Purification of gypsum
Although the Central PRAYON Process can produce merchant grade calcium sulfate directly from the filter, Prayon also offers clean-up downstream from existing dihydrate plants.
This process involves :
- classification of the gypsum by removing the fine and coarse particles;
- washing the gypsum to remove the soluble components (mainly residual phosphate, fluorine, and sodium);
- filtering and drying the beneficiated dihydrate.
