Chapter E: History and Overview of the U.S. Diatomite Mining Industry, with Emphasis on the Western United States

January 1, 2003

The United States is the largest producer and consumer of diatomite in the world. In 2001, the United States produced about a third of the estimated global production of 1.95 million
metric tons (Mt) of diatomite (Dolley, 2003). In any given year, the United States accounts for at least 50 percent of all the diatomite exported in the world (Roskill, 1994). Seven diatomite companies operating in the United States produce diatomite in various grades for a range of applications, including
filtration, absorbents, fillers, insulation, and cement manufacture.
Economic deposits of diatomite within the United States depend on variations in the physical and chemical properties between and within deposits, potential end uses, and proximity to suitable markets. On the basis of historical production
figures, estimated U.S. diatomite-production capacity is currently about 800,000 metric tons per year (t/yr).
