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. Mechanized excavation began between 1900 and 1905 with steam shovels. Early steam shovels held only one cubic yard of earth,

Floripedia: Production of Phosphate Rock in Florida During

The production of phosphate rock in Florida during 1910 exceeds that of any preceding year, the output having for the first time reached and passed the landmark of 2,000,000 tons. The total production for 1909 was 1,862,151 tons while for 1910 the production was approximately 2,029,797 tons. This large output is more remarkable in view of the depressed prices for phosphate which prevailed

Phosphate rock is usually found 15-50 feet beneath the ground in a mixture of phosphate pebbles, sand and clay known as phosphate "matrix." The sandy layer above the matrix, called the overburden, is removed using electrically operated draglines. Equipped with large buckets, these draglines remove the overburden, placing it in the previously mined voids, and excavate the matrix, depositing it

Previously, significant amounts of rock were shipped to China, where it was processed into phosphate fertilizer. The majority of phosphate mining in Florida is done in the Peace River watershed. Phosphate mining companies use draglines to remove surface soils up to 60 feet (18.29 m) deep over thousands of contiguous acres. Once land is mined

Questions and Answers Florida Phosphate Mosaic :

It is produced when the phosphate rock we mine is combined with sulfuric acid to form phosphoric acid and phosphogypsum. The phosphogypsum must be filtered and removed so the remaining phosphoric acid can be used to make fertilizer. The phosophogypsum is subsequently deposited on a gypstack under strict standards established by the Florida Department of Environmental Protection

Florida Phosphate Rock Quandary Florida Mines

Florida Phosphate Rock Quandary Many years ago, the ocean flooded an ancient land mass today we call Florida and a layer of sand and clay rich in tiny phosphate particles were deposited. There are only few areas of phosphate deposits in the United States. In fact, central Florida is estimated to contain 75-80 percent of the continental United States phosphate deposits.

A Closer Look Into Florida's Phosphate Mining Industry

Phosphate rock is mined and then manufactured through the fertilizer manufacturing process. A typical Florida phosphate mine gets about 9,000 tons of phosphate rock per acre of land. Huge draglines are brought in and can remove the Florida earth from the surface down 100 feet in order to remove the entire matrix “field”. The phosphate industry refers the removed earth as “overburden
