Ahead of the publication of the 2017 Phosphate Rock Cost Report, CRU undertook a research visit to Egypt's largest mine, Abu Tartour, as the mine's operator, Misr Phosphate Co., plans to construct its first phosphoric acid plant at the site. Egyptian phosphate rock is low cost but also low value Downstream facilities in Egypt remain …
The main component of rock phosphate is calcium phosphate (tricalcium phosphate, dicalcium phosphate) which is insoluble in water and thus unavailable to plants. During rock phosphate processing, phosphorus is extracted by dissolving the rock phosphate in low-pH solutions (sulfuric acid, nitric acid, or hydrochloric acid).
In similar terms, the phosphate deposits of East Luxor, Egypt, have signs of the migration of uranium-rich solutions, and this migration was directed from the depositional basin upward. However, post-consolidation enrichment of uranium was insignificant, as no concentration of uranium is recorded now along fractures or weak …

The recovery of fluorine and iodine in the production and concentration of wet-process phosphoric acid (WPA) can not only reduce environmental pollution, but also increase the added value of production. In this work, the phosphate rock was digested with H 2 SO 4, and the remaining H 2 SO 4 in the WPA was removed with Ca (H 2 PO 4) 2, then the …
Cadmium (Cd) has accumulated in New Zealand agricultural systems, predominantly from the application of phosphorus (P) fertiliser to soils. Elevated Cd concentrations in soils are an important ...

The activity concentration levels of 238 U, 226 Ra, 232 Th, and 4 K in soil samples collected around the rock phosphate storage facility in Richards Bay were enhanced relative to what was found in samples from the control area.
The results showed that heavy metalcontent was lower in Abu-Tartur phosphate than that in imported rock and were below the safe limits with theexception of lead whose concentration was found to be ...
rock phosphate is a clay material that is surface mined from the old settling basins of former hard phosphate rock mines in Egypt. Our rock phosphate contains about 20 32 % of P205 as well as a percentage of …
