Description
Лиспсрсныи сртористь;й кальции с прнмесью кремнекислолЫ, который прн постепеьиой разгрузке башнп (с соответствующей догрузкой свежего известн ка) отдел ют от ненрореагировавыего KyciKOBCio 1из вестн ка, 1анр1имер, путем отсева. При этом известн к можно орошат1 водоГг. Получение плавикового шпата из отходов суперфосфатных заводов осуществл ют путем взаимодействи водного раствора кремнефториетоводородной кислоты с известн ком или известью. В этом случае процесе ведут в реакторе с мешалкой. Образовавшуюс суспензию тве)дого ф.торкальци спускают в отстокиик-декантатор. отдел ют жидк}.ю фазу со взвещеиным в ие/i шлаком от осадка плавикового шпата и направл ют последний на нодсушку.Liquids are calcium, with silicic acid mixtures, which are gradually unloading the towers (with the corresponding additional loading of fresh limestone) and are separated from the unreacted KyciKOBCio 1 limestone, by means of screening. In this case, it is known that water can be irrigated. The production of fluorspar from waste products of superphosphate plants is carried out by the interaction of an aqueous solution of hydrofluoric hydrofluoric acid with limestone or lime. In this case, the process is carried out in a stirred tank reactor. The resulting suspension of twa tf. F.calcium is discharged into a decanter-decanter. the liquid phase with the slag is separated from slag from the fluorspar precipitate and sent to the nodusku.
Подсушку производ т во врапипопднхс сушилках. Так как влажпост ,з получаемого плавикового шпата неведпка и при температуре гре о;дих дымовьь: газов он не разлат-аегс , его можно производить нуте.м неносредственного обогрева газами даже пр мо.тохом.Drying is done in wipe-dryers. Since the wetting of the fluorspar produced is not known at the temperature of the heat; smoke is smoke: it does not dissolve the gases, it can be produced directly by heating gases even directly.

Предмет изобретени Subject invention
Способ получени синтетического плавикового шпата, отличающийс тем, что, с целью увеличени ресурсов плавикового шпата, отходы суперфосфатных заводов, которые содержат четырехфтористый кремний или кремнефтористоводородную кислоту, привод т во взаимодействие с кусковым известн ком или известью в аппаратах извест;ных типов, например, в башне или реа:кторе.A method for producing synthetic fluorspar, characterized in that, in order to increase the fluorspar resources, waste from superphosphate plants that contain silicon tetrafluoride or fluorosilicic acid, is brought into contact with lumpy limestone or lime in apparatus of known types, for example, Tower or Rea: whore.
