摘要(Abstract):

蛇纹石、滑石和绿泥石是典型的层状镁硅酸盐矿物,三者通常呈组合的方式赋存于硫化矿中。硫化矿浮选过程中,蛇纹石、滑石和绿泥石易进入硫化精矿且恶化浮选环境,造成精矿品质不高、回收率较低等问题,与硫化矿往往难以实现高效分离。目前,针对此类硅酸盐类脉石矿物,如何采用适宜的选矿药剂进行高效选择性抑制,仍然是浮选领域研究的热点与难点。分析了蛇纹石、滑石和绿泥石晶体化学特征与浮游性能的关系,蛇纹石表面荷正电,可用阴离子捕收剂浮选;滑石是分子晶体,天然可浮性较好,常用脂肪酸类和胺类捕收剂浮选;绿泥石天然可浮性仅次于滑石,可用阴阳离子捕收剂浮选。同时综述了无机、有机、新型及组合四个类别抑制剂的研究现状,无机抑制剂已成功应用于工业生产中,新型有机抑制剂的合成和应用是未来研究的重点和热点,组合抑制剂协同抑制机理研究尚待加强。还阐述了各类药剂的作用原理和应用,为新型、高效、绿色抑制剂的筛选与合成指明了方向,为抑制剂的组合使用提供了参考,为硫化矿的高效浮选回收提供了技术支撑。
