THE MINERAL INDUSTRY OF FLORIDA

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

In 2004, Florida's nonfuel raw mineral production was valued' at $2.32 billion, based upon annual U.S. Geological Survey (USGS)
data. This was a 12.1% increase from that of 20032 and followed a 2% increase in value in 2003 from that of 2002. The State ranked
fourth (fifth in 2003) among the 50 States in total nonfuel mineral production value, of which the State accounted for more than 5% of
the U.S. total.
Florida continued to lead the Nation in phosphate rock mining in 2004 by producing more than six times as much as the State with
the next highest production. Phosphate rock is produced in only four States. In terms of value, phosphate rock, crushed stone, cement
(portland and masonry), and construction sand and gravel continued to be the most important raw nonfuel mineral commodities
produced in Florida. The dollar value of these four mineral commodities and the next highest commodity, zirconium concentrates,
represented about 94% of the State's total nonfuel mineral value.
In 2004, nearly all of Florida's nonfuel mineral commodities increased in value. Portland cement and crushed stone led the way
with increases of $109 million and $83 million, followed by zirconium concentrates and masonry cement, up about $15 million each,
fuller's earth, up about $9 million, and construction sand and gravel, up $5 million. Smaller yet significant increases also took place
in phosphate rock, peat, industrial sand and gravel, and magnesium compounds. Only rutile showed a decrease, down about $3
million.
In 2003, the State's increase in value mainly resulted from increases in construction sand and gravel, up $27 million, portland
cement, up about $26 million, and masonry cement and crushed stone, up about $19 million each. These increases were partly offset
by decreases in the values of phosphate rock, down about $23 million, and fuller's earth and zirconium concentrates, down about $9
million each. Smaller yet significant decreases also happened for peat, rutile, industrial sand and gravel, and magnesium compounds
(descending order of change) (table 1).
In 2004, Florida continued to be the only State to process rutile and produce staurolite and remained first in the quantity of masonry
cement, peat, and phosphate rock produced. While the State continued to be first of two States that produced zirconium concentrates
and titanium mineral concentrates and third in crushed stone, it rose in rank to second from third in magnesium compounds, to fifth
from seventh in fuller's earth, and to sixth from seventh in portland cement. Additionally, Florida produced significant quantities of
construction and industrial sand and gravel.
The Florida Geological Survey3 (FGS) provided the following narrative information. Production and other data in the following text
are those reported by the FGS, based upon that agency's own surveys and estimates. The FGS data may differ from some production
figures reported to the USGS.

Employment

The Mine Safety and Health Administration (20044) reported that for calendar year 2004, 7,103 persons were employed in
Florida's mining operations; this number does not take into account contractors that may be working for some operators. The crushed
stone industry employed 3,307 workers, and the sand and gravel industry employed 2,626 workers, and the reminder of the workforce
was employed by cement, clay, phosphate, and other operations.

Exploration and Development

Expansion of phosphate mining has been proposed in west-central Florida (Hardee and Manatee Counties), to the south in DeSoto
County, and in northern Florida in Lafayette County, involving some 32,900 hectares (ha).
While sand supplies were adequate, the same was not true for cement and gravel and crushed stone. Cement and stone aggregates
continued to be imported to Florida, although not in quantities exceeding Florida's production levels. Industry standard distances
from the source to construction sites for the Nation commonly have an average transportation trucking range of 80 kilometers (km)
based on economics (National Stone, Sand and Gravel Association, 2005). In Florida, more than one-half of the crushed stone
aggregate comes from the southernmost part of Florida, in particular from Dade County. The remainder of Florida, then, is
experiencing progressively larger transportation distances for delivery of stone aggregates, commonly up to 240 km. This, in turn,
owing to increasing fuel prices, is elevating aggregate costs to the consumer. In northern Florida, although precise quantities are



The terms nonfuell mineral production" and related "values" encompass variations in meaning, depending upon the mineral products. Production may be measured
by mine shipments, mineral commodity sales, or marketable production (including consumption by producers) as is applicable to the individual mineral commodity.
All 2004 USGS mineral production data published in this chapter are those available as of December 2005. All USGS Mineral Industry Surveys and USGS Minerals
Yearbook chapters-mineral commodity, State, and country-also can be retrieved over the Internet at URL http://minerals.usgs.gov/minerals.
2Values, percentage calculations, and rankings for 2003 may differ from the Minerals Yearbook, Area Reports: Domestic 2003, Volume II, owing to the revision of
preliminary 2003 to final 2003 data. Data and rankings for 2004 are considered to be final and are not likely to change significantly.

unknown, stone aggregate is arriving by barges down the Mississippi River, and by rail and ships. In addition, a shortage in qualified
truck drivers is aggravating delivery accommodations, as is a shortage in qualified construction personnel in Florida's construction
boom. At the currently rising aggregate production levels and because of Florida's rapid population growth, it is anticipated that the
State's reserves might well be exhausted or in economic jeopardy in a relatively short period of time. The reasons include community
and environmental antimining sentiments, preemption of mining rights because of zoning or deed restrictions, and/or other litigation-
related land-use constraints.
Florida's mineral resources reach beyond those of terrestrial origin or siting, especially for Florida's excessively broad continental
margins in the Gulf of Mexico. FGS research on Florida's marine waters of the Gulf of Mexico has attained recognition by such
agencies as the Minerals Management Service (MMS). A significant number of investigations have, during the years, been published
or otherwise reported concerning offshore sediments of Florida's Gulf of Mexico. Balsillie and Clark (2001, p. 1) compiled a
comprehensive treatment of the subject in a regional, subregional, and Florida county-by-county basis for marine waters of Florida's
Gulf Coast. Their study was undertaken to identify what is known about potential sources of sediment for beach restoration and
maintenance renourishment and, perhaps, for other task-oriented requirements. They annotated publications and reports to the extent
that the user will have a grasp of the information and area of applicability of each included work.

Commodities Review

Industrial Minerals

With the understanding that Florida is among the four most population-gaining States, with some 25,500 new residents arriving
monthly, it is small wonder that basic materials to support infrastructure, commercial service-providing establishments, and housing
have, in turn, been affected. As in recent years, the construction industry has been hampered by an inadequate supply of materials, in
particular, in shortages of aggregates, cement, and steel. In 2004, the mining and processing of basic construction materials in Florida
(limestone or lime-rock aggregates whether termed gravel or crushed stone, sand, and cement) composed 55.5% of the total nonfuel
valuation of all mined mineral resources or mined commodities of the State.
Cement.-High-purity limestone is used to manufacture the clinker for masonry and portland cement. Florida was a major
producer and consumer of both types of cement in 2004. Whereas limestone is mined in a number of counties throughout the State,
cement clinker was produced only in Alachua, Dade, Hemando, and Suwannee Counties. Cement plants, which were just grinding
plants that used imported clinker, operated in Hillsborough and Manatee Counties. Rinker Materials Corporation, based in West Palm
Beach, FL, has acquired seven concrete plants and a small products distribution operation in the northwestern panhandle of Florida
(Crestview, Fort Walton Beach, Panama City, Panama City Beach, Pensacola, and Point Washington). Rinker officials have acquired
these to expand their operations into the State's northwest where the company has not previously had an operating presence. A Rinker
Corp. cement plant expansion is in the works in Hernando County, and three plants in Sumter County are in the permitting phase.
Clays.-Fuller's earth, common clays, and kaolin were mined in several locations in Florida in 2004. Fuller's earth, which was
mined in Gadsden and Marion Counties, is typically used as an absorbent material; kaolin, which was mined in Putnam County, is
used in the manufacture of paper and refractories. Common clays were mined mostly in Clay and Lake Counties and in small
quantities from various locations throughout the State.
Phosphate Rock.-In recent years, the Florida phosphate industry was controlled by some one-half dozen companies in west-
central counties of Florida (Hardee, Hillsborough, Manatee, and Polk). In 2004, however, only three companies controlled phosphate
rock mining in Florida: CF Industries, Inc., PCS Phosphates, and Mosaic Company, which acquired mining interests of Cargill, Inc.
and IMC Global, Inc. Nine phosphate rock mines were active in 2004, totaling some 122,000 ha, of which Mosaic Company
controlled 62.6%, or 75,300 ha.
In 2004, phosphate mining activities resulted in mineral products valued at 35.8% of Florida's total nonfuel mineral production.
Even so, Florida's production of phosphate rock, based on FGS estimates, accounted for approximately 75% of the U.S. production
and 25% of the world's production. FGS records indicate that some 28 million metric tons of phosphate rock was extracted from
Florida mines in 2004. Of note, in January, an important source of phosphate rock mining information, the Florida Phosphate
Council, was disbanded; its functions have been slated to be assumed by Mosaic Company, whose corporate offices are based in
Minnesota.

Metals

Titanium and Zirconium.-E.I. du Pont de Nemours & Co., Inc. and Iluka Resources, Inc. continued to operate heavy-mineral
sand mines in Baker, Bradford, Clay, and Duval Counties. Ilmenite, leucoxene, rutile, and zircon are the primary minerals of interest
in the heavy-mineral sand deposits of this region. Ilmenite, leucoxene, and rutile are the primary ingredients in the manufacture of
titanium dioxide pigments, which, in turn, are used in the manufacture of lacquers, paint, paper, plastics, and varnish. The major uses
of zircon are refractories, foundry sands, and ceramic applications.

Environmental Issues and Reclamation

In 2004, the Florida Department of Environmental Protection Bureau of Mine Reclamation issued 25 nonphosphate permits, largely
Environmental Resource Permits (ERP) and Wetland Resource Permits, accounting for 2,750 ha of upland and wetland disturbance

and mine expansions and modifications. Records indicate that 64% of land mined for phosphate has been reclaimed since July 1,
1975; mined phosphate totaled more than 68,800 ha with 44,500 ha having been reclaimed.
Since July 1, 1975, Florida has required that all mined lands be reclaimed, as administered by FDEP's Bureau of Mine Reclamation.
In the past 10 years, more than $325 million has been spent on mandatory as well as other related reclamation projects. Mined land
has been reclaimed for agricultural, commercial, industrial, recreational, residential purposes, and as sanctuaries for birds and other
wildlife. Since 1980, more than 30 million trees have been planted on reclaimed lands. The mining companies have also donated
thousands of hectares to State and public entities for recreation and wildlife habitat. The industry has continued to work with the
FDEP and other State and Federal agencies to protect and to restore ecosystems and to benefit wildlife.

Governmental and Related Programs

The erosional impacts of hurricanes Charlie, Frances, Ivan, and Jeanne on the coasts of Florida in 2004, resulted in resounding
responses from Federal and State Governments. In 2004, the Florida Legislature added an emergency appropriation of $68.4 million
to its $30 million annual expenditure level for beach restoration. These funds are, in part, used to cost-share with local governments
and with the U.S. Army Corps of Engineers funding of more than $160 million for some 15 Florida beach restoration projects. While
most of the funding is used in design phases, dredging and pumping activities, part of this total funding is used for conducting sand
search studies in offshore waters. Marine sources of sand for restoration work have been the norm for decades because upland sources
have become diminished and/or not economic.
The FGS and the MMS have entered into a multiyear cooperative agreement (cooperative agreement # 1435-0001-30757) with the specific
goal of locating and characterizing the areal extent and volume of available sands suitable for beach nourishment lying in Federal waters
adjacent to State submerged lands off the northeast coast of Florida. In the second year of this study, 306 km of seismic data were
collected offshore Nassau, Duval, and Flagler Counties (Florida Geological Survey, unpub. data). These data were subsequently
processed, interpreted, and integrated with the data collected in the first year. A total of 52 vibracores was collected offshore Nassau and
Duval Counties. Initial analysis of all vibracore data available for inclusion in FGS-MMS report infers potential reserves of up to 152
million cubic meters of restoration-quality sand offshore southern Duval County. It is anticipated that the analysis of planned
vibracores to be obtained for the third year report will facilitate the quality and quantity of potential reserves offshore northern Duval
County and all of Nassau County.
The fourth annual Mining Day took place at Florida's State Capitol in 2004. This event was jointly sponsored by the aggregates,
phosphate, heavy-minerals, and clay industries in Florida in an attempt to bring awareness of the importance of mining to
decisionmakers. Also participating were representatives with presentations from the FDEP's Bureau of Mine Reclamation and the
FGS. Some 21 legislative offices were represented, and participants answered inquiries about what makes mining the "backbone of
Florida's future" (Florida Limerock and Aggregate Institute, 2004).
The aggregates industry, principally through the Florida Limerock and Aggregate Institute, has been instrumental in conducting a
public education program in the elementary schools of Florida communities (Florida Limerock and Aggregate Institute, 2004). This
program has received the approval of the State's Department of Education science curriculum section. The program goal is to
enhance the science curriculum with more mineral science and mining recognition at the fourth grade level. It is currently targeted to
mining areas where the children can be educated as to the work their parents perform and importance of local resources. The program
is supported by volunteers from local aggregate mining companies who will donate classroom materials and provide mentoring
assistance. In 2004, four schools were engaged in Clermont and Lake County, and five schools, three gifted programs, and a county
board of education were engaged in Brooksville, Hemando County. More information about this program and its success can be
found on the Web site at URL http://www.flai.org.
As part of an ongoing cooperative effort through the STATEMAP component of the National Cooperative Geologic Mapping
Program (a USGS-State of Florida-FGS jointly funded program), in 2004, the FGS completed geologic mapping for the eastern
portion of the USGS 1:100,000-scale Gainesville quadrangle and completed the final maps and cross sections for the same area. The
completed maps and cross sections are available as part of the FGS Open-File Map Series (Evans and others, 2004).
