摘要
湘南某矿萤石与含炭方解石和鳞片状绢云母紧密嵌布,萤石中有微细粒的方解石包裹体,提高萤石精矿品位的难度很大.经试验研究,选用油酸T为捕收剂及组合药剂NC+TT、组合药剂NA+TH和TD药剂为调整剂,当浮选萤石给矿品位为43.95%,其中含14.03%CaCO3和13.51%SiO2时,经一次粗选九次精选,可获得萤石精矿品位为97.50%(其中含0.93%CaCO3和0.89%SiO2),回收率80.97%的选别指标.
The fluorite is closely disseminated with carbon containing calcite and scale-like sericite and in some mine of Hunan province,improving the grade of fluorite concentrate is of great difficulty due to fine Inclusions of calcite in the fluorite.The experimental study shows: by adopting high efficiency collector oleic acid T,specific adjusting reagents NC+TT combined reagent and NA+TH combined reagent as well as reagent TD,fluorite concentrate containing 97.50% CaF_2,0.93% CaCO_3 and 0.89% SiO_2 with a recove...
