Аннотация:The object of the study was a dump phosphogypsum produced by JSC Voskresenskiye Mineral Fertilizers, which was processed in order to isolate rare earth elements. The expediency of using a 10% solution of sulfuric acid for leaching is shown. The optimal leaching time was 1 hour of continuous mixing of phosphogypsum pulp. It was found that the largest amounts of REE: Ce, Gd, La, Nd, Pr and Y from the mother liquor are deposited in the pH range from 3 to 7.
