Abstract
Procedure for the purification of the phosphoric acid obtained by wet means, by means of a chemical treatment, characterized in that the phosphoric acid of the wet method, after filtering and cooling, is treated with phosphate rock (phosphorite) finely pulverized with calcium sulfate dihydrate until obtaining a content of 1,4 ± 0.2% SO4H2, and with sodium ions from a soluble salt in the precise amount to remove fluorine and silicon anhydride with formation of sodium fluosilicate; a supersaturated suspension of solids consisting of calcium sulfate dihydrate, sodium fluosilicate and small amounts of monocalcium phosphate dihydrate is maintained for a variable time from a minimum of eight hours, by violent agitation; and finally the purified phosphoric acid and the sludge are separated, with eventual recovery of the phosphoric acid contained in them.
