How phosphate is mined and processed

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.

Phosphogypsum - an overview ScienceDirect Topics

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):

Phosphate Fertilizer Plants - IFC

Phosphate fertilizers are produced by adding acid to ground or pulverized phosphate rock. If sulfuric acid is used, single or normal, phosphate (SSP) is produced, with a phosphorus content of 16–21% as phosphorous pentoxide (P 2 O 5). If phos-phoric acid is used to acidulate the phosphate rock, triple phosphate (TSP) is the result. TSP has
