Abstract |
|
|
| The chemical processing of Allouga locality ore material at Um Bogma Formation, occurring at southwestern (SW) Sinai, Egypt, was studied for the recovery of uranium and other associated elements. After the completed determination of optimum leaching conditions of uranium, the spent ore material left behind was subjected to another leaching process of REEs and Cu. Concerning uranium leaching using sodium carbonate as a leaching agent, it was thus possible to achieve leaching efficiency exceeding 95%. This was followed by the second procedure for REEs and copper leaching from the spent left behind using citric acid. The obtained leaching efficiency was about 90% of REEs and 95 % of copper content. The leached metal values namely; U, REEs, and Cu from the study ore material were then recovered as marketable products. These conditions were applied to technological sample assays of 6% CuO; 3500, ppm U, and 2000 ppm REEs. |
