STUDY OF PHOSTATIC ACID AND AMMOPHOS ACQUISITION BASED ON USED SULPHATE ACID

Of extractive phosphoric acid and ammophos based on low-quality, cheap Mazidaği (Turkey) phosphorite and waste sulfuric acid in one unit, unlike the existing technology, was developed using the results of laboratory research. The description of the process carried out according to the new technological scheme was given, the parameters of the technological regime were analyzed, and the quality indicators of the received product were determined. It was found that the proposed technological scheme allows to reduce production costs and produce better quality products.
