  133The Mineral Industry of 
Florida 
This chapter has been prepared under a Memorandum of Understanding between
the Bureau of Mines, U.S. Department of the Interior, and the Florida Bureau
of Geology for collecting information on all nonfuel minerals. 
By James R. Boyle1 and Charles W. Hendry, Jr.2 
The value of nonfuel mineral production in Florida in 1978 and 1979 was $1.1
billion and $1.3 billion, respectively. The State ranked first in the production
of phosphate rock and titanium concentrates, and second in fuller's earth
and peat. Staurolite and zircon concentrates were produced only in Florida.
Nonmetals accounted for nearly all of the State's total mineral production
value in 1978 and 1979. The principal nonmet 
als produced, in order of value, were phosphate rock, stone, cement, sand
and gravel, and clays. All commodities, with the exception of magnesium compounds,
staurolite, and zircon concentrates, registered an increase in production
and value. Except for titanium concentrates and zircon concentrates, all
commodities registered an increase in unit value.
