Abstract
Initially, a reaction stage is carried out in which the potassium chloride is put into contact with a solution of dilute nitric acid coming from a stage of recovery of the acid by re-extraction and with a solution of concentrated nitric acid, all the potassium chloride supplied being thus dissolved and avoiding any crystallization of the potassium nitrate formed in order to, subsequently, carry out a stage of separation of the insoluble impurities which accompany the potassium chloride from the reaction mixture obtained, leaving this completely clarified and free from solids. With these improvements complete separation of the insoluble impurities of the potassium chloride can be carried out immediately after the reaction stage thus producing a white potassium nitrate of high purity.
