introduction : Phosphate rocks are vital non-renewable resources and are essential components in agricultural fertilizers and phosphorous-based chemicals [1-4]. About 95% of the phosphate produced around the world is consumed in fertilizer industry [5, 6]. Phosphate deposits can be divided into three groups (і) sea sediments, (іі) igneous and (ііі) biogenetic deposits [7].
Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore …
The contents of natural radionuclides (226Ra, 232Th and 40K) were measured in sedimentary phosphate rock samples (Abu-Tartur phosphate, Western Desert Egypt) by using gamma spectrometry (NaI (Tl ...

where the economic phosphate bed lies at its base (Baioumy and Tada 2005). Most of the phosphate beds appear as mas-sive rock with thicknesses that range between 2 and 7 m. Large deposits of phosphorite are found in the phosphate zone in Quseir-Safaga Region at Eastern Desert (El-Anwar et al. 2019) and Abu Tartur Plateau at Western Desert
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 core model. The …
In a typical test, the weight of the oxide concentrate obtained represented 4% of the weight of the phosphate rock treated, which agrees with the work of Habashi et al. [3] on Florida phosphate rock. Analysis of the concentrate produced from Abu Tartur phosphate rock was found to give 96% CaO, 2.8% Ln 2 O 3, 0.6% P and 0.009% Fe. This indicates ...
Key Facts. Origin: Our Egyptian rock phosphate is mined from the Nile valley between Edfu and Qena (Sebaiya East and West) and the New valley at Abu Tartur along the Nile River.; Concentration: Our rock phosphate boasts varying concentrations of phosphorus, typically ranging between 20% and 32%.; Annual Production: With an impressive capacity of up to …
By varying nutrient supply, the RP dissolution reactions can be significantly enhanced, and the results indicate that the efficiency to dissolve RP was significantly higher with glucose, followed by arabinose; other sources were ineffective. Inorganic Phosphate (Pi) is an essential nutrient for plant growth and development, however that most soils have in low …
Phosphorus is the most required nutrient of plants, but its availability in Egypt is relatively low. The use of phosphate solubilizing microorganism to dissolve phosphate content of phosphate ore instead of conventionally methods is an ecologically safe and economically reasonable. In this study dissolution of phosphorus from Abu Tarture Egyptian ore which has low solubility level …
Jan 24, 2019 Phosphate rock (PR) is considered the cheapest P fertilizer Phosphate rock sources may be of igneous or sedimentary origin In Egypt, the natural phosphate rock is located in Sebaiya (Nile Valley), Safaga (Red Sea), and Abu Tartur (Western Desert) The higher the organic matter contents in soil, the better dissolution of the PRIt was ...
Variable loads of heavy metals (e.g. Cr, V, As, Cd, and U) are detected in the Abu-Tartur phosphorite at average contents lower than its counterparts at the Nile Valley and Red Sea provinces as well as other parts of the North African phosphorites belt (e.g. Tunisia and Morocco) (Table 1).This is not considered to be a guarantee or evidence for the little …

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 ...
As high grade deposits of phosphate rock are being depleted day by day in the world, future sources will be derived from low grade rocks containing various impurities. Low grade phosphate rocks are not suitable for direct use in acidulation plants unless their tricalcium phosphate (TCP) content is increased to 70% or more, using conventional methods such as crushing, …
Although this is the first time that REEs are leached from Abu Tartur phosphate rock with phosphoric acid, the idea of directly leaching REEs from a raw material as a preprocessing step is not new ...
Dilute acetic acid solution has the capability to react with the carbonates, but not with the tricalcium phosphate (TCP) itself.In this work, the effect of acetic acid concentration, liquid/solid ...
