The amount of remaining.phosphate rock reserves and resources worldwide has become an issue of speculation.It has been hypothesized that phosphorus (phosphate rock) production will "peak" in 20033-2034 and then production will unavoidably decrease as the reserves are depleted Because phosphonas is one of the three elements critical to plant growth, dire consequences …

Across the world, there is an increase in phosphate mining capacity and an increase in global sources that are taking over the market. Phosphate rock mining in China is greater than in all other countries. *Morocco includes the Western Sahara province as well. Mining in the large Moroccan reserves continues to increase.

It is mainly used in fertilizer industry. In addition to apatite, phosphate rock contains impurities. Raw phosphate ores are beneficiated to meet the industry requirements. There are many losses in the process of using phosphorous which requires various remedial measures to match the world's increasing consumption intensity of phosphorous.
