Phosphogypsum is a waste by-product from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as superphosphate. The wet chemical phosphoric acid treatment process, or ‘wet process’, in which phosphate ore is digested with sulfuric acid, is widely used to produce phosphoric acid and calcium sulfate, mainly in dihydrate form (CaSO 4 · 2H 2 O):

How phosphate is mined and processed

2014-4-21 · Most phosphate reserves are from sedimentary rocks. The phosphate forms in the shallow oceans mainly due to bacterial activity, but only when several conditions are met. Their formation is pretty rare! For example, phosphates form only in warm, tropical oceans where there is a cold upwelling next to shore. There needs to be a source of phosphorus. Usually this is an abundance of dead organic matter. (There's a reason that Florida's phosphate region is also called the Bone Beds.) Bacteria feed off nutrients from the organic matter and the cold upwelling water and release the phosphorus element from the organic matter. Other bacteria help crystallize that phosphate as a mud. Finally, the right set of processes is needed to concentrate the phosphate into one layer. This can be a combination of physical processes (wave erosion) and biological processes (benthic organisms eating and then excreting phosphate pellets). It should be noted that the previous paragraph overly simplifies a complicated process

2014-4-21 · rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
