Известен способ получени  сульфатных калийныХ солей путем растворени  лангбейнитового концентрата, .полученного при переработке полиминеральных руд, с последующим отделением нерастворимого осадка дальнейшей переработкой образова1В шегос  щелока.A known method of producing sulphate potassium salts by dissolving the langbeinite concentrate obtained during the processing of polymineral ores, followed by the separation of the insoluble sediment by further processing of the formed Liquor Lye.

ПРИ этом отмечаетс  невозможность регенера|ЦИи кали  и магни  из эпсомитового щелока в св зи с усплепным пенообразованием при вьтарке вследствие наличи  в нем комллекса флотореагентов, используемых дл  флотадионного обогащени  нерастворимого остатка руды.At the same time, the impossibility of potassium and magnesium regenerator from epsomite liquor is not possible due to supersized foaming during flotation due to the presence of a complex of flotation reagents used for flotation of the insoluble ore residue.

Цель изобретени  - повышение степени извлечени  кали .The purpose of the invention is to increase the degree of extraction of potassium.

Паставленна  цель дости гаетс  тем, что лаиг.бейннтовый концентрат предварительно прокаливают при температуре 400-600°С. При этом происходит тер.мическое разрушение комплекса флотореагентов, что полностью рещает проблему регенерации кали  и магни  из маточных щелоков, и распад гидрослюд нормальных окислов, позвол ющий резко интенсифицировать .процессы их сгущени  и фильтрацию.The pastalenny goal is achieved by the fact that the lag.bainnt concentrate is preliminarily calcined at a temperature of 400-600 ° C. In this case, a thermal destruction of the complex of flotation reagents occurs, which completely solves the problem of the regeneration of potassium and magnesium from the mother liquors, and the decomposition of hydromica of normal oxides, which allows to sharply intensify the processes of their condensation and filtration.

Пример. 100 кг .полиминеральной руды раствор ют .в 273,19 кг маточного щелока с добавлением 51,95 кг воды и получают 313 кгExample. 100 kg of polymineral ore are dissolved. In 273.19 kg of mother liquor with the addition of 51.95 kg of water and receive 313 kg

осветленного насыщенного щелока и 59,96 к& нерастворимого остатка. Остаток флотируют и получают 19,06 кг лангбейиитового флотоконцентрата и 42,04 кг галитовых хвостов. Флотоконцентрат прокаливают при температуре 550°С 40 мин и получают 13,65 кг продукта . ,clarified saturated liquor and 59.96 k & an insoluble residue. The residue is floated to obtain 19.06 kg of langbeyite flotation concentrate and 42.04 kg of halite tailings. The flotation concentrate is calcined at a temperature of 550 ° C for 40 minutes and 13.65 kg of product is obtained. ,

ПрОкаленнь й продукт раствор ют в 32,80 кг воды ,при температуре 98°С. Оставшийс  после растворенп  гипс и окислы отдел ют отстаиванием или фильтра1Ц|Ией, а лангбейнитовый щелок направл ют на смешешю с осветленным насыщенным щелоком. Из смещанного щелока после охлаждени  получают 53,70 кг щенита и 9,42 кг сульфата кали .The galvanized product is dissolved in 32.80 kg of water at a temperature of 98 ° C. The remaining gypsum after the solution and the oxides are separated by settling or filtering 1C | Iya, and langbainite liquor is sent to the mixture with clarified saturated liquor. After cooling, 53.70 kg of pulenite and 9.42 kg of potassium sulfate are obtained from the displaced liquor.
