Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0-30-0, but the grade is noted as 0-3-0, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops. Many of the mines that produced rock phosphate are closed, and most of the marketed rock phosphate comes ...
Phosphorus (P) is one of the most important nutrients for phytoremediation of arsenic (As)-contaminated soils. In this study, we demonstrated that As-hyperaccumulator Pteris vittata was efficient in acquiring P from insoluble phosphate rock (PR). When supplemented with PR as the sole P source in hydroponic systems, P. vittata accumulated 49% and 28% higher P …

The results of XRD and FT-IR analysis of the raw and calcined phosphate rocks showed the dominant minerals in the raw phosphate rock are fluorapatite (Ca 5 (PO 4) 3 F), dolomite (CaMg(CO 3) 2) and quartz (SiO 2). Many reactions occurred during the calcination of phosphate rock, which was showed in Table 2. R1 occurred at 500 °C and finished at ...
The South Carolina phosphate mining industry began after the Civil War and dominated world production in the 1880s. Mining began in late 1867 on plantations near Charleston after the gentlemen-scientists Francis S. Holmes and St. Julien Ravenel and the chemists N. A. Pratt and C. U. Shepard discovered that local "stinking stones" contained …
Therefore, our world is heavily dependent on phosphate rock (PR) as the dominant source of P for the enhancement of plant productivity and to secure a stable food supply for an increasing global population. In 2010, world PR mine production was about 176 Tg. High-quality PR production is predicted to peak this century, regardless of the growing ...
Phosphate rock and phosphorite are names used for sedimentary rocks that contain at least 15% to 20% phosphate on the basis of weight. The phosphorous content in these rocks is mainly derived from the presence of …
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 full factorial design was …
Calcium bound phosphorus is the dominant form of inorganic phosphorus in the studied sedimentary phosphate rock. Aluminium bound phosphorus is the second, iron bound phosphorus is the third most ...

Phosphate rocks are a vital resource for world food supply and security. They are the primary raw material for phosphoric acid and fertilizers used in agriculture, and are …
Phosphate is an essential inorganic compound composed of a phosphorus atom bonded to four oxygen atoms. This molecular structure is a fundamental building block for many vital biological processes, including …
The dominant elements detected in phosphate rock samples by the X-ray fluorescence are CaO, P 2 O 5, SiO 2, Al 2 O 3, MgO, and Fe 2 O 3. 3.7 X-ray Diffraction (XRD) Analysis. The structural determination of the powder samples of phosphate rock has been analyzed with X-ray diffraction, and the structure has been analyzed by using powder X-ray ...
Moderately labile P pool (extracted by using 0.1 mol L −1 NaOH and 1 mol L −1 HCl) was the dominant fraction in all treatments (Fig. 3 b). ... RP-phosphate rock, TP-triple superphosphate, WP-no P fertilizer. 20 and 6 represent the time interval between the last fertilization and soil sampling. *Means followed by the same letter, uppercase ...
Naturally occurring mineral products having sufficient phosphate content to be of commercial value are classified as phosphate rock. The grade or phosphate content of these products has been traditionally reported as percent Ca 3 (PO 4) 2, which is referred to as bone phosphate of lime (BPL), tricalcium phosphate (TCP), or triphosphate of lime (TPL).). …
When rock contains phosphate components between 5 and 50% (by volume), then it is phosphatic, and the name of the main lithology is used as a suffix (phosphatic limestone, phosphatic claystone, etc.). In addition, the dominant textural form of the phosphate …

According to the Fourier Transform Infrared Spectroscopy spectrums, gypsum is the dominant phosphate phase after both the single- and two-step methods. However, calcite and fluorapatite, dominant in the un-treated rock, are still present after the single-step, highlighting the differences between the chemical and the biological methods.
