Ф о р ) л а изобретени F o r) l inventions
1. Способ получени фосфорной .кислоты путем €Мбшепи оборотной фо1сфор«ой кислоты с фосфатным сырьем в присутствии соедине«ий латри или кали , Обработки получеи«ой пульпы л-юнОкальцийфосфата серной кислотой с кристаллизацией полутидрата сульфата калыци и фильтрации суспензии, о тличающийс тем, что, с целью снижени 1. A method of producing phosphoric acid by Mbshepi recycled phosphoric acid with a phosphate raw material in the presence of latry or potassium compounds that, in order to reduce
расхода соединений иатри или кали и увеличени Степени испо льзовали фосфатного сырь , оборотную фосфорную кислоту до ее смешени ic фосфатным сырьем и соединени ми натри или «али обрабатывают IMOHOкальциАфосфатной лульпой.the consumption of the compounds of sodium or potassium and the increase in the degree used phosphate raw materials, recycled phosphoric acid before it is mixed with phosphate raw materials and sodium compounds or "ali treated with IMOHO calcium phosphate lulpa.
2. Способ ПО П. 1, отличающийс тем, что Лчидка фаза оборотной фосфорной кислоты посл.е обработки ее .монокальцийфоофат1НОЙ ;иульпой содержит не более 0,10% сульф .ат-иона.2. The method according to claim 1, characterized in that the euphoric phase of circulating phosphoric acid after its treatment with mono-calcium phosphate; that contains no more than 0.10% sulfate-ion.
