873The Mineral Industry of Wyoming 
This chapter has been prepared under a cooperative agreement between the
Bureau of Mines, U.S. Department of the Interior, and the Geological Survey
of Wyoming for collecting information on all minerals except fuels. 
 
 
By H. C. Meeves 1 and William C. Henkes2 
 
 
 Mineral-production value in Wyoming reached an alltime high of $530.7 million
during 1967, an increase of $6.3 million over the $524.4 million reported
in 1966. Mineral fuels increased 2 percent and accounted for $412.7 million
of the total. 
 Increased values were reported for coal, gem stones, lime, LP galses, natural
gaso 
line, petroleum, pumice, sand and gravel, sodium carbonate, sodium sulfate,
uranium, and vermiculite. Decreased values were reported for cement,cIays,
feldspar, gypsum, iron ore, marketed natural gas, phosphate rosk, stone,
and vanadium.
