Phosphate Rock is an excellent natural source of phosphorus calcium and many essential trace elements. It contains over 30 percent total phosphate (38 percent available) and 48 percent calcium (as CaO). Phosphate rock has approximately one fifth the neutralizing power of lime. Natural rock phosphates are from deposits of apatite rock formed
Phosphate is the second most widelyused fertiliser nutrient after nitrogen. Phosphates for the use in fertilisers are the most important factor in driving demand for phosphate rock. Almost over 90 percent of annual phosphate rock production is used in chemical fertiliser products with the rest being
demand for phosphate rock. Almost 90 of annual phosphate rock production finds its way into chemical fertiliser products. Industrial enduse sectors consume around 6 of phosphate rock produced with additives making up about 4 . Phosphate rocks are a primary source of phosphorous.
· Saudi Arabia only sells downstream products (MAP DAP) Russia is the only producer of highpurity (39 ) rock Downstream Intergrated 85 Middle East and Northern Africa 70 Other Traded 30 15 70 of traded phosphate rock is sourced from the Middle East and Northern Africa
· Phosphate of Lime equivalent to x percent P2O5). Sales of phosphate rock are generally by annual contract with consumers with minimum grades about 30 P2O5 (about 66 TPL). This means that a 6 P2O5 phosphate rock will need to be upgraded by a factor of 5 times to make a saleable product.
· The revolution in bulk shipping (see Lundgren 1996) and continuing improvements in domestic transport efficiency in producing nations have helped to reduce real transport costs for phosphate rock and its downstream products. Yet during the recent mining boom the high price of oil and a shortage of ships to transport phosphate products had a

The 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.
Today in the phosphate market about 85 of the world s phosphate rock production is owned by the guys who make the downstream products be it fertilizer or the purified phosphoric acid that makes

· Phosphate Rock Processing Process Description15 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation drying or calcining at some operations and grinding. The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475. The
· It is specialized in phosphate rock mining yellow phosphorus production the downstream production of phosphoric acid red phosphorus and a variety of phosphate. Our Company is located in Sichuan province where has a rich abundance of phosphate rock resource mainly distributed in Qingping and Jinkouhe phosphate rock regions.
· flawed assumption that the world reserve of phosphate rock is a static figure. Market dynamics could make it possible that phosphate reserves increase over time. Growing demand and limited supply caused phosphate rock prices to soar in 2008. After years of low and relatively stable prices phosphate rock prices are

Global Phosphate Market. The global phosphate rock concentrate market was roughly 206 million tonnes in 2012. Most of the phosphate rock produced was by companies who own deposits and use the concentrate to manufacture downstream fertilizer products. The merchant phosphate rock market was approximately 30 million tonnes in 2012. Based on
· Keywords Phosphate rock Semihydrate phosphogypsum Insoluble impurities Waterinsoluble phosphates In this work a chemical and mineral composition of phosphate rock and phosphogypsum was investigated in order to identify which impurities of phosphate rock prevent natural phosphates from decomposing in full during the production of phosphoric
· Today in the phosphate market about 85 of the world s phosphate rock production is owned by the guys who make the downstream products be it fertilizer or the purified phosphoric acid that makes its way into food. What is interesting as you look at phosphate is the guys who have that additional rock are actually not necessarily looking to
· OCP moved into downstream processing in 1965 converting lowergrade rock to phosphoric acid and fertilisers at its plants at the coastal town of Safi. In 1975 Maroc Phosphore was established as a 100 subsidiary of Groupe OCP primarily to add value to more rock and to export intermediate phosphate products.
