THE MINERAL INDUSTRY OF FLORIDA

This chapter has been prepared under a Memorandum of Understanding between the U.S. Bureau of Mines, U.S.
Department of the Interior, and the Florida Geological Survey for collecting information on all nonfuel minerals.


Florida ranked sixth among the 50 States in total
nonfuel mineral value' in 1994, climbing from 8th in 1993,
according to the U.S. Bureau of Mines. The estimated
value for 1994 was $1.5 billion, an 12% increase over that
of 1993. This followed a 9% decrease in 1993 from that of
1992. The State accounted for 5% of the U.S. total value
and continued to lead significantly the other U.S. States in
phosphate rock production and value. The total value
decreased in 1993, mainly due to a drop in phosphate rock
values. But the rebound in 1994 was attributed to a
combination of increased values for phosphate rock,
crushed stone, construction sand and gravel, and masonry
cement. The latter three commodities have increased
consistently during the last 3 years. Florida, almost
exclusively an industrial mineral producing State, remained
first in the production of phosphate rock, masonry cement,
peat, titanium concentrates, and metal; second in rare-earth
concentrates and fuller's earth clay; and third in crushed
stone and magnesium compounds. The State rose from
sixth to fifth in portland cement production. Compared
with 1993, the value of phosphate rock, crushed stone,
construction sand and gravel, masonry cement, industrial


sand and gravel, and peat increased in 1994. Decreases
occurred in the value of portland cement, common and
kaolin clays, and the rare-earth metal concentrates.
In 1994, the phosphate industry rebounded somewhat
from significant production and value drops in 1993-one
of the most difficult of recent years. Production of
phosphate rock, primarily used to manufacture fertilizer,
increased moderately in 1994 and some previously closed
operations were able to reopen. Consumption increased
substantially, especially for diammonium phosphate, in
large part to supply increased export demands. The
industry continued research to develop technologies that
would enable mining companies to further reduce the need
for deep-aquifer water. Presently, the industry recirculates
about 80% of the water it uses in certain manufacturing
processes. Limestone production was moderately up in
1994 compared with that of 1993; this was due, in part, to
increased highway and residential construction.
Compliance with the 1990 amendments to the Clean Air
Act (CAA) was a controversial issue for mining facility
operators who were required to obtain permits for work
already in progress in addition to all new work, according
