Florida Phosphate Mining History
Florida Phosphate Mining History. Florida Phosphate Mining History. Florida phosphate mining dates back to the first hard rock deposits found near Hawthorne in Alachua County in 1883. Endurance was imperative in the early years when phosphate mining was done with wheelbarrows, picks and shovels. Next came mule-drawn scrapers.
History Of Phosphate Mining In Florida Fraught With Peril
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.
