The relationship between anion distribution in process

Abstract It is inevitable for the presence of dissolved ions, especially inorganic cations or anions, in the process water of an industrial flotation system. They could alter the chemistry of a flotation system and interfere with the interaction between minerals and reagents. The purpose of this study was to identify the relationship between anion distribution in the process water and the
