washing the mined phosphate with a hydraulic jet and then pumping it in liquefied "slurry" form to a washing plant. The phosphate was then mechanically graded by size, concentrated, and dried
They all involve the mechanized removal of rock.
In 2003, nine U.S. firms in four states mined phosphate rock ore, compared to 20 firms in 1997. In 2003 mines produced an estimated 33.3 million metric tons of phosphate rock, with a value of $895 million
The three types of surface mines are open-pit mines, strip mines, and mountaintop removal mines. Open-pit mines involve extracting minerals from a large, open excavation. Strip mines involve removing layers of soil and rock to expose the resource. Mountaintop removal mines involve removing the summit of a mountain to access the coal seams underneath.
Florida mines phosphate rock, oil, limestone, kaolin, and zircon.
Types of surface mining include open-pit mining, quarrying, strip mining, and mountaintop removal mining. These methods involve removing overlying vegetation, soil, and rock to access ore or minerals near the surface. Each type of mining has various environmental impacts that should be considered.

Phosphate is typically mined using large equipment to remove overlying soil or rock layers. The phosphate-rich material is then extracted and processed to separate the phosphate from other minerals. These phosphate deposits can be found in sedimentary rock formations and are commonly mined in open-pit mines.
Open pit mining and strip mining are both considered surface mining because they involve the removal of ore from near-surface deposits, rather than underground mining. Both methods use heavy machinery to extract minerals or resources by removing layers of soil, rock, or other materials that cover them.
The most common type of mining used to extract phosphates is open-pit mining. This method involves removing the overlying layers of soil and rock to access the phosphate deposits near the surface. Once extracted, the phosphates are processed and used in various applications such as agricultural fertilizers.
Strip, surface or open cast mining.
