Phosphate rock production and consumption. U.S. production of phosphate rock in 2012 was 30.1 million metric tons, valued at $3.08 billion. Total world production of phosphate rock in 2012 was 233 million metric tons. China was the leading producer, with 41 percent of world production, followed by the United States, Morocco and Western Sahara.
Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the world's leading producer and consumer of phosphate rock, which is

Robust strategies in times of uncertainty The future of the global phosphate rock market is beset with uncertainty. The
Phosphorus is mined primarily as phosphate rock, a fairly common rock found worldwide. It takes about 1 ton of phosphate to produce 130 tons of grain, although this figure is highly variable depending on soil conditions, farm history, crop type, and fertilizing efficiency (Vaccari, 2009).
As of 2006, the US is the world's leading producer and exporter of phosphate fertilizers, accounting for about 37% of world P 2 O 5 exports. As of 2008, the world's total economic demonstrated resource of rock phosphate is 18 gigatonnes, which occurs principally as sedimentary marine phosphorites.
Nov 29, 2016· If you include this disputed region, Morocco holds more than 72 percent of all phosphate-rock reserves in the world, according to the most recent United States Geological Survey study. …

Phosphate Rock. 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.
Rock phosphate is accepted in the NOP because it is not synthetic and has not been treated by acids as in super phosphate and other more available forms. Gardeners would not use rock phosphate because at the scale at which most people garden, they can get …
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 ...
