Paper Chem & Tech of Gypsum ASTM Spec Tech Publ 861 1984 Oct; :116-139
In its role to provide technology to prevent or limit adverse environmental impacts associated with mining or minerals processing, the U.S. Bureau of Mines has conducted research at its Tuscaloosa Research Center to assess the environmental impacts of phosphogypsum produced by the Florida phosphate industry. Over the years, stockpiles containing 304 million metric tons of phosphogypsum have accumulated, and the industry continues to generate an additional 30 million metric tons per year. Samples from approximately 300 m of drill core, obtained from 9 stockpiles, were characterized. The data developed indicated that phosphogypsum is not a corrosive or toxic hazardous waste as defined by the environmental protective agency criteria.
