us422a method of pumping and processing phosphatethe invention relates to the broad subject of dewatering phosphate clay wastes and has for its primary object the drainage of existing phosphate slime settling ponds and the reclamation of the drained ponds through the use of the processed slime as a land fill having adequate drainage characteristics. another object of the invention is to provide a processing step for phosphatepayne creek phosphate mine near fort green, florida thehistorically the site has been part of the polk phosphate mining district. the payne creek phosphate mine was closed at the time of data entry with no known plans to reopen. mine operations consist of surface workings extending 1,6.00 hectares (4,003.10 acres). there is one known shaft. the mining methodphosphate rock an overview sciencedirect topics9.2.1.2 norm from phosphate mining. phosphate fertilizers are obtained from phosphorites of sedimentary or magmatic origin. sedimentary phosphate rock usually is stripmined and containsphosphate mining sierra clubphosphate mining companies own or have mineral rights to over 400, acres, mostly in the peace and myakka river watersheds, with mining projects planned for over 62, acres. approximatelyhow does phosphate mining work? wuft newsnov , · according to the fdep, this layer is made up of phosphate rock, clay and sand. the phosphate is then mixed with water using highpressure water guns to create a slurry.estimated reading time 3 minsmethod 365.1, revision 2.0 determination of phosphorus bymethod 365.1 determination of phosphorus by automated colorimetry 1.0 scope and application 1.1 this method covers the determination of specified forms of phosphorus in drinking, ground, and surface waters, and domestic and industrial wastes. 1.2 the methodswhat is involved in phosphate mining? (with pictures)most phosphate mining is conducted as openpit mining rather than subsurface mining. in a typical mining operation, a layer of topsoil and other material is removed and placed into alreadymined areas. large dragline excavators then extract the phosphate
