A high-uranium phosphate rock from the Itataia deposit, located in the state of Ceará, Brazil, was milled in a pilot plant for wet-process phosphoric acid production. Further processing with solvent extraction (DEHPA/TOPO) was used aiming to recover uranium from the phosphoric acid. The distribution of natural radionuclides with long physical half-life of the

: China primarily contains medium and low-grade phosphorus ores that are used to produce phosphoric acid. Here, we provide an overview of phosphoric acid production processes, including wet, thermal, and kiln methods, as well as the fundamental principles, major equipment, and technological aspects of each process. Progress in the kiln method using lowgrade phosphate rock is described, which involves the KPA and CDK processes. The literature shows that the addition of admixtures adds great competitiveness to kiln phosphate production methods and has considerable development prospects.
