Abstract: Изобретение относится преимущественно к экспериментальной биологии и физиологии. Способ включает формирование сигнала СВЧ диапазона, деление его на опорный и измерительный сигнал, излучение последнего на участок объекта, прием отраженного сигнала, промодулированного сигналом низкой частоты и выделение из опорного и отраженного сигналов результирующего сигнала с последующим определением физического параметра участка объекта, по которому судят о его состоянии. При этом для излучения сигнала используют волновод круглого сечения, загруженный набором диэлектрических вставок, причем у измерительного сигнала сдвигают фазу на угол π, а у опорного - на угол π/2, а по результирующему сигналу определяют величину комплексной диэлектрической проницаемости участка объекта. Устройство содержит генератор СВЧ, выход которого подключен к первому плечу четырехплечего трехдецибельного ответвителя, второе плечо которого сообщено с блоком измерения, третье - с волноводным трактом измерительного сигнала, а четвертое - с волноводным трактом опорного сигнала, имеющего фазовый модулятор. Оба тракта выполнены с возможностью подстройки длины пути проходящих по ним сигналов. Сдвиг фазы на π в тракте измерительного сигнала и на π/2 в тракте опорного сигнала позволяет существенно повысить точность измерения. 2 с.п. ф-лы, 1 ил.

Abstract: FIELD: methods for flotation of pentlandite from polymetallic pyrrhotine-containing materials. SUBSTANCE: method includes preliminary treatment of material pulp in lime medium with salt of dithiocarbamic acid, conditioning with sulfhydryl collector and foaming agent and stage-by-stage flotation separation of pentlandite into foam products in continuous aeration of pulp with oxygen-containing gas. Separation of pentlandite at the first stage is carried out for 24-32 min and aeration of pulp with oxygen-containing gas is effected at weight ratio of elemental oxygen, salkali salt of dithiocarbamic acid and pyrrhotine of 1:(0.02-0.11):(140-215). Oxygen-containing gas is used in the form of mixture containing 15-45 wt.-% of elemental oxygen and gases inert for the given system. Pentlandite is separated into two stages to produce two desired nickel-containing products: selective nickel concentrate sent directly by pyrrometallurgical production, and pyrrhotine concentrate processed by the known methods, for instance, by autoclave-oxidizing oxygen leaching with production of sulfide concentrate and technical sulfur. In this case oxygen-containing absorbent gas of the process of autoclave oxidizing leaching is used for pulp aeration at the first stage of flotation separation of pentlandite. EFFECT: higher efficiency. 3 cl, 1 tbl
