摘　　要：为更深刻探讨伴生萤石资源利用率极低的原因,针对萤石被抑制后再活化浮选的可浮性变化,进行了捕收剂、抑制剂和活化剂的单矿物浮选行为研究,通过Zeta电位分析和红外光谱分析,初步解释了被抑制后的萤石即使再活化、浮选表面活性也难以恢复、可浮性也随之变差的现象。初步证明了[SiO(OH)_3^-]、[SiO_2(OH)_2^(2-)]是影响萤石活化浮选的主要因素,同时考查了新型萤石特效活化剂ZC-1对萤石的活化性能。In view of the extremely low utilization rate of associated fluorite resources, directed at the change of float- ability of fluorite, which is activated after inhibited flotation, the collector, inhibitors and activator tests of single min- eral flotation behavior research were carried out. The Zeta potential analysis and infrared spectrum analysis were utilized to explain the problem of it. This research proved that, [ SiO（OH）3- ] and[ SiO2（OH） 22- ] can prevent the activation of fluorite. At the same time, this paper investigates the effect of activator ZC-1 on the performance of fourite.
