Phosphate mining in South Carolina declined rapidly in the 1890s, when mining of the higher-grade deposits in central Florida began. The central Florida district has provided the majority of US phosphate ever since. US production of phosphate rock peaked in 1980 at 54.4 million metric tons.
There, high-pressure water guns turn the material into a watery mixture called slurry, which is sent through pipelines to a processing facility, referred to as a beneficiation plant, where phosphate rock is physically separated from the sand and clay in the matrix.

The majority of mining operations in Florida handle only the beneficiation ...
Phosphate Beneficiation. Background. Definition of "Beneficiation": This is the second step in the mining process, after removal of the ore from the ground. Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other.
phosphorus production. MATERIALS & METHODS Life Cycle Assessment (LCA) is a standardized systemic and systematic method for assessment of the potential environmental impact of a product or process over its entire life cycle, i.e. from extraction of raw materials to waste management (ISO 14040, 1997; ISO 14041, 1998; ISO 14042, 2000).
Phosphate rock (PR) is the raw material used in the manufacture of most commercial phosphate fertilizers on the market. With access to large, high-quality reserves of phosphate rock, Morocco, China and US are the most important players in phosphate industry.

Energy and Environmental Profile of the U.S. Mining Industry 8 Phosphates The element phosphorus, a nonmetal, is relatively rare in nature. In fact, phosphorus is less than one tenth of one percent of the mass of the earth's crust. Common mineral forms of phosphorus include apatite, wavellite, vivianite, and phosphorite.
The A$73-billion (US$52-billion) global phosphate market continues to grow as demand for fertiliser increases to meet food production needs. CSIRO team leader, Keith Barnard, said the CSIRO-developed PyroPhos process offers a simpler, safer and more efficient alternative to conventional phosphate production processes.

Rock phosphate deposits contain many million tonnes of uranium, which may be extracted as a by-product of making fertilisers. Some 20,000 tonnes of uranium has already been obtained from these rock phosphate deposits, but the process became uneconomic in the 1990s. Higher uranium prices and process refinements have changed the economic situation.
