Title: A method for producing chemical fertilizers
IPC: C05B11/06
Filed: 1961-10-05
Abstract: In a process for the production of fertilizers by acidification of rock phosphate with nitric acid and sulphuric acid, or nitric acid and a metal sulphate, or nitric acid with sulphuric acid and a metal sulphate, the viscosity of the acid slurry is reduced by increasing the crystal size of the gypsum which is formed, thus facilitating separation of the gypsum from the product.  To effect a greater crystal size some of the molten liquors before or after gypsum separation are recycled to the point of gypsum crystal propagation. The recycled liquors contain \sB20% of the calcium ion equivalent to the sulphate ion in the acid liquors.  The remaining mother liquors are separated from gypsum, ammoniated, concentrated, granulated, dried and cooled.  In examples: (1) nitric acid and sulphuric acid-filtrate being cycled; (2) nitric acid potassium sulphate-slurry being recycled; (3) nitric acid, sulphuric acid and potassium sulphate-filtrate being recycled, are exemplified.  Metal sulphates specified are potassium sulphate, ammonium sulphate, magnesium sulphate and manganese sulphate.
