2018-6-28  Phosphorus is common within geological materials. The average continental crust contains 0.27% P2O5.1 Phosphorus is the primary resources to produce fertilizer and phosphorous-based products.2 Phosphorus is neither substitutable nor recyclable, therefore, the total demand must be provided through the mining, beneficiation and chemical processing of phosphate ores. The key to understanding the association between environmental pollution and phosphate rocks lies in appreciating the mining and processing effect of phosphate ores. Phosphorus is normally produced by mining and beneficiation of Phosphate ores.3 Mines produce large amounts of waste including toxic metals and radioactive elements.4 The mining and beneficiation process results in the majority of these hazardous elements being lost either to waste disposal or to the environment, mainly soil, water, atmosphere and human food chain.5,6 Apatite is the dominant mineral in phosphate ores.

How phosphate is mined and processed

2014-4-21  Sedimentary phosphate tends to be found in loose sediment, so it can be mined with dredge lines (or picks and shovels). In Florida, the phosphate is found mainly in one layer of clay and sand that’s about 10-20 feet thick, and 15-50 feet below the surface. After the heavy equipment digs out the overburden (the sediment above the desired layer), they remove and dump the phosphate-rich sediment into a pit. That sediment is mixed with pressurized water to make a slurry, and that slurry sent through miles of pipeline. Making and pressurizing the slurry requires a lot of electricity (15 kwh per ton of phosphoric acid) as well as water. Many phosphate mines
