湖南某萤石矿含CaF2为10．65％，属于低贫萤石矿，试验采用预先脱硫-浮选萤石工艺，在弱酸性介质精选的工艺制度下，通过一次粗选八次精选二次扫选，获得了CaF2品位为97．80％、回收率为49．25％的萤石精矿产品，萤石浮选尾矿采用重选综合回收白钨矿，重选白钨精矿含WO367．97％，回收率53．42％。
湖南某螢石礦含CaF2為10．65％，屬于低貧螢石礦，試驗採用預先脫硫-浮選螢石工藝，在弱痠性介質精選的工藝製度下，通過一次粗選八次精選二次掃選，穫得瞭CaF2品位為97．80％、迴收率為49．25％的螢石精礦產品，螢石浮選尾礦採用重選綜閤迴收白鎢礦，重選白鎢精礦含WO367．97％，迴收率53．42％。
호남모형석광함CaF2위10．65％，속우저빈형석광，시험채용예선탈류-부선형석공예，재약산성개질정선적공예제도하，통과일차조선팔차정선이차소선，획득료CaF2품위위97．80％、회수솔위49．25％적형석정광산품，형석부선미광채용중선종합회수백오광，중선백오정광함WO367．97％，회수솔53．42％。
A pre-desulfurization-fluorite flotation process was adopted in this research to treat a low grade fluorite ore from Hu'nan with a CaF2 grade of 10.65%.Then a fluorite concentrate contai-ning 97.80%CaF2 , with a recovery of 49.25%was obtained by one roughing , eight cleanings and two scavengings.Finally, scheelite was recovered from the fluorite flotation tailings with gravity separation, outputting a scheelite concentrate containing WO 3 67.97%with a recovery of 53.42%.
