Fluorine recovery in the fertilizer industry – a review.
The fluorine compounds liberated during the acidulation of phosphate rock in the manufacture of phosphoric acid and fertilizers are now rightly regarded as a menace, and the industry is now obliged to suppress emissions of fluorine-containing vapours to within very low limits in most parts of the world. As with any pollution control operation, it is highly desirable for the operator of the fluorine scrubbing operation to find a use or market for the recovered fluorine to help defray at least partially the cost of the operation.

Fluoride Pollution from Phosphate Industry in Polk County, Florida
Between 1953 and 1964, an estimated 150,000 acres of cattle land were abandoned as a result of the phosphate industry’s fluoride pollution, and 25,000 acres of citrus groves in the county were damaged. Truck crops were lost, and the commercial gladiolus industry in an adjacent county was blighted. In the seven-year period between 1953 and 1960, the cattle population of Polk County dropped 30,000 head.

The Phosphate Fertilizer Industry: An Environmental Overview
1. Introduction They call them “wet scrubbers” – the pollution control devices used by the phosphate industry to capture fluoride gases produced in the production of commercial fertilizer. In the past, when the industry let these gases escape, vegetation became scorched, crops destroyed, and cattle crippled. Today, with the development of sophisticated air-pollution control technology, […]
