Abstract
Phosphoric acid for use in fertiliser applications is mainly produced by a ‘wet-process’, i.e. by digestion of phosphate ore with sulphuric acid. In such wet-processes, however, impurities like Cd and Ra, originating from the phosphate ore are distributed between the phosphoric acid and the byproduct, a calcium sulphate modification.
