Coal: All present production is bituminous coal from the Cumberland Plateau and Cumberland Mountains regions. There is a sizable reserve of lignite in West Tennessee, more than a billion tons, but as yet there has been no mining. Coal production accounts for about 8.5 percent ($67 million) of Tennessee’s annual mineral production value.
Oil and Gas: Tennessee’s oil and gas production is small by national standards. Oil production currently totals about 350,000 barrels per year, down from more than one million barrels in 1982. Gas production was close to zero before 1977, when pipelines first reached the fields, but rose by 1984 to more than five billion cubic feet per year.
Ball clay: Tennessee is the leading producer of ball clay in the nation. Ball clay is used primarily in the manufacture of dinnerware, floor and wall tile, pottery, and sanitaryware, and accounts for about four percent ($29 million) of Tennessee’s annual mineral production value.
Zinc: Zinc is another mineral of considerable importance to Tennessee’s economy. Mines and mills are currently being operated in Grainger, Jefferson, and Knox Counties in East Tennessee, and in Smith County in Middle Tennessee.
Construction materials mined or quarried in Tennessee include dimension stone (sandstone and marble), crushed stone, limestone and clay for making cement, and sand and gravel. While some of these are considered to be mineral commodities, rather than minerals in the strictest sense, they are all a very important part of Tennessee’s mineral industry. Collectively, these materials account for more than 50 percent ($442 million) of the State’s annual mineral production value, and production of one or another (or several) occurs in virtually every county in the State.
