The lithostratigraphic succession in the Abu Tartur area (Fig. 1, Fig. 2, Fig. 3) on the southeastern scarp of the Abu Tartur Plateau was described by Issawi et al. (1999). The Upper Campanian-Lower Maastrichtian phosphate-rich Duwi Formation unconformably overlies the Lower-Middle Campanian Quseir Formation ( Fig. 3 ), which consists of ...

First of all, Abu-Tartur plateau is characterized by Lat Jurassic-Tertiary rock units (Fig. 1a). The base of plateau es-carpment is occupied by Late Jurassic-Middle Turonian Nubia Group: Six Hills, Abu-Ballas, Sabaya, Maghrabi, and Taref formations. This group is considered to be the oldest rock units occurring in the study area as plains and ...

2. SUBSIDENCE MONITORING AT ABU-TARTUR AREA The phosphate deposit at Abu-Tartur area, located at 150m below the ground surface is exploited by longwall mining method. Three panels, 1200m long and 150m wide, have been developed and only one panel is being mined now by retreat mining method. The layout of the working panel is …

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 …

This is done using ''14" samples from the shales of the Dakhla and Duwi formations in Abu Tartur area. The samples have been analyzed using the geochemical method of Rock–Eval pyrolysis. The analysis shows that the total organic carbon content lies between 0.56 and 1.96 wt%. It also shows that kerogen is a mixture of type II and III ...

The oldest sedimentary rock in Abu Tartur plateau is the cross-bedded non-fossiliferous sandstone of the Nubia formation (Cenomanian to pre-Campanian). It is conformably overlain by the variegated shales of the Quseir formation which is overlain by the Duwi (phosphorite) formation of late Campanian to early Maastrichtian in age [18]. …

The separation of dolomite from Abu-Tartur phosphate ore using a similar amphoteric collector was conducted by Elmahdy et al. . Under the determined optimal flotation parameters, a concentrate of 0.53% MgO and 31% P 2 0 5 with a recovery of 90% was obtained. Measurements of the zeta potential and adsorption in the absence and …
