  263The Mineral Industry of 
Michigan 
This chapter has been prepared under a Memorandum of Understanding between
the Bureau of Mines, U.S. Department of the Interior, and the Geological
Survey Division, Michigan Department of Natural Resources, for collecting
information on all nonfuel minerals. 
By James J. Huh and L. J. Prosser, Jr.2 
The value of nonfuel mineral production in Michigan was $1.4 billion in 1978
and $1.5 billion in 1979. Leading nonfuel mineral commodities, in terms of
value, were iron ore, portland cement, sand and gravel, magnesium compounds,
and stone. Iron ore production, in the decade of the 1970's, accounted for
about 33% of the State's total 
nonfuel mineral value. During 1978 and 1979, Michigan was the Nation's leading
producer of calcium chloride, crude gypsum, magnesium compounds, and peat.
Other nonfuel mineral commodities produced were bromine, clay, copper, iodine,
lime, masonry cement, salt, silver, and sulfur.
