Method for the recovery of uranium from pregnant liquor solutions |
| 摘要 |
A method for the recovery of uranium from pregnant liquor solutions that comprise levels of chloride of 5 to 80 g/L by using an amino phosphonic functionalized resin. The method includes providing an amino phosphonic functionalized resin; providing a pregnant liquor solution comprising and uranium; passining the pregnant liquor solution over the amino phosphonic functionalized resin to separate the uranium from the pregnant liquor solution; and eluting the uranium. |

1. A method for the recovery of uranium from a pregnant liquor solution comprising:
i) providing an amino phosphonic functionalized resin in acid form; ii) providing a pregnant liquor solution comprising chloride and uranium; iii) passing the pregnant liquor solution over the amino phosphonic functionalized resin to separate the uranium from the pregnant liquor solution; and iv) eluting the uranium wherein the chloride is present in an amount from 5 to 80 g/L, and wherine the pregnant liquor solution has a pH of from 0 to 4. |
