Claims (3)

1. Способ и устройство цианистого выщелачивания благородных металлов из руд, концентратов, техногенных и минеральных отходов, отличающиеся тем, что ускоренный процесс отрыва прочно- и рыхлосвязанных слоев, максимально насыщенных полезным компонентом, от поверхности минеральной частицы (твердого тела) и их растворение в общем объеме выщелачивающего раствора осуществляется напорной струей гидроэлеватора (эжектора) при перекачивании пульпы из одной емкости в другую, а необходимая аэрация растворов кислородом осуществляется эжектированием и растворением воздуха в напорной струе гидроэлеватора, работающего в "холостом" режиме, которая активно перемешивая пульпу во второй емкости создает условия для контакта твердой частицы с ионами СN- и молекулами растворенного кислорода, что значительно ускоряет образование двойного слоя вновь.1. The method and device for cyanide leaching of precious metals from ores, concentrates, industrial and mineral waste, characterized in that the accelerated process of separation of firmly and loosely bound layers, as saturated as possible with a useful component, from the surface of the mineral particle (solid) and their dissolution in general the volume of leach solution is carried out by a pressure jet of a hydraulic elevator (ejector) when pumping pulp from one tank to another, and the necessary aeration of solutions with oxygen is carried out by ejection and dissolving it in the air jet pressure hydraulic elevator operating in the "idle" mode, which actively stirring the pulp in the second container creates conditions for the contact of solid particles with ions of CN - and molecules of dissolved oxygen, which greatly accelerates the formation of a double layer again. 2. Устройство, отличающееся тем, что для улучшения доставки выщелачиваемого материала к всасу гидроэлеватора и улучшения перемешивания в жидкой и воздушной фазах и растворения воздуха в выщелачивающем растворе в насадках гидроэлеватора сделаны дополнительные отверстия, просверленные перпендикулярно к его внешней конической поверхности. 2. Device, characterized in that in order to improve the delivery of leachable material to the suction of the elevator and to improve mixing in the liquid and air phases and to dissolve the air in the leach solution, additional holes are made in the nozzles of the elevator, drilled perpendicular to its outer conical surface. 3. Устройство по п.2, отличающееся тем, что в нем отсутствуют трущиеся, вращающиеся детали, дополнительное оборудование в виде компрессоров, диспергаторов, аэролифтов, механических мешалок, сосудов, работающих под давлением и высокой температурой выщелачивающего реагента. 3. The device according to claim 2, characterized in that it does not have rubbing, rotating parts, additional equipment in the form of compressors, dispersants, aerial lifts, mechanical stirrers, vessels operating under pressure and high temperature of the leaching reagent.
