Florida's Phosphate MinesThere are 27 phosphate mines in Florida, covering more than 450,000 acres. Nine phosphate mines are currently active. Nine mines are 100 percent reclaimed and released from reclamation obligations. The remaining mines are either not started or are shut down. Phosphate mines typically range in size from approximately 5,000 to 100,000 …

WhatsApp: +86 18221755073Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43-), located in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Animals absorb phosphates by eating plants or plant-eating animals.
