    Phosphorite typically contains more than 3% fluoride, in the mineral fluorapatite. Only a small amount is recovered. In 2015, fluorosilicic acid equivalent to 114,000 tons of fluorite(fluorspar) was produced as a byproduct of phosphate rock processing. This material represented nearly all the US production of fluoride, which is subsequently converted to fluorine. The produced fluorine is used to prepare polymers, pharmaceutical

  • History The Phosphate Risk

    History of Phosphate in Florida. Florida phosphate mining dates back to deposits first found in Alachua County, near Hawthorne, in 1883. In the early years, phosphate ore was collected out of the river by hand. Very soon, the mining was done the hard way with picks, shovels, wheelbarrows, strong backs, and sweat. Next came mule-drawn scrapers.
