byproducts of phosphate mining

Phosphate mining in the United States - Wikipedia

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
