我室曾采用湖南省吉首栲胶厂生产的油茶壳栲胺作为重晶石的抑制剂浮选萤石,收到良好效果,可以得到含caF_295%以上的合格萤石精矿。将原矿100克磨至55%-200目,用混合浮选法选出铅、锌(粗精矿),铅锌浮选后的尾矿再抑制重晶石浮选萤石。粗选萤石泡沫经过六次精选后得最终精矿。试验结果: 1.重晶石与萤石的可浮性相近,单用水玻璃作抑制剂时,萤石重晶石同时上浮,不能分离。用栲胶抑制重晶石效果良好,可以得到合格萤石精矿。 My room had been used in Hunan Jishou Tang plastic factory production of Camellia Chaba amine barite as a barite inhibitor fluorite, received good results, can be obtained with caF_295% qualified fluorite concentrate. 100 grams of ore ground to 55% -200 mesh, the mixed flotation method selected lead, zinc (crude concentrate), lead and zinc flotation tailings and then inhibit barite flotation fluorite. Crude selection of fluorite foam concentrate after the final six were selected concentrate. Test results: 1. Barite and fluorite flotability similar, single water glass as inhibitor, fluorite barite at the same time floating, can not be separated. Barium sulfate inhibition barite good effect, you can get qualified fluorite concentrate.
