Treatment technique for wastewater from bauxite flotation ...

According to the bauxite flotation process, the main factors influencing flotation wastewater were fine bauxite residue, flotation reagent residue, flocculant residue, and ion accumulation in water. Flotation reagents include collectors (small-molecule organic matter, such as oleic acid and hydroxamic acid) and regulators (NaHCO 3).
