| titleOfInvention | Oxidation of phosphoric acid plus K compound addition |
| abstract | This invention is directed to an improvement in the Hill phosphoric acid process, whereby the Hill process can be used with high-iron phosphate rock. The improvement involves oxidation of divalent iron in an early stage of the Hill process, followed by addition of a soluble potassium compound to the acid in the crystallizer. |
