The Sarasota County Phosphate Prospect is in North Port, Florida. Historically the site has been part of the Sarasota Phosphate Mining District. The site was first discovered in 1962. Preliminary development has taken place such as surface trenching, adits, shafts, drill holes, geophysics, geochemistry, or geological mapping.

The top phosphate-producing states, Florida and North Carolina, accounted for over 75 percent of domestic output. The other 25 percent of US production came from Southeast Idaho and Utah.

The Florida Sierra Club Phosphate Committee serves as a watchdog in its effort to monitor the activities of mining companies. It works in cooperation with other like-minded organizations to hold mining companies accountable for any accidents or toxic releases which may harm the environment, water bodies, wildlife or residents of Florida.

In Florida habitat loss is a significant issue, particularly for at-risk species such as the tiny oval pigtoe mussel — which relies on clean water to survive — and the large, iconic Florida panther. Most mining of phosphate rock involves clearing large swaths of vegetation and digging up the soil beneath to reach the phosphate-ore ...

of the Florida Peninsula, may contain a few parts per million, however, and the highly saline alkaline lake waters (such as Searles Lake, Calif.) contain 200-900 ppm. The ocean as a whole is nearly saturated with phosphate, and an amount equivalent to that brought by rivers is precipitated

Phosphate deposits in Florida are among the richest and most accessible in the world. Although there are several theories about how the deposits were formed, many experts believe the ocean covered what is now Florida about 10 million years ago. Phosphate ore …

Central Florida's landscape is torn up by phosphate mining to feed global demand for industrial fertilizers. Mining phosphate ore and turning it into fertilizer leaves behind a big mess in the ...

The role of sodium silicate in the anionic flotation of a Florida phosphate ore was investigated using laboratory continuous flotation tests, frothability tests and SEM observations.

Phosphate Beneficiation. Background. Definition of "Beneficiation": This is the second step in the mining process, after removal of the ore from the ground. Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other.

Fluoride Pollution from Phosphate Industry in Polk County, Florida. Between 1953 and 1964, an estimated 150,000 acres of cattle land were abandoned as a result of the phosphate industry's fluoride pollution, and 25,000 acres of citrus groves in the county were damaged.

A "matrix" of phosphate ore, clay and sand is exposed, and that mixture is pulverized into a slurry and sent via pipelines to a nearby plant that separates out the phosphate…

Phosphogypsum is the radioactive waste from processing phosphate ore into phosphoric acid, which is predominantly used in fertilizer. Manatee County officials have issued evacuation orders for the area surrounding Florida's Piney Point in anticipation of the imminent catastrophic collapse of a phosphogypsum stack retention pond holding up to ...

Unfortunately, Florida's phosphate industry official's direct operations daily to strip all things mentioned above from the landscape for phosphate ore, which leaves toxic wastelands for someone else to neutralize. The Myakka River and watersheds region in southwest central Florida has a population of over five-hundred thousand citizens.

Florida has 178 identified mines listed in The Diggings™. The most commonly listed primary commodities in Florida mines are Iron, Phosphorus-Phosphates, and Uranium . At the time these mines were surveyed, 15 mines in Florida were observed to have ore mineralization in an outcrop, shallow pit, or isolated drill hole—known as an occurance ...

It's the biggest phosphate company in the world and a major presence in Florida. Mosaic is currently mining phosphate rock on more than 70,000 of the 380,000 acres it owns in Manatee ...

Florida phosphate ore is almost like a placer deposit or an agglomerate, compacted, and is typically referred to as "Phosphate Rock". The actual ore consists of Fluoapatite, silica and clay. Generally, it breaks up into fairly sand size particles and finer as soon as it is pumped through the centrifugal pumps used to transport it to and through ...

However, phosphate industry officials are intent on completely eradicating west central Florida's unique ecosystems for the phosphate ore just beneath the surface. In the recent past, news about the environmental devastation being caused by Florida's phosphate industry is spreading to communities all around central Florida.

Phosphate Strip Mining P hosphogypsum is the hazardous waste byproduct created when phosphate ore is processed into fertilizer. It is stored in mountain-like structures called gypstacks that can reach 200 feet or more. These radioac-tive stacks, which re-circulate acidic process water, will be here forever. Florida will have to

The phosphate ore (matrix) found in Florida typically . lies beneath a 15- to 50-foot layer of soft, sandy, or clayey overburden material. Therefore, phosphate mining in Florida requires that the overburden material be stripped off to expose the phosphate matrix. The phosphate matrix .

Please note that figures indicate that seventy three percent (73%) of the land mined or disturbed for phosphate since Ju ly 1, 1975 have been reclaimed.

Phosphate Mines. Description. The central phosphate region of Florida has been strip mined since 1888. By the 1980s, it accounted for almost 30% of worldwide production, and almost three quarters of U.S. production. 93% of Tampa Bay's exports are phosphates. Almost all mined phosphate …

The phosphate deposits occur near the top of the sequence in the Hawthorn Formation of middle Miocene age which overlies and confines the major aquifer used as a source of ground water throughout the northern Florida-

The Florida phosphate deposits are the most productive in the world. About 1 billion tons of phosphate­ ... Ore from the higher grade and more uniform land-pebble deposits became the mainstay of the phosphate market, and river-pebble mining ceased early in the 20th century.

Florida phosphate production depends on strip-mining, which results in the excavation of thousands of acres annually. Removal of the phosphate ore (matrix) from the ground causes a deficit in the volume of materials available for land reclamation. Restoring the landscape to near pre-mining elevations necessitates the creation of lakes, and mine ...

The major useful component of phosphate ore is phosphorus in the form of the phosphoric anhydride P 2 O 5. The P 2 O 5 content in phosphate ores varies from 2–6 to 25–34 percent, depending on the processing behavior, mining and geological conditions, and other factors.

The Bureau of Mines, US Department of the Interior, conducted studies to recover phosphate from four dolomitic southern Florida deposits not currently mined. The samples contained 5.8–10.2% P2O5 and 1.7–4.8% MgO. Chemical analyses of sized fractions indicated that no pebble concentrate, +1.2 mm (+ 14 mesh) could be produced from these samples. A scheme was developed that consisted of ...

Phosphorite, or phosphate rock, is the raw material of phosphoric acid production. It has also been regarded as the most important secondary rare earth element (REE) resource due to low contents of rare earth elements contained in the ore. In Florida, there is about 19 Mt of phosphate rock mined annually. After beneficiation, the phosphate rock concentrate is utilized to produce phosphoric ...
