Abstract |
|
|
| Abnormal leaching reagent, thiourea has been studied for leaching both of uranium (U) and copper (Cu) content from mud crack ore material, Talet Selem area, Sinai, Egypt. Several leaching parameters have been investigated e.g. Thiourea concentration, mixed solid / liquid ratio, leaching time and finally leaching temperature to optimize the leaching process. The prepared leaching solution rich in U species and Cu ions was adjusted to direct precipitation process using Na2S for separating Cu ions and directed to ion exchange process (batch technique) using Amberlite IRA400 (Cl- form) to recover U species. The recovered product (Na4U2O7.xH2O) and CuS where confirmed using SEM- EDAX unit. |
