  根据该钨锡矿的工艺矿物学特性,结合国内外钨锡选矿研究相关内容,一般钨锡矿粗选采用重选,精选根据分选不同的矿物种类及性质,分别采用磁选、电选、重选或浮选工艺等。钨锡矿最主要的粗选工艺是重选,由于钨锡矿性脆,在破碎和磨矿过程中,它们易于过粉碎和过磨,易于泥化并进入矿泥中,在下一步选别作业中难以回收,大大降低钨、锡的选矿回收率青海快3。选择合适的重选入选粒度、丢尾粒度,是确保整个方案合理实施的前提。入选粒度过粗,有用矿物未单体解离,重选回收效果差,入选粒度过细,有用矿物易过粉碎,重选可回收部分的量减少,细粒有用矿物流失,严重影响重选的回收效果。

  从试验结果可以看出,-10mm+5mm粒级原矿经跳汰选矿青海快3,精矿虽然有一定的富集作用,回收率也比较高,但精矿品位较低,不利于下一步精选作业的选别;而-5mm+3mm和-3mm+2mm粒级原矿则可得到较高品位的精矿和回收率。这表明,原矿从-5mm开始才能得出一定量的较高品位精矿。从尾矿品位结果可以看出,原矿从-1mm+0.5mm级别才能开始丢弃部分较低钨锡品位的尾矿。因此,确定本钨锡矿的入选粒度为5mm、最终丢尾粒度为1mm。

  在确定了合适的入选磨矿粒度和抛尾粒度的条件下,进行了粗选流程试验,为防止或减少钨锡过粉碎现象的发生,确定了阶段破磨、阶段选别,多级跳汰、多级摇床、再磨再选、细泥单独处理的工艺流程。原矿破碎至-5mm分级为-5mm+1mm和-1mm+0mm两个级别,其中前一个级别采用跳汰首先回收部分已解离的钨锡粗精矿,选别尾矿磨碎至-1mm,与尾矿-1mm+0mm粒级合并后进行抛尾与再回收。试验采用设备为240*800梯形跳汰机、400*300离心选矿机、细砂摇床。
