Reverse anionic flotation of dolomitic collophanite using a mixed fatty acid collector: Adsorption behavior and mechanism Open
Collophanite in south China generally has a high MgO level, which negatively impacts wetprocess phosphoric acid production and cannot be utilized directly.A novel mixed fatty acid soap (GSWF01) was employed as a collector for dolomite.A si…
