However,it is difficult to recover by hand dressing.
针对粗选段矿石洗矿分级后,矿石在皮带运输过程中易发生二次碰撞,所产生的细粒矿品位高,手选难以回收,采取在同一皮带上增设正、反两种手选,预先丢废,减小矿层厚度,安装脱细筛等改进措施,使生产指标得到了改善,钨的回收率提高了1。

手选
hand sorting
Sh0UXU0n手选(hand sorting)根据有用矿石和废石(围岩)在颜色和光泽上的差异用手工拣选的分选方法。依据拣选对象的不同可分为正手选和反手选。拣出废石的称为正手选,拣出有用矿石的称为反手选。手选的原则是选出的废石品位(有用成分含量)应低于选矿厂的尾矿品位。手选一般要在矿石经洗矿和分级后进行。分级的上限拉度为150一20omm,下限粒度为18~Zomm。手选作业是在手选皮带机或手选平台上进行。手选皮带机的运行速度为0.2一0.4m/s,皮带宽度不大于1200mm。手选平台面积按工作人数确定,四个人工作的手选平台面积约为3.2m2。中国钨矿山对矿石进行预选主要采用手选。一般将原矿分为三级或四级进行手选。手选废石率约为50%,可将选后的矿石品位提高到原矿品位的一倍以上。手选作业回收率可达96%以上。手选的特点是简单易行,投资少,但劳动强度大,生产工效低。随着现代技术的不断进步,手选作业将逐渐为机械拣选和重介质选矿所取代。 (卢继美张洪恩)
