Title: Compound fertilizer and gypsum simultaneous prodn - by digesting raw phosphate with nitric acid and tempering at elevated temp
Inventor: BOOS WILHELM DR PHIL
IPC: C04B11/26
Filed: 1973-12-19
Abstract: Compound fertilizers and gypsum are produced simultaneously by digesting raw phosphate (e.g. Florida pebble phosphate) with >7.0 mol. HNO3 per mol. P2O5, tempering the digestion solution for is not 1 hr. (perf. 2-10 hrs.) at between 50 degrees C and the b. pt. of the soln. (pref. at 60-90 degrees C), precipitating gypsum by adding soluble sulphates and/or bisulphates and/or H2SO4, and converting the gypsum-free filtrate into compound fertilizers in a conventional manner. At relatively little extra expense compared with known processes, the new procedure yields white gypsum which can readily be converted into a form suitable for building purposes. Preferably, after the separation of the gypsum, the filtrate is used for the digestion of a further quantity of raw phosphate. Raw phosphate (less impure than the initial starting material) may also be added to the digestion soln. before precipitation of the gypsum. After addition of raw phosphate to the filtrate after separation of the gypsum, tempering of the soln. is not essential before precipitation of further gypsum. Additional raw phosphate may also be introduced after precipitation but before removal of gypsum.
