Abstract:Pyrite is the most widely distributed pyrite in the Earth’s crust, with which arsenopyrite often occurs in close association, Their structure and surface chemical properties are similar and they are not easy to separate. Therefore, the produced pyrite concentrate often contains large amounts of arsenopyrite, which will seriously affect the quality of chemical acid-making products and pollute the environment. In view of the efficient utilization of mineral resources and environmental protection, the separation and comprehensive recycling of arsenopyrite and pyrite are of great significance. Flotation is the main process for the separation of sulfur and arsenic minerals. This article summarizes the flotation process and reagents of sulfur arsenic minerals and expounds the research status of sulfur arsenic minerals flotation in recent years, and looks forward to the future development direction of sulfur arsenic minerals flotation separation.
