Изобретение относитс к области химической технологии получени фторидов щелочноземельных элементов. В частности к процессам получени фтористого кальци из растворов фтористого а1«1мони , которые могут быть, в свою очередь, получены при утилиЗсщии фтора, выдел емого при производстве фосфорных удобрений или в других процессах.The invention relates to the field of chemical technology for the preparation of alkaline-earth fluorides. In particular, to processes for obtaining calcium fluoride from solutions of fluoride a1 ' monmonium, which can, in turn, be obtained by utilizing fluorine released during the production of phosphate fertilizers or in other processes.
Известен способ получени фтористого кальци путем взаимодействи раствора фторида аммони или щелочного фторида с известковым молоком, известью или карбонатом кальци при температуре не выше 40-С с последующим фильтрованием, промывкой и сушкой полученного осадка фтористого кальци tl .A known method of producing calcium fluoride by reacting a solution of ammonium fluoride or alkaline fluoride with lime milk, lime or calcium carbonate at a temperature not higher than 40 ° C, followed by filtration, washing and drying the resulting calcium fluoride precipitate tl.
Недостатком известного способа вл етс невысока скорость фильтрации - 270 кг/м час.The disadvantage of this method is low filtration rate - 270 kg / m per hour.
Наиболее близким по технической сущности и достигаемому результату вл етс способ получени фтористого кальци путем взаимодействи раствора фторида аммони с твердым карбонатом кальци с размером частиц i 30 мк ( мк) при температуре 80-95С с последующим добавлением к полученной пульпе олеиновой кислоты с целью ускорени осс1ждени и фильтрации тонкодисперсного осадка фтористого кгшьци . Осадок отфильтровывают,The closest in technical essence and the achieved result is a method of producing calcium fluoride by reacting ammonium fluoride solution with solid calcium carbonate with a particle size of i 30 microns (µm) at a temperature of 80-95 ° C, followed by adding oleic acid to the resulting pulp to accelerate precipitation and filtration of fine sediment fluoride. The precipitate is filtered off.
Скорость фильтрапромывают и сушат The speed is filtered and dried.

Поставленна цель достигаетс описываемом способом получени фтористого кальци , заключающемс во взаимодействии раствора фторида ам0 мони с твердым карбонатом кальци , который берут с размером частиц 302000 мкм при температуре 80-95 0 с последующей фильтрацией, прокывкой и сушкой полученного осадка фторис5 того кальци .This goal is achieved by the described method of producing calcium fluoride, which consists in the interaction of ammonium fluoride solution with solid calcium carbonate, which is taken with a particle size of 302,000 µm at a temperature of 80-95 0, followed by filtration, sintering and drying of the obtained calcium fluoride precipitate.
Отличительным признаком способа вл етс то, что карбонат кгшьци берут с размером частиц 30-2000 мк.A distinctive feature of the method is that carbon carbonate is taken with a particle size of 30-2000 microns.
Если брать карбонат кальци с размером частиц мк и 2000 мк:If you take calcium carbonate with a particle size of microns and 2000 microns:
