What are phosphorus rocks?
- Phosphorus rocks or phosphate rocks are unprocessed ores.
- Phosphate rock deposits can be sedimentary (formed from sediment deposited by water or air) or igneous (having solidified from lava or magma).
- However, the easiest way to obtain phosphorus is by way of mining and concentrating phosphate rock from the phosphate deposits.
Used in fertilizers
- Worldwide, more than 85% of the phosphate rock mined is used to manufacture phosphate fertilizers.
- All common fertilizers have an “N-P-K” rating. Phosphorus is the “P” in fertilizers, which is essential for plants.
Where is it found?
- Phosphate rock deposits can be sedimentary or igneous and are mined from sedimentary deposits formed by the deposition of phosphate-rich materials in marine environments.
- Large sedimentary deposits are located in China, Middle East, Northern Africa, and the United States.
- Meanwhile, the igneous deposits are mined in Brazil, Canada, Finland, Russia, South Africa, and Zimbabwe.
