| titleOfInvention | PROCESS OF RECOVERY OF URANIUM FROM ORTHOSPHOSPHORIC SOLUTIONS |
| abstract | The invention relates to a process for recovering uranium from orthophosphoric uranium solutions resulting from the sodium tripolyphosphate manufacturing process (STPP). The process consists in precipitating the uranium from the neutralized phosphorus solution with sodium hydrosulfite; the solution is then sent to a decanter in which the uranium sludge is deposited. It is separated, filtered, washed and dissolved in nitric acid. From the nitrate, at pH = 2.5, a nuclear purity concentrate of uranium is precipitated with hydrogen peroxide. The final precipitation is done with strictly maintaining the pH, adding a dilute ammonia solution. |
