· Kazakhstan has 160,000 tons of coal resources at 155 sites, including 10 deposits of coal, bitumen and lignite. The iron ore resources in Kazakhstan are among the world''s cleanest, free of impurities. Thanks to Zhanatas and Karatau deposits, Kazakhstan is the world''s second largest in reserves of phosphorite (after Russia).

contact usSource: USGS 2020 1. 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.This is insoluble, so cannot directly be used as a ...
contact us· Morocco remains the largest exporter of phosphate. However, the high cost of mining and threats of war has derailed the production of phosphate in the country. Chin is a distant second with 5% of the total reserves, translating to approximately 3.1 billion tons. However, China remains the largest producer of phosphate at 138 million metric tons.
contact usMarine phosphorites are known to concentrate rare earth elements and yttrium (REY) during early diagenetic formation. Much of the REY data available are decades old and incomplete, and there has not been a systematic study of REY distributions in marine phosphorite deposits that formed over a range of oceanic environments. Consequently, we initiated this study to determine if marine ...

contact us· Introduction Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate bearing minerals. The phosphate content of phosphorite is at least 15 to 20%; if it is assumed that the phosphate minerals in phosphorite are hydroxyapatite and fluoroapatite, phosphate minerals contain roughly ...

contact usThe term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

contact us· Morocco has considerably greater reserves than any other country, or indeed all other countries added together, and consequently has the largest R/P ratio at nearly 2000 years. To match the global R/P ratio of around 370 years, Morocco''s production would have to instantly increase from 26 Mt to 135 Mt per year, which is more than a 5-fold increase.
