Phosphorite - Wikipedia

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5. This occurs through washing ...

Phosphate mining in the United States - Wikipedia

In 2015, 27.6 million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and Morocco.The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion.. As of 2015, there are 10 active phosphate mines in four states: Florida, North Carolina, Idaho, and Utah.
