Description
Известные способы получени криолита щелочным методом требуют сложного технологического оформлени и значительных затрат.Known methods for the preparation of cryolite by the alkaline method require complex technological design and significant costs.
Предлагаемый способ более сове;1пггнеи по с завнению с известными подобными способами, так как он свободен от указанных недостатков. Это достигаетс тем, что необходимый раствор фтористого натри получают путем взаимодействи фторсиликата натри с содой в пульпе при 50-90° с последующим отделением раствора от кремнезема отстаиванием и фильтрацией. За исходное сырье при получении растворов фтористого натри берут вместо флюорита фторсиликат натри (отход суперфосфатного производства). Его обрабатывают содой в пульпе при 50- 65° (1- стади ) и 65-90° (2- стади ); необходима продолл птельность процесса обработки не превышает 1 часа. Далее пульпу разбавл ют холодной водой дл получени раствора фтористого натри необходимой концентрации.The proposed method is more common; 1yrgynea is used with known similar methods, since it is free from the indicated disadvantages. This is achieved in that the required sodium fluoride solution is obtained by reacting sodium fluorosilicate with soda in the pulp at 50-90 ° C, followed by separating the solution from silica by settling and filtering. Sodium fluorosilicate instead of fluorite is taken as raw material for the production of sodium fluoride solutions (waste of superphosphate production). It is treated with soda in the pulp at 50-65 ° (1-stage) and 65-90 ° (2-stage); the necessary continuity of the processing process does not exceed 1 hour. The pulp is then diluted with cold water to obtain a solution of sodium fluoride of the required concentration.
Замена флюорита фторсиликатом натри дл приготовлени расткоров фтористого натри сокращает производственный цикл получени криолита, упрощает аппаратурное оформление процесса и удешевл ет его стоимость.Replacing fluorite with fluorosilicate sodium to make sodium fluoride rasters shortens the production cycle of cryolite, simplifies the instrumentation of the process, and reduces its cost.
