  571The Mineral Industry of 
Wisconsin 
This chapter has been prepared by the Bureau of Mines, U.S. Department of
the Interior, and the Geological and Natural History Survey of Wisconsin,
under a Memorandum of Understanding for collecting information on all nonfuel
minerals in the State. 
By James J. Hi1P and Thomas J. Evans2 
 The value of nonfuel mineral production in Wisconsin was $159.2 million
in 1978 and $179.7 million in 1979. The increase in value primarily reflects
inflationary pressures that have caused the unit values of most mineral commodities
to escalate along with other products in the State's economy. 
 Nonmetallic minerals, especially sand and gravel and crushed stone used
for construction, continued to dominate the mineral scene in quantity and
value. 
 In the 1978-79 biennium, iron ore was the leading metallic mineral commodity
produced in Wisconsin. Witl~ the closing of Eagle-Picher Industries' zinc
mine in October 1979, iron ore became the sole metallic mineral produced
in the State. 
 Although three massive sulfide deposits have been discovered in the State
since 1968, only one is currently being evaluated for production purposes.
