| 摘 要： | 在对某碳酸盐型高泥萤石矿的选矿试验中,采用了新型抑制剂和新的流程:在常规条件下通过一次粗选脱除大部分矿泥和部分方解石,然后再进行方解石和萤石的浮选分离,经过一段磨矿—两粗—五精—两扫的选别流程获得了合格的精矿;其中精矿中CaF2品位95.37%,CaCO3品位3.06%,CaF2回收率76.61%,最终尾矿CaF2品位12.36%.研究表明,改性水玻璃NSOH中对方解石起主要抑制作用的为胶态硅酸和SiO2(OH)22-离子,并得出各组分对矿物抑制能力的顺序:SiO2(OH)22->Si(OH)4>HSiO3-.其抑制作用主要是由于不同矿物对胶态硅酸和SiO2(OH)22-离子的吸附能力不同,其...

| Abstract: | A new type depressant was introduced in the flotation test of a certain fluorite ore containing carbonates and lots of sludge.Part of calcite and most of fluorite were separated from sludge by bulk flotation under conventional conditions through a rougher as first step,then the fluorite and calcite were separated by another rougher.A process of several steps in cleaning flotation was needed to obtain desirable fluorite concentrates,including the grinding once,roughing twice,clean-out five times and scavengi... |
