By Karl E. Starch1 The value of nonfuel mineral production in Wyoming was $493 million in 1978 and $590 million in 1979. With about 3.5% of the total value of nonfuel minerals produced nationwide, Wyoming ranked ninth among the States in nonfuel mineral production in 1978 and 14th in 1979. Twelve nonfuel minerals were produced in the State during the biennium, 11 nonmetalics, and 1 metal. Sodium carbonate (trona) was the most important nonfuel mineral produced in terms of value, followed at considerable distance by bentonite and iron ore. These three commodities combined accounted for more than 90% of the value of all nonfuel minerals produced in Wyoming in 1978-79.
