Phosphate content has been estimated with high accuracy based on the results of four machine-learning tech-niques. The most efficient technique for estimating phosphate content is optimizable (OGPR), which gives correlation coeffi-
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 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 …
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
Mineralogy of Abu Tartur phosphate Towards the end of the last century the first deposits of the Western Desert in Egypt, around the Dakhla and Kharga oases (Fig. 1), were discovered. Sedimentary succession is the same in all Egyptian deposits, confined to an East–West trending belt between 25 and 30° N. Phosphate-bearing sediments occur …
