Phosphate deposits can contain significant amounts of naturally occurring heavy metals. Mining operations processing phosphate rock can leave tailings piles containing elevated levels of cadmium, lead, nickel, copper, chromium, and uranium. Unless carefully managed, these waste products can leach heavy metals into groundwater or nearby estuaries.

The majority of the phosphate rock mined in the US is used for manufacturing phosphoric acid and superphosphoric acid. These types of wet-process phosphate products are used for things such as ...

Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the world's leading producer and consumer of phosphate rock, which is

Ian Hore-Lacy, in Uranium for Nuclear Power, 2016. 9.3 Processing phosphates. Phosphate rock (phosphorite) is a marine sedimentary rock that contains 18–40% P 2 O 5, as well as some uranium with all its decay products, often 70–200 ppm U, and sometimes up to 800 ppm.The main mineral in the phosphate rock is apatite, and most commonly, fluorapatite—Ca 5 (PO 4) 3 F or Ca 10 (PO 4) 6 .
