Abstract

1485227 Fluoride-free phosphates PENNZOIL CO 1 Oct 1975 [7 Oct 1974 29 Aug 1975] 40089/75 Heading C1A Phosphate rock is reacted at 70-95‹ C. with a solution of phosphoric acid containing alkali metal ions using sufficient phosphoric acid to solubilize completely the calcium phosphates present and sufficient alkali metal ions to cause fluorides present in the rock to precipitate as alkali metal fluosilicate and form a slurry in a solution of monocalcium phosphate and phosphoric acid, separating the solid alkali metal fluosilicate, and recovering a solution of monocalcium phosphate in phosphoric acid.
