The vegetation-environm ent relationships in Abu Tartur are descri bed. Data sets (42 species in 38 plots) beside the pip-line enriched from 13 wells were analyzed, usin g multivariate procedures ...
Abu Tartur phosphorites are characterized by high concentrations of ~ REE[ (303- 925) x 10-6] compared with other regions. These higher ~REE may be attributed to the higher abun- dance of pelletal apatite in Abu Tartur phosphorites (Germann et al., 1984) and/or to the higher abundance of iron sulfide mineral (pyrite) which scavenges REE from ...
According to the minister, the complex will be built within the Abu Tartur mine, on an area of 560,000 sqm and a storage area of 3m sqm. El Wady for Phosphate Industries and Fertilizers Company ...
Phosphorites in Egypt occur in the Eastern Desert, the Nile Valley and the Western Desert at Abu Tartur area and present in Duwi Formation as a part of the Middle Eastern to North African phosphogenic province of Late Cretaceous to Paleogene age (Campanian-Maastrichtian). The Maghrabi-Liffiya phosphorite sector is considered as the most …
The aim of the present study mainly focuses on the role of two geochemical analyses techniques of XRF for measuring major oxides and trace elements and ICP …
The kerogen in the Abu Tartur section is of type III with the exception of sedimentary deposits at the Duwi/Dakhla transition. Low T max, odd-over-even …
The phosphate-glauconite rich deposit of the Campanian Duwi Formation at the Abu Tartur Plateau in the Western Desert of Egypt represents one of the largest …

The phosphorites of Abu Tartur in the Western Desert were sampled from both surface exposures and the subsurface experimental mine. Phosphorites of the unexploited main beds of Shekh Abdallah and Edmonstone in Dakhla oasis, Ghanima in Kharga oasis, Gebel Hefhuf in Bahariya oasis, Abu Had near Qift at East Qena, and G. Sofraiyat SW Sinai were

Three main sites are promising for the phosphate mining, these are: 1) The Abu Tartour mine (with estimated reserves of 1 billion tons and up to 31% P 2 O 5); 2) The Sibaiya mine (with a reserve ...
Background Phosphorus is one of the essential nutrients required for plant growth. Although it is moderately available in nature, it is a deficient nutrient in most soils especially calcareous soils. Phosphate rock (PR) is considered the cheapest P fertilizer. Phosphate rock sources may be of igneous or sedimentary origin. Results In Egypt, the …
Abstract. The phosphorite deposit of Abu-Tartur plateau, Western Desert, Egypt is one of the largest phosphorite deposits of the world. Previous investigations had …
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 agronomic potential of the Abu-Tartur phosphate wastes was investigated through four mixtures of phosphorite, glauconite, and shale namely, M#1 (1 …
Dissolution of uranium and rare earth elements from the Abu-Tartur phosphate rocks, Egypt using a mixed EDTA + nitric acid solution was studied. The eff ect of factors such as particle size, EDTA ...
the Nile Valley, along the Red Sea Coast, on the Abu Tartur Plateau and in the Sinai (Said 1990). The Abu Tartur phos-phorite contains from 35 to 71% of phosphate minerals (most commonlyoftheapatitegroup)(El-Anwaretal.2019;Wassef 1977; Zidan 1998). The Egyptian phosphorites have been the subject of several studies due to their economic importance
The Abu Tartur mine is located in the Western Desert of Egypt, 50 km west of El Kharga City. Geologically, the Abu Tartur plateau is built by a sequence of Upper Cretaceous (Campanian - Maastrichtian) phosphorites, black shales and glauconitic sandstones. The phosphate deposits are of great economic importance and have been mined since their …
The low content of uranium in Abu Tartur phosphate rock (averaging 25 mg/kg) is significant as compared to domestic phosphate deposits and is probably due to post-depositional leaching [2] . 2 Experimental 2.1 Analysis For analytical control during processing of the working sample, a simple and rapid method for the determination of the …
In this paper, the surface subsidence data were collected over working longwall panel at Abu-Tartur phosphate mines after the face had been advanced 280m. Different mathematical theories namely Bals', Peng's, Knothe's and Peck's theories are applied to predict the subsidence trough over the excavated panel. The obtained results are …
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, 24 …
Abstract Leaching of uranium and REEs with oxalic acid from the Egyptian Abu-Tartur phosphate rock (PR) was studied. The effect exerted on the leaching process by oxalic acid concentration, agitation time, solid to liquid ratio, and leaching temperature was determined. The leaching kinetics of uranium and REEs were evaluated by the shrinking …
