Radiological assessment of Abu-Tartur phosphate,

The Abu-Tartur phosphate deposit was found to have lower activity than many others exploited phosphate sedimentary deposits, with its average total annual dose being only 114.6 microSv y (-1). This value is about 11.46% of the 1.0 mSv y (-1) recommended by the International Commission on Radiological Protection (ICRP-60, 1990) as the maximum

Upgrading of Abu Tartur Calcareous Phosphate via

2016-9-9  Abu-Tartur PR contains about 49.20% apatite mineral equivalent to 21.8% P. 2. O. 5 . and more than 50% of undesirable components including about 26% carbonate minerals. In this study acetic acid was used to eliminate the carbonate content of Abu-Tartur PR which would save acid consumption besides increasing the tenor of P. 2. O. 5, U and Ln.

The potential production of rock-based fertilizer and soil

Rock-based fertilizer and soil conditioner can be obtained from the Abu-Tartur mining wastes. Abstract The current phosphate mine wastes at El-Liffiya-Maghrabi sector, Abu-Tartur plateau, are represented by low-grade phosphorites along with overburden of glauconite and shale deposits.

Geochemistry and microprobe investigations of Abu Tartur

2010-7-1  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 25 wt.%.
