how to filter disc carbon dioxide in phosphate beneficiation p

  • Optimization of thermal beneficiation of a low grade

    In acidulation the carbon dioxide produced during acidulation causes more foaming and results in production of smaller size gypsum crystals that may blind the downstream phosphogypsum filters and a low quality phosphoric acid is produced (Lodha et al. 1984). The carbon dioxide also contaminates the equipment and pollutes the atmosphere.
