Abstract
1506323 Phosphoric acid; phosphates; fertilizers PRZEDSIEBIORSTWO PROJEKTOWANIA I DOSTAW KOMPLETNYCH OBIEKTOW PRZEMYSLOWYCH «CHEMADEX» 29 Jan 1976 [6 March 1975] 03622/76 Heading C1A The solution obtained by treating phosphate rock with (molar ratio 0À7 to 1À0) is divided into two parts; one part (up to 30% of the solution) is cooled and treated with 0À8 to 1À6 volumes of a water-miscible organic solvent to precipitate ammonium sulphate, and the latter and a potassium salt are added to the second part, the mixture being evaporated to dryness to provide a fertilizer. The filtrate of the first part is distilled to remove organic solvent, which is recycled, leaving H 3 PO 4 ; or is neutralized with ammonia or an alkali metal carbonate or hydroxide to precipitate the corresponding phosphate, the remaining solution being distilled to remove organic solvent for recycle.
