Abstract

Phosphorus is present only as a trace element on the Earth, but is one of the important strategic resources for agricultural food production and for the chemical industry. Natural phosphate ore is traded worldwide, mainly as a raw material for fertilizer. Approximately 147 × 103 kt of phosphate ore was mined in the world during 2005. Of this, 24.7% (36.3 × 103 kt) was produced in the USA, 20.7% (30.4 × 103 kt) in China, and 17.1% (25.2 × 103 kt) in Morocco, while there are essentially no deposits of phosphate ore in Japan or the EU (USGS,2012). It is of concern that, due to growing world demand for fertilizers, deposits of high-grade phosphate ore could be exhausted within the next 100 years (Vaccari 2009), and the average price of the ore in 2008 was approximately doubled that in 2007. Concerning the restricted supplies of phosphorus resource, it is important to consider the quantity and availability of phosphorus resources that currently remain untapped.
