and dropped onto a belt conveyor and mixed with a size class of -1.5 mm after classifier and carry out the secondary separation of magnetic rocks by electromagnets drum-type separators of magnetic waste rocks, which are sent for processing and briquetting, and non-magnetic rocks are transferred to the second hydraulic processing stage, for which they are dumped into a vibrating chute installed with a slope, where give water, and in the created pulp non-magnetic rocks are gravitationally separated according to the density and size of particles, for which the hydraulic flow is uniformly increased in height in the vibrating chute by changing it, and the differentiated flow is directed into receiving funnels, with drainage dewatering chutes installed with the angles of repose for bypassing dewatered bulk rocks into dewatering bunkers with feeders, from where the dewatered rocks are periodically fed to Knelson's apparatus, in which rock particles are divided into heavy, noble and rare earth, the concentrates of which are shipped for refining�
