In mineral processing operations, besides target minerals, slurries often contain various metal ions, including common ones with different valence states such as Pb2+, Cu2+, Fe2+, and Fe3+. These ions originate from multiple sources during the flotation process, dissolution of co-occurring minerals crushing grinding, addition reagents, water. Investigators have long recognized that significantly affect behavior. Due to physical chemical interactions, some in slurry will interact mineral. If these form hydrophobic substances on surface or increase active sites between collectors sulfide agent, they a positive impact process. Conversely, if produce hydrophilic deplete added sulfides, negatively enrichment. Meanwhile, can regulate electrostatic repulsion reagents surfaces system, which has certain results. This study provides comprehensive overview flotation, explores their adsorption characteristics surfaces, examines It theoretical basis for improving processes presence ions.
