In the complex, production depends on the use of Abu Tartur Phosphate ore, and maximizing its added value instead of exporting it as a raw material. The project also contributes to the comprehensive development of the New Valley Governorate, as the project will provide more than 3,000 direct and indirect job opportunities. ...
La roche phosphatée est une ressource minérale importante, principalement utilisée dans la production d'engrais, de pesticides et de matières premières industrielles. Son processus d'enrichissement est conçu pour augmenter la teneur (en phosphore) et la récupération de la roche phosphatée, permettant ainsi une utilisation efficace ...
The constructed variogram and kriging models, as well as GIS-analysis, provide a clear understanding of all the elements distributed in the Abu Tartur phosphate ore and are very useful at the planning and mining stages. Purpose. This paper aims to estimate phosphate ore grade in the Abu Tartur area, Western Desert, Egypt, using four Machine Learning …

The Abu Tartur ore deposit occurs in the southeasternportion of Abu Tartur Plateau (Wassef 1977). The plateau covers about 1200 km2 in area, is about 400 m above the surface of the surrounding wadis, and about 540 m above sea level. In the southeast and northeast, it is limited by steep scarps and the plateau surface is formed of limestone ...
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 …
A selective leaching procedure for uranium and the REEs is applied upon Abu-Tartur rock phosphate of the W.D. of Egypt using a mixed reagent of citric acid / calcium citrate in a manner to leave the phosphate values almost intact for later processing. The leaching conditions have thus been applied upon a representative sample of the weathered ...
