Abstract |
|
|
| Egypt needs to provide large quantities of nuclear fuel, after its decision to build a number of nuclear plants that will run on nuclear fuel. Uranium is the most important nuclear fuel and has been utilized for producing electrical energy without the threat of global warming. South Eastern Part of Wadi Baroud is located in the Northern Eastern Desert of Egypt at about 20 km westward Safaga City. The purpose of this study was to investigate the mineralogical content of South Eastern part of Wadi Baroud microgranite which revealed that the main mineral associations were represented by uranium, thorium and rare earth elements (REEs)-minerals. Also to investigate the process of sulphuric acid leaching of a representative samples from a new ore of uranium occurrence in South Eastern Part of Wadi Baroud. From the acidic atmospheric agitation leaching study upon the dissolution of U, Th and REEs from the study ore material, it can be concluded that this leaching method is satisfactory in dissolving 97.6 %, 98.8 % and 54.9 % of Th, U and REEs respectively, contents by using the following optimum leaching conditions; Ore grain size -200 mesh; H2SO4 Concentration 20 %; agitation time 4h; Leaching temperature 75 ºC; Solid/liquid ratio (S/L) 1/2. |
