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.

Phosphate rock as a low-cost bulk commodity (1945–2000) The commodity chain of phosphate fertilizer starts with the extraction of phosphate rock, typically in large open-pit mines. The raw material is transported from the mine into industrial plants where phosphoric acid Footnote 5 is produced in a chemical process by adding sulfuric acid.

Phosphate mining in Florida is open pit mining (see Fig. 1) where an overburden of approximately 10 m is stripped off and set aside and the clay/sand calcium phosphate matrix is removed. 1 During beneficiation, the calcium phosphate is separated from the sand and clay. The clays, now in a slurry mixture, are returned to the lands and …
