Fuller's Earth Mines
The
Mining and Minerals Regulation Program, administers the laws and regulations related to the
reclamation of mined land and the protection of water resources (water
quality, water quantity and wetlands) at fuller's earth mines.
What is fullers earth?
Fuller's earth has been used for its absorbent properties since
ancient times. It was used by "fullers" to "full"
(remove) grease and fat from woolen cloth. Fuller's earth is a general
term that can be applied to many types of clay that have an
exceptional ability to absorb coloring materials from oils of animal,
vegetable, and mineral origin. In Florida, the term is narrowly
limited. Subsection 378.403(6), Florida Statutes, defines fuller's
earth as clay possessing a high absorptive capacity consisting largely
of montmorillonite or palygorskite. Fuller's earth clay includes
attapulgite.
Who is mining fuller's earth in Florida?
Fuller's earth mining began in Gadsden County in 1895. This ore
deposit extends from Gadsden County into Decatur and Grady Counties,
Georgia. One mine is operating in Marion County.
How is fuller's earth mined in Florida?
Fuller's earth occurs as a clay stratum. Over this stratum is a
sand and clay overburden lacking marketable material. At some
locations, there may be a second, deeper fuller's earth stratum. The
two fuller's earth strata are separated by overburden.
Prior to mining the trees are harvested by normal silvicultural
practices. Topsoil is removed and stockpiled along the edge of the
mine for later use in reclamation. The overburden is removed by
dragline, bulldozer, or pan scrapers and stocked piled for use in
reclamation. The fuller's earth is removed by dragline and loaded onto
trucks for transport to the processing plant. The mined out areas are
then backed filled with overburden, recontoured, covered with topsoil,
and revegetated to meet reclamation standards.
