  277The Mineral Industry of 
Minnesota 
This chapter has been prepared under a Memorandum of Understanding between
the 
Bureau of Mines, U.S. Department of the Interior, and the Mineral Resources
Research 
Center, University of Minnesota, for collecting information on all nonfuel
minerals. 
By James H. Aase' and Wanda J. West2 
The value of nonfuel mineral production in Minnesota for 1978 and 1979 was
$1,725 million and $2,068 million, respectively. The increase in value of
the 1978 production over that of the previous year was attributed to a rebound
from a 138-day steelworkers' strike in the State's iron ore mining industry
in 1977, coupled with rises in the unit values for iron ore and other mineral
commodities. 
Nationally, Minnesota was first among the States in value of nonfuel mineral
production in 1978 and second in 1979. Production in 1978 was reported from
approximately 550 operations located in 83 of the State's 87 counties. St.
Louis County maintained its lead in terms of mineral quantity and value output.
Mineral production valued in excess of $1 million was recorded in 25 counties.
Two metallic and seven nonmetallic mineral commodities were produced in Minnesota
during 1978 and 1979. Iron ore ranked first in terms of value, exceeding
the second
