The main objective of this paper is to address the environmental issues that arise during the extraction of phosphate ore at Abu-Tartour mining area, Western desert, Egypt. Although the mine locates in the heart of the desert, the mining operations for ore extraction either from the underground mine, or from the surface mining work, do have several …

Abu-Tartur phosphate mine is the largest phosphate mine in Egypt. The mine located adjacent to Abu Tartur plateau, some 50 Km to the west of El Kharga Oasis, Western Desert of Egypt (Figure 1). The estimated phosphate ore reserves in the area may reach up to billion tons. An extensive geological drilling exploration

The leaching of rare earth elements (REEs) from Egyptian Abu Tartur phosphate rock using phosphoric acid has been examined and was subsequently optimized to better understand if such an approach could be industrially feasible. Preliminary experiments were performed to properly define the design of experiments. Afterward, 2^4 full factorial …

Abu Tartur phosphorites are considered as highest-grade in Egypt (attain average of 25 wt.% P 2 O 5) and considered as one of the most important factors in development in Abu Tartur area.Preliminary exploration of the mining area (about 108 km 2) led to an estimation of 987 million tons as economic reserve with an average of P 2 O 5 content not less than …
