11.21 Phosphate Rock Processing - US EPA
11.21 Phosphate Rock Processing ... Phosphate rock mined in North Carolina does not contain pebble rock. In processing this type of phosphate, 10-mesh screens are used. Like Florida rock, the fraction that is less than 10 mesh is treated by 2-stage flotation, and the fraction larger than 10 mesh is used for secondary road building. The 2 major western phosphate rock ore deposits are located in ...
Phosphate Beneficiation Process
Large scale mining and processing of phosphate is essential for operating at a profit. In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the main ...

Processing - The Phosphate Risk
In Florida, after the phosphate rock is extracted, the ore is dumped into a pit at the mine site, and high-pressure water guns turn it into slurry. The slurry is pumped to a beneficiation plant. At the processing plant, the slurry mixture goes through a two-step process to separate the phosphate rock from sand and clay particles. The first stage is a concentrating process that separates the ...

Phosphate Rock | Minerals Education Coalition
Relation to Mining. Most phosphate rock is mined using large-scale surface methods. In the past, underground mining methods played a greater role, but their contribution to world production is declining. Often extraction operations supply feed to a nearby fertilizer-processing complex for the production of downstream concentrated fertilizer products. Currently, most phosphate rock production ...
Reserves and Resources DC World Phosphate Rock
IFDC estimates of world phosphate rock reserves and resources indicate that phos phate rock of suitable quality to produce phosphoric acid will be available far into the future. Based on the data reviewed, and assuming current rates of production, phosphate rock concentrate reserves to produce fertilizer will be available for the next 300-400 years. It should be stressed that reserves are ...

Phosphate Mining - The Mosaic Company
Phosphate rock is usually found 15-50 feet beneath the ground in a mixture of phosphate pebbles, sand and clay known as phosphate "matrix." The sandy layer above the matrix, called the overburden, is removed using electrically operated draglines. Equipped with large buckets, these draglines remove the overburden, placing it in the previously mined voids, and excavate the matrix, depositing it ...
The Mining Process - Welcome - The Phosphate …
In Florida, the phosphate rock is extracted by a process referred to as strip-mining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 30-40 feet below ground. Sandy topsoil, also known as overburden, is removed by large digging machines called draglines. The draglines can remove from 20 - 65 tons of overburden per dig, leaving 215 ft.-wide paths behind ...
