The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

— There are 27 phosphate mines in Florida, covering nearly half a billion acres. Phosphate pebbles were found in the Peace River in the 1880's, setting off a mining rush where Hardee, Hillsborough, Manatee, and Polk counties meet. "Bone Valley" was named for the large number of prehistoric fossils found there.
Modern phosphate mining involves complete removal of the land—plants, animals, soil, water, even bedrock—and then its approximate reconstruction minus the phosphate. The steps are as follows: The area to be mined is first stripped of vegetation and the water table is lowered, typically by digging a deep trench around the area.

— The mining process in Morocco involves both open pit and underground mining methods, depending on the depth and accessibility of the phosphate deposits. After extraction, the phosphate rock undergoes beneficiation processes including crushing, screening and washing to remove impurities and increase its phosphate content.
— Before the mining process can begin, owners must conduct wildlife surveys, ... However, the HPS Enterprises II mine proposed a different method to mine the phosphate.
Phosphate is an important mineral because it contains phosphorus (P), a key nutrient for plant growth, in addition to human and animal health. This 6-minute video by Nutrients for Life shows the process of mining phosphate rock and …
Florida's phosphate mining today accounts for about 80% of the phosphate used in the United States, as well as about 25% of the phosphate used around the world. ...

As mining is completed, the reclamation process begins. Phosphate mining disturbs about 5,000-6,000 acres of land annually; approximately 25-30% of these lands are isolated wetlands or wetlands connected to waters of the state, according to the Florida Bureau of Mine Reclamation. Besides planning, there are two additional stages of land ...
Digging the phosphate out of the ground is only one step of the mining process. Phosphate comes out of the ground as part of a matrix, which is a mix of the phosphate, sand and clay. The phosphate must be separated from the sand and clay it has melded with in the ground over millions of years.
phosphate mining operations; however, their characteristics present many reclamation challenges. CSAs comprise 40% of the post-mining landscape, have dam walls between 20 and 60 feet in height, and remain irreclaimable for many years during active use. When no additional clays are to be added, CSAs must undergo a protracted process of draining
— US phosphate mining capacity is projected to remain relatively steady between 2018 and 2022, and projected growth of the worldwide phosphate mining market is expected to be 14%. In 2020, phosphate-mining production is expected to grow by 2% through 2020. ... These types of wet-process phosphate products are used for things …
— Phosphate rock is used to produce yellow phosphorous, also known as P4, through a furnace process and, further downstream, phosphorous chemicals used in agriculture, mining, and aviation, in ...
— Conservation, public health and environmental justice organizations notified the Environmental Protection Agency today of their intent to sue the agency for failing to respond to a rulemaking petition requesting stronger oversight and regulation of toxic and radioactive waste from phosphate mining and fertilizer production. The notice comes …
— Furthermore, Bayer hires additional engineers and geologists to ensure the phosphate ore (and the phosphorus derived from it) is obtained in the most ecologically responsible manner possible. In terms of sustainability, the Caldwell Canyon mine has the potential to be the most advanced and innovative mine in the nation.
1. Optimize Use Improve phosphorus use efficiency in agriculture across new, recycled, and existing (legacy) phosphorus: Improving phosphorus use efficiency will reduce costs and demand for phosphate mining, increasing farmer income and decreasing phosphorus water pollution.To achieve this, microbial- and plant-based solutions must be enhanced, …
Marine Phosphate Mining is the newly proposed and fully unexplored process of extracting phosphate from the seabed. As of 2023, only landbased phosphate mining is taking place, but several companies have applied for licenses to exploit marine phosphate reserves, including in Namibia.
Phosphate producers face continual pressure to offer high quality products at the lowest price. Nalco Water delivers essential expertise with technically, economically and environmentally sustainable solutions that are tailored to the unique needs of your phosphate mining process.
— MEXICO CITY — A mining company trying to launch a controversial phosphate project in Mexican waters has won a lawsuit against the country claiming officials wrongfully rejected its environmental ...

— The most common steps during phosphate mining are the removal of the topsoil and overburden and the extraction of phosphate layers through open pit mining activities. Several methods are used to process phosphate ores . Open-pit mining methods are generally known to generate more waste rock than underground mining. The …
— The overview of the mining process is useful, if cheery. The draglines—the largest earth-moving equipment in the world, according to Mosaic, with buckets the size of a small bedroom—remove the "overburden," the top layer of soil, to reach the phosphate matrix that sits 30 or so feet below. ... through various steps, phosphate rock is ...
