为了从含有萤石、重晶石、石英、赤铁矿和氟碳铈矿等矿物的复杂矿石中回收氟碳铈矿,对一些主要矿物的浮选回收进行了研究。对复杂矿石进行了浮选分离试验,获得了高品位的氟碳铈矿精矿(69.8—71.8％)。试验结果表明:通过添加硅酸钠或者既添加硅酸钠又添加氯化铝进行浮选以及通过添加Sulfosuccinate並将矿浆温度调解到45—50℃进行浮选,均可以从复杂矿石中有效地回收氟碳铈矿。 In order to recover bastnaesite from complex ores containing minerals such as fluorite, barite, quartz, hematite and bastnaes, flotation recovery of some major minerals was studied. The complex ore was flotation separation test, obtained a high grade bastnaesite concentrate (69.8-71.8%). The results show that the recovery from complex ores can be effectively achieved by the addition of sodium silicate or by the addition of aluminum silicate for both flotation and the addition of Sulfosuccinate and the temperature of the pulp to 45-50 ° C for flotation Bastnaesite.
