Abstract
A process for the production of mixtures of potassium phosphate dihydrogen/potassium nitrate by reaction of phosphorite with nitric acid and subsequent reaction of the mass produced with potassium acid sulfate or potassium bisulfate, the calcium of the reaction by sulphate being approximately stoichiometrically balanced and the concentrations of potassium sulfate and acid in order to obtain calcium sulfate in a filterable form, and separation of the calcium sulfate formed to give a solution containing potassium nitrate and potassium dihydrogen phosphate.
