Geological and geochemical evaluation of phosphorite deposits in
The Kingdom of Saudi Arabia is considered as "a sleeping giant" in the Middle East and adjacent countries in terms of phosphate mining potential, with phosphate resources estimated to be>3,000 million tons (Mt) averaging 18 to 21 wt% P 2 O 5.Saudi Arabia has a vast distribution of phosphate rocks in the northern, southern, central, and …

Tethyan Phosphates and Bioproductites | SpringerLink
Abstract. Among the periods known to have been more especially phosphogenic, the Late Cretaceous—Paleocene is one of the best known, because of the number and size of mined deposits such as those of Morocco and the Middle East. All deposits of that period are linked to Tethys and the bordering platforms, the evolution of which was responsible ...

The presence of higher calcite content about 57.5% is a problem not only in Saudi phosphate ores but also for calcareous phosphate ores all over the world (Elgillani and Abouzeid, 2009, El-Shall, 1994, El-Shall et al., 1996). The chemical analysis of the rock revealed that P 2 O 5 = 25.1%, CaO = 52.7%, SiO 2 = 1.17% and CaO:P 2 O 5 ratio = 2.1 ...

Uranium from Phosphates
Phosphate rock (phosphorite) is a marine sedimentary rock which contains 18-40% P 2 O 5, as well as some uranium and all its decay products, often 70 to 200 ppmU, and sometimes up to 800 ppm. The main mineral in the phosphate rock is apatite, and most commonly, fluorapatite – Ca 5 (PO 4) 3 F or Ca 10 (PO 4) 6 (F,OH) 2.
