Известны способы флотации иеровскитсодержащпх руд, заключающиес в том, что предварительно в щелочной среде флотируют кальцит и другие минералы породы, после чего добавлением кислоты снижают рН пульпы до 4,5-6,8 и флотируют перовскит жирными кислотами, их мылами или гидроксамовыми кислотами.Known methods for flotation of ierovskite-containing ores are that calcite and other minerals of the rock are pre-floated in alkaline medium, after which the pH of the pulp is reduced to 4.5-6.8 by the addition of acid and the perovskite is floated with fatty acids, their soaps or hydroxamic acids.
Предлагаемый способ отличаетс тем, что флотацию перовскита провод т непосредственно из измельченной руды без кальцитовой флотации, что достигаетс в результате повыщени щелочности среды более 7 и применеПИЯ в качестве реагента - собирател моноэфиров ксилита типа:The proposed method is characterized in that the perovskite flotation is carried out directly from crushed ore without calcite flotation, which is achieved by increasing the alkalinity of the medium for more than 7 and using the reagent-collector of xylitol monoethers of the type:

где R - углеводородный радикал, имеющий от 10 до 16 атомов углерода. 1 Предлагаемый способ позвол ет интенсифицировать процесс флотации. Пое мет изобоетени Способ флотации перовскитсодержащих5 руд, отличающийс тем, что, с целью пр мого выделени перовскита в пенный Ф- отацию провод т в щелочной среде с применением в качестве собирател моноэфиров ксилита.where R is a hydrocarbon radical having from 10 to 16 carbon atoms. 1 The proposed method allows to intensify the flotation process. Transfer from perovskite-containing ore flotation method, characterized in that, for the purpose of direct separation of perovskite into foamy f-otation, it is carried out in an alkaline medium using xylitol monoethers as a collector.
