锡石多金属矿跳汰选款设备

责任编辑:金工机械 发表时间:2016-05-28 08:39

  跳汰选矿是最重要的重选方法之一,通过重选进行预先抛尾时,采用跳汰机可有效提高抛废率和降低金属损失率,而人工床层对跳汰机的分选效果有重要影响。一般认为,跳汰机人工床层具有以下作用:

  为了满足生产上的需要,跳汰机人工床层材料应具有合适的密度、粒度、颗粒形状和较好的耐磨性及抗冲击性。广西某选矿厂处理锡多金属硫化矿石,主工艺流程中采用跳汰机进行预先粗粒抛废。以往跳汰机以天然硫化矿石作为人工床石,在使用过程中存在密度偏小、粒度不均匀、形状极不规则、耐磨性差、耗损大、易堵筛网等诸多不足,使跳汰分选效果受到影响,造成抛废率低,跳汰精矿混有大量脉石,影响后续作业选别效率。为此,三久重工机械根据选矿厂实际情况特别定制了铁基复合材料新型跳汰床石,并进行了实验室和工业性应用试验,结果显示,采用新型跳汰床石与采用天然硫化矿床石相比,跳汰作业抛废率大幅提高,锡、铅、锌损失率大幅下降,精矿富集比也有所提高,表明新研制出的铁基复合材料小球作为跳汰人造床石完全可行,且具有较明显的性能优势。
