How phosphate is mined and processes Mining Sedimentary phosphate tends to be found in loose sediment, so it can be mined with dredge lines or picks and shovels . In Florida, the phosphate is found mainly in one layer of clay and sand that’s about 10-20 feet thick, and 15-50 feet below the surface.
Most mining of phosphate rock involves clearing large swaths of vegetation and digging up the soil beneath to reach the phosphate-ore-containing matrix 60 to 80 feet below the surface. This matrix is then transported by pipeline to a nearby plant, where the phosphate ore is forcibly separated from the sand and clay by a process known as “beneficiation.”
The specific processes used to extract phosphate rock depend on the geographic characteristics of the area in which the mineral deposits are lo ed. Most phosphate mining is conducted as open-pit mining rather than subsurface mining. In a typical mining operation, a layer of topsoil and other material is removed and placed into already-mined areas.
how phosphates are mined to produce phosphoric acid. Processing Phosphates for Use in the Fertilizer Industry. The dried phosphate ore is then most commonly processed into what are referred to as ammoniated phosphates. This is done by reacting the phosphate rock with sulfuric acid to produce phosphoric acid.

Phosphate Beneficiation Process. 06-05-2016 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.
