II.3.a Phosphate Rock Mining The phosphate mining industry in Florida, mine a rock described as "land pebble."The amount of arsenic associated with limestone mining was computed by multiplying the weight of limestone mined by its arsenic concentration.
Phosphate Mining Linked To Sinkholes. Sinkholes form in central Florida's landscape due to groundwater reserves such as aquifers insidiously being destroyed by watershed destruction via phosphate strip mining operations. This is because the water contained in the aquifers hydraulically sustain the weight of the surface above.

Phosphate rock is a general term referring to rock with high concentrations of phosphate minerals, most commonly those of the apatite family with the general formula Ca 5 (PO 4 CO 3) 3 (F,OH,Cl). Ninety percent of phosphate mined is used to produce chemical fertilisers.
Mineral Mining and Processing Effluent Guidelines. EPA promulgated the Mineral Mining and Processing Effluent Guidelines and Standards ( 40 CFR Part 436) in 1975, and amended the regulation in 1976, 1977, 1978, and 1979. The regulation covers wastewater discharges from mine drainage, mineral processing operations and stormwater runoff.

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 white Coquina Limestone overlies the rich phosphate ore and is in stark contrast to the underlying colored phosphate ore. The phosphate ore contains a variety of abundant fossils that range from microscopic one-celled animals known as foraminifera up to some of the largest whale fossils and sharks teeth ever found.

Limestone and dolomites presently mined in the State of Florida range in age from late Middle Eocene (42 million years ago, MYA) to Pleistocene (.5 MYA). The mining in the Florida panhandle and the western half of the northern and central peninsula utilizes carbonates that range in age from late Middle Eocene to Upper Oligocene and Middle Miocene.
1 The public meeting on the proposed mine was held in Arcadia, the county seat of DeSoto About two dozen people spoke out Tuesday against Mosaic's plan to mine phosphate in DeSoto County. No one told county commissioners they support the mine, …
The Guidebook does not discuss the mining of ores that are extracted using strip mining methods, including aluminum (bauxite), phosphate, and uranium. The Guidebook also does not discuss mining involving extraction of coal or aggregates, such as sand, gravel, and limestone.
Limestone mining began in Florida during the First Spanish Period. In 1672, construction began on the Castillo de San Marcos in St. Augustine. Locally mined coquina was used. This is the oldest masonry fort in the continental United States. In 1753, construction began on a limestone fort in St. Marks to replace older wooden structures.
The hard-rock phosphate deposits seem to have been formed by very thorough ground-water leaching of phosphate from marine phosphorite beds and redeposi tion of phosphate at depth as secondary apatite by replacement of limestone and precipitation in cavities, as proposed by some earlier investigators.
Almost all phosphorus is mined as phosphate rock (PO4). Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the world's largest phosphate deposit is the Phosphoria Formation, located in southeast Idaho.
In 2015, 27.6 million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and Morocco.The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion.. As of 2015, there are 10 active phosphate mines in four states: Florida, North Carolina, Idaho, and Utah.

This research was focused on selection and identification of phosphate-potassium solubilizing bacteria and quantitative estimation of P and K solubilized by bacteria isolated from the area around the limestone mining of Cirebon Quarry. This research was conducted in relation to the effort of limestone mining reclamation. MATERIALS AND METHODS
Phosphate Mining. The Lexington Limestone contains unusually high concentrations of phosphate ( Cressman, 1973 ). Phosphate minerals occur in most members of the Lexington Limestone, principally the Tanglewood, Millersburg, and Grier Limestone…
In Morocco, there are many sedimentary phosphate mines that produce large quantities of phosphatic limestone wastes (PLW) that contain calcite (46 wt%) and dolomite (16 wt%). These mines are located near contaminated sites, such as the abandoned Kettara pyrrhotite mine. The surface drainage water at the Kettara mine site has a pH of 2.9–4.2 and elevated concentrations of SO4 (from …
The intercalating limestone layer is then blasted and removed to expose the phosphate bed, which is loaded onto trucks. Dredge mining uses bucket wheel excavators, draglines, scrapers, shovels and dredges. The three major methods of hauling materials in phosphate mining are pumping, trucking and transporting using conveyer belts.
Others were limestone, copper, phosphate, cobalt, steel, etc. The mining industry boomed during the British colonial administration, who, in …
Phosphate is often a limiting nutrient in many freshwater and coastal ecosystems located in carbonate terrains (Fourqurean et al., 1992, Reddy et al., 1995). Phosphate limitation exits in the freshwater wetlands and coastal bays of south Florida where the values of PO 4 3-are typically less than 0.05 μmol/L (Boyer et al., 1999).
This study examined musculoskeletal injury risk at four mining sites: underground coal, underground limestone, surface copper, and surface phosphate. Each site offered opportunities to investigate musculoskeletal disorder (MSD) injury risks and how those risks might be identified and categorized.

Phosphate pit lakes also generally have a smaller surface area and less "shallow zone" than most natural Florida lakes. Most phosphate mine pit lakes are similar in mean depth to natural Florida lakes (3 m–4 m), though their maximum depth is usually substantially greater (Boody et al. 1985a; Boody et al. 1985b).
