The South Carolina phosphate mining industry began after the Civil War and dominated world production in the 1880s. Mining began in late 1867 on plantations near Charleston after the gentlemen-scientists Francis S. Holmes and St. Julien Ravenel and the chemists N. A. Pratt and C. U. Shepard discovered that local "stinking stones" …

Fluoride has been, and remains to this day, one of the largest environmental liabilities of the phosphate industry. The source of the problem lies in the fact that raw phosphate ore contains high concentrations of fluoride, usually between 20,000 to 40,000 parts per million (equivalent to 2 to 4% of the ore).

In the phosphate industry, phosphoric acid is a major component in the manufacture of fertilizers. It is mainly produced by the digestion of phosphate ore by a concentrated sulfuric acid solution. The products are phosphoric acid and solid gypsum, which are separated in a vacuum filtration unit downstream of the digestion tank (Becker, 1983 ).
