Froth flotation is considered as the most effective method for the beneficiation of fluorite (Foucaud et al., 2018a, Zhang et al., 2018). For fluorite-quartz or fluorite-sulfides type mineral deposits, the flotation separation of fluorite from associated minerals is relatively easily achieved by using fatty acids or xanthates as collectors.Web
