Phosphorus is an essential element in the buildup of the human body and all other livings skeletons. The main source of
phosphorus is the natural phosphate. About 95 percent of the produced phosphates are consumed in the agricultural sector as
fertilizers and animal feed stocks. Most of the balance is converted into phosphoric acid and elemental phosphorus which are
the raw materials for manufacturing various phosphate compounds. The world annual phosphate production in 2012 is around
217 million tons, and the global reserves amount to 67 billion tons.
