How phosphate is mined and processes Mining 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 thats about 10-20 feet thick, and 15-50 feet below the surface.
The mining of pebble phosphate began in 1888 in central Florida and in the 1960s in Hamilton County. Today phosphate mining occurs primarily in the central Florida area (Polk, Hillsborough, Manatee and Hardee counties). The central Florida phosphate mining region covers approximately 1.3 million acres of land known as the Bone Valley.
4. Describe the phosphate cycle, and how the use of chemical phosphate fertilizer alters this cycle. 5. Identify how air, water, and land can potentially be polluted by phosphate mining, fertilizer production and fertilizer use. 6. Summarize the
The current mining operation probably takes advantage of phosphate-rich rocks residing in this riverbed. According to the Jordanian Natural Resources Authority, phosphate formations cover roughly 60 percent of the countrys total area, and reside mostly in a 300-kilometer- (185-mile-) wide swath that passes north to south through the country.
The very first unit operation in the beneficiation process is to disaggregate the various particles this actually starts while the matrix is flowing through the multi-mile pipeline from the mine to the beneficiation plant (see the phosphate mining primer). While in the pipeline, the matrix is exposed to shear forces as it passes thru the ...
Service, approved an expansion to the largest phosphate rock mine in Idaho. The expansion will allow the operating company to continue mining at the site for about 10 years, after which it will shift mining to a new mine that is under development in the same area.

Bone Valley stretches from Polk and Hillsborough counties south through Hardee, DeSoto, Manatee, and Sarasota counties. Polk County has been the mainstay of the Bone Valley mining operation, but that era is ending. Phosphate companies are now seeking permits to open new mining sites in Manatee, Desoto and Hardee counties.
Mining Techniques. The phosphate deposits occur anywhere between 30 and 50 feet below the ground surface. Due to the relative shallow depths of the deposits and the structure of the layer above it (i.e., mostly unconsolidated sand and clay), the phosphate matrix consisting of phosphate rock, sand and clay, is extracted through a process known as strip mining.
Few images of phosphate mining operations in Beaufort County are known to exist. The 35 images that Conrad Donner took of the Pacific Guano Company, a phosphate mining company operating on Chisolm Island, are especially important as they show key aspects of an industry crucial to the post-Civil War economy of Beaufort.
Phosphate Mining Linked To Sinkholes. Sinkholes form in central Floridas landscape due to groundwater reserves such as aquifers insidiously being destroyed by watershed destruction via phosphate strip mining operations. This is because the water contained in the aquifers hydraulically sustain the weight of the surface above.
