The quartz and silicate gangue minerals found in the fluorite ore in the alkaline medium, which is usually the fluorite flotation medium, are highly negative in surface charge [4–6]. Therefore, used anionic collectors cannot be physically adsorbed on the surface of fluorite particles, which helps to arrest this mineral [ 7 10 ].Minerals Free FullText Selective Separation ,Fluorite, barite and calcite are important industry minerals. However, they often coexist, presenting difficulty in selectively separating them due to their similar surface properties. In this study, valonea extract and sodium
