The Process of Phosphate Mining in Florida Phosphate mining in Florida is a strip-mining process. Overburden, the layers of material above the phosphate, is removed to expose the phosphate reserve (matrix). Before mining, exploratory cores are taken to measure the depth of the overburden and the thickness of the phosphate matrix. This coring

Description. The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

Nov 02, 2017 The phosphate mining carried out partly by Nauru, but mostly by Australian and British companies, had rendered most of the island both uninhabitable and infertile (about 80% of the surface of the island) by the 1960s, leaving everything but the coastal strip uninhabitable (Klein 2014). With a rise in sea levels due to global temperature rise ...

Digging the phosphate out of the ground is only one step of the mining process. Phosphate comes out of the ground as part of a matrix, which is a mix of the phosphate, sand and clay. The phosphate must be separated from the sand and clay it has melded with in the ground over millions of years.
