Objective.The aim of the research is the removal of phosphoric acid from Central Kyzylkum phosphates by fluoride and sulphate additives during the extraction of phosphoric acid, iron and aluminium, calcium, magnesium, sulphate, fluorine during the ammonium phosphate acid extraction phase. Study the process of producing environmentally friendly and fully water-soluble ammonium phosphates.Methods. The study used chemical, physico-chemical (photocolorimetric, pH-metric, electron-microscopic) and statistical processingof experimental data.Results. The continuation of the phosphoric acid extraction process simplifies the process by removing fluorine and sulphate additives, by deep cleaning of iron and aluminium, calcium, magnesium, fluorine and other additives in the produced acid, the main nutrient element in the finished product -P2O5has been achieved.
