Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.This occurs through washing, .
Phosphate rock of 70 to 75% BPL, or as high as is reasonably obtainable, is finely ground in a ball mill and then mixed with cooled recycled phosphoric acid-gypsum slurry in a digestion tank (Figs. 10.3 and 10.4).At this stage the only reaction which occurs is between acid and any carbonates present in the rock, and between phosphates and low concentrations of sulfuric acid which may be ...
Apr 23, 2020· Rock phosphate, or phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize.

Phosphate rock (PR) is natural mineral deposits belongs to the species of apatite family. Apatite is a primary phosphate mineral that can differ significantly in physical, chemical, and crystallographic properties (Ahialey et al., 2014; Liu et al., 2017). Mostly PR deposits include variety of carbonate-
The source of fluorides is phosphate rock, which contains from 3.5% to 4.0% (w/w) fluorine. The fluorine is generally precipitated out with gypsum, leached out with phosphoric acid product, or vaporized in the reactor or evaporator. The reactor where phosphate rock is contacted with sulfuric acid is the primary source of emissions.
The washing treatment is the first processing of the phosphate in the mine before transport occurs. It contributes to increasing the mine's production capacity through the use of new enrichment techniques developed by OCP. For the sake of environment the El Halassa wash plant incorporates a sludge and a wastewater pond.
