Abstract

In fact, bastnaesite, monazite and xenotime are the most important rare earth-bearing minerals known as sources for extraction of rare earths by hydrometallurgical approaches to produce intermediate products in the form of rare earth-chlorides, fluorides, halides, and oxides. In the following paragraphs I will summarize some of the rare earth elements extraction using variety of their extraction techniques from some treated Egyptian ores. Leachability of lanthanides from the radioactive pegmatite pockets found in Gabal Abu Furad area, southwest Safaga city, limited by latitudes 26°37′ and 26°43′ and longitudes 33°36′ and 33°43′E. Central Eastern Desert, Egypt. It was investigated using different acids at different concentrations, liquid-to-solid ratios, contact times and temperatures in order to determine the optimum recovery conditions. The best leaching efficiency was obtained with 40g/l HCl solution; 8hrs contact time, 90°C temperature and 1:5 (g/ml) solid: liquid ratio. Afterwards, lanthanide stock solutions were prepared by applying the optimum leaching conditions.
