摘　　要：在滑石矿中,脉石矿物透闪石会对滑石的浮选效果产生影响。进行了滑石和透闪石纯矿物浮选试验,研究十二烷基苯磺酸钠体系中不同抑制剂对滑石矿物可浮性的影响。结果表明:以十二烷基苯磺酸钠为捕收剂,在碱性条件下,六偏磷酸钠和植酸抑制透闪石的浮选,但对滑石浮选抑制作用不明显;而羧甲基纤维素钠对滑石和透闪石的浮选有很强的抑制作用。当十二烷基苯磺酸钠用量为160 mg/L,植酸用量为60 mg/L,p H值为8.6时,滑石和透闪石的回收率分别为80%和12%,可有效实现两种纯矿物的分离。During flotation process, tremolite has effect on talc. This article has carried on the talc and tremolite mineral flotation test, studied the twelve acting benzene sulfonic acid sodium system under the influence of different inhibitors on pure mineral flotability. The results showed that, with sodium dodecyl benzene sulfonate as collector, sodium hexameta phosphate and phytic acid inhibited the flotation of tremolite in alkaline condition, but the effect on flotation of talc was not obvious, while sodium carboxymethyl cellulose had a strong inhibition on the flotation of the two kinds of minerals. When the dosage of sodium alkylbenzene sulfonate is 60 mg/L, phytic acid dosage is 60 mg/L, p H value is 8.6, the recovery rate of talc and tremolite is 80% and 12% respectively, which can effectively seperate the two kinds of pure minerals.
