phosphate rock

Mineral Resource of the Month: Phosphate

Phosphate rock refers to unprocessed ore and beneficiated concentrates that contain some form of apatite, a group of calcium phosphate minerals. Apatite in phosphate rock is the primary source for phosphorus in phosphate fertilizers. More than 80 percent of the world’s current production of phosphate rock is mined from sedimentary deposits, which were formed by the deposition of phosphate-rich materials in marine regions. Most of the rest comes from igneous deposits of carbonatites and silica-deficient intrusions. The grade of phosphate rock is classified by the phosphorus pentoxide content.

Could U.S. phosphate deposits help meet growing rare earth demand?

The modern world runs on rare earth metals — they are essential ingredients in light bulbs, smartphones, wind turbines and military weapons, among other uses. Currently, China supplies more than 95 percent of the global demand for rare earth elements (REEs), giving it a virtual monopoly. But new research suggests that the United States may contain vast domestic reserves of its own that could dwarf known deposits.
