Magnesite is an important source of MgO, which is often used as a refractory. Magnesite is usually associated with quartz, so the foam flotation separation and purification of magnesite is still a difficult subject. Herein a novel Gemini anionic surfactant sodium bis(dodecylethoxy) disulfate (SBDD)...
