Four Corners Lonesome Mine_DEP Staff Jessica Duke_Dragline Phosphate Mining HPB4.jpg Florida's Phosphate MinesThere are 27 phosphate mines in Florida, covering more than 450,000 acres. Nine phosphate mines are currently active. Nine mines are 100 percent reclaimed and released from reclamation obligations. The remaining mines are either not started or are shut down.

The Phosphate Class is made up of minerals with a basic chemical unit of tetrahedral (AO4) groups with a negative three (-3) charge.The A can be either Phosphorus, Arsenic, Vanadium or Antimony. The basic chemical unit can be combined with metal ions on a one to one ratio or usually in more complex combinations with other ions such as hydroxide groups (OH), uranyl groups (UO2), a halogen or ...

Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine; silicon, arsenic or vanadium replace the phosphorus (and carbonate replace the phosphate group); and strontium, lead, and other elements substitute for the ...

With the commercialization of phosphate fertilizers since the early part of the 19th century, phosphate minerals have assumed an important role in industrial chemistry and agriculture. Clearly, the study of phosphate minerals is important from the economic, agricultural, environmental and (human and animal) health viewpoint.

one tenth of one percent of the mass of the earth's crust. Common mineral forms of phosphorus include apatite, wavellite, vivianite, and phosphorite. The most important sources of phosphorus are phosphorite or phosphate rock. Phosphate rock consists of the mineral apatite, an impure tricalcium phosphate, mixed with clay and other elements.

The production of phosphate mineral fertilizers is one of the most profitable and financially stable among manufacturing industries. Phosphate ore (apatite) is converted into fertilizer with sulfuric acid and phosphogypsum is a by-product of this process. Approximately 5 tons per ton of P 2 O 5 is produced. Rock phosphate is a naturally occurring source for P 2 O 5.

Phosphate minerals comprise only a fractional percentage of the soil mass, perhaps averaging 0.02% or so, which impedes their direct identification by optical microscopy and x-ray analysis unless their concentration has been locally increased by addition of phosphate fertilizers. In some cases, beneficiation of native phosphate minerals is ...

Next, the phosphate is extracted and purified. Few phosphate deposits are pure enough for the separation process to be eliminated. The specific process used to separate phosphate from other minerals varies based on the exact composition of the ore. In most cases, however, water is used to turn the rock into mineral slurry, from which a ...

What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO 4,SiO 4).It usually occurs in small isolated grains, as an accessory mineral in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss.These grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.

Phosphate rock refers to unprocessed ore and beneficiated concentrates that contain some form of apatite, a group of calcium phosphate minerals. Apatite in phosphate rock is the primary source for phosphorus in phosphate fertilizers. More than 80 percent of the world's current production of phosphate rock is mined from sedimentary deposits, which were formed by the deposition of phosphate ...

Phosphate Mineral. Phosphate minerals are natural sources of thorium, uranium, and uncommon metals and are also used in the radiochemical methods of separation of fissile materials from irradiated nuclear fuel and processes of "excess" weapon plutonium conversion into the mixed oxide fuel (MOX) for the nuclear reactors of new generation.
