Phosphate rock production and depletion Regional

 · 1. Introduction. Phosphorus (P) is an essential element for all life on earth and global food production is highly dependent on the use of fertilizers produced from phosphate rock ().As phosphate rock is a finite resource and global production is rising fast several studies have warned that a maximum phosphorus production could be reached within a foreseeable future (Déry and Anderson 2007

 · Abstract Phosphorus has a number of indispensable biochemical roles but it does not have a rapid global cycle akin to the circulations of C or N. Natural mobilization of the element a part of the grand geotectonic denudation-uplift cycle is slow and low solubility of phosphates and their rapid transformation to insoluble forms make the element commonly the growth-limiting nutrient

Minerals Free Full-Text Review on Beneficiation

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate the beneficiation of the low-grade phosphate ore is hence of great necessity.
