leaching. Phosphate leached from guano phosphatizes the underlying rocks in some areas, forming apatite where the host rock is limestone and forming aluminum- or aluminum-iron-phosphate minerals where the underlying rock is a silicate. Individual deposits of both igneous apatite and marine phos
Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than ...
Rock phosphate is the raw material used in the manufacture of most commercial phosphate fertilizers. Ground rock phosphate was ounce applied directly to acid soils. Phosphate rock processing consists in the separation of phosphate from the mix of sand, clay and phosphate that makes up the matrix layer.

IRAQ. In 2001, Iraq produced hydraulic cement, nitrogen, phosphate rock (from the Akashat open-pit mine), salt, and native Frasch sulfur (from underground deposits at Mishraq, on the Tigris River, south of Mosul), as well as clay, gypsum, lime, limestone, industrial sand (glass or silica), sand, gravel, and stone.
producers of phosphate rock and phosphate fertilisers are in the USA, the former USSR, China, Africa and the Middle East. The phosphate industry is also an important contributor to national economies in many developing countries. The mineralogical composition of phosphate ore, as described by various researchers (Carbonell-
Phosphate rock deposits can be sedimentary or igneous, but more than 80 percent of the world's current production of phosphate rock is mined from sedimentary deposits formed by deposition of phosphate-rich materials in marine environments. Large sedimentary deposits are located in China, the Middle East, northern Africa and the United States.

Sep 20, 2012· After mining, phosphate rock is beneficiated using washing, screening, floatation, cycloning, calcining or some other processes to give a product with 27-37% P 2 O 5 (12-16% P). To produce P fertilizers, the rock is reacted with acids, which is the process that Lawes and Gilbert patented in the mid-1800s.
While this presents a major challenge to phosphate rock exporters, phosphate fertilizer producers - particularly those that do not have an integrated source of phosphate rock - stand to benefit. The key to this continued market divergence lies within China and the behaviour of exporters there.

Most inorganic phosphates used for this purpose are derived from natural rock phosphates, principally found in Africa, northern Europe, Asia, the Middle East and the USA. However, in their natural form these are unsuitable for direct use in animal feed because the phosphorus they contain cannot be metabolised by animals.
