METHOD FOR PRODUCTION OF PHOSPHORIC ACID Russian patent published in 1997 - IPC

Abstract RU 2074112 C1

FIELD: technology of processing of phosphoric slurry formed in production of phosphorus by electrothermal method. SUBSTANCE: method includes melting of slurry, heating of molten slurry up to phosphorus content of 60-90%, and supply for burning of slurry with mineral part-phosphorus ratio of 0.11-0.3 with subsequent hydration. Provision of production of phosphoric acid with suspended matter amounts to less than 0.05%. EFFECT: higher efficiency. 1 tbl
