细泥级钨矿跳汰联合选矿设备

责任编辑:金工机械 发表时间:2016-05-28 09:13

  钨是一种宝贵的稀有金属,被称为“工业的牙齿”。我国钨资源十分丰富,是公认的钨资源大国,储量占世界总储量的60%左右,居世界第一。长期以来,我国开发利用的钨矿产资源主要是黑钨矿,但近几年的统计资料表明,由于长期的超负荷开采,黑钨资源在不远的将来有可能枯竭。因此,加深对黑钨矿选矿技术的认识和理解,对合理开发和充分利用我国钨资源,保证钨资源的可持续发展具有重要的指导意义。

  粗粒级黑钨矿的选矿工艺以重选为主,其中跳汰早收、摇床精选是重选的核心。多年来,黑钨重选流程结构基本没有变化,只是一些高效节能的重选设备有所发展。跳汰选矿是在垂直变速介质流中按密度分选矿石的过程。动筛跳汰机由于跳汰室床层筛网的上下振动与水介质运动相结合,能获得比普通隔膜跳汰机更大的冲程,因而具有选别粒度粗(上限可达40mm)、处理能力大、选别效率高、耗水量小等特点,是一种粗、中粒矿石的优良重选设备。近年来,动筛跳汰机代替隔膜跳汰机在黑钨矿山中得到了广泛的应用。荡坪钨矿半山边选厂用动筛隔膜跳汰机取代原丹佛隔膜跳汰机进行粗粒和中粒黑钨矿的选别,作业回收率分别由70%和65%提高到76%和68%,节约用水3.46m³/t。大吉山钨矿选厂根据试验结果,将粗粒跳汰作业原先使用的隔膜跳汰机全部改为动筛跳汰机,使该选厂每年节约用水454万m³,节约用电341万kWh,大大降低了选矿成本。

  跳汰选矿法在粗粒黑钨矿选矿青海快3流程中居主要地位。同隔膜跳汰机相比,动筛跳汰机由于入选上限粒度大、分选精度高、耗能较少、自动化程度高等优点,受到选矿界的普遍关注。推广应用动筛跳汰机来代替隔膜跳汰机,很大程度上提高了重选厂的经济效益。

  近年来,以更合适的设备取代摇床为大家所关注。福建宁化行洛坑钨矿采用螺旋溜槽—摇床流程代替单一的摇床流程进行粗选,结果表明:螺旋溜槽—摇床流程所得精矿的品位高于单一摇床流程精矿的品位,而总回收率相近,可在很大程度上降低重选成本,提高经济效益。螺旋溜槽是一种矿砂分选重选设备,分选原理是矿浆流沿垂直的中心轴向下作螺旋运动,在重力和离心力的作用下使矿石按密度和粒度分层和分带,从而达到分离的目的。螺旋溜槽具有结构简单、单台设备占地面积小、无传动部件、处理量大、耗电耗水量相对较小等一系列优点,另外分选过程兼有分级和脱泥作用,是一种重选丢尾的好设备。其有效回收粒级下限与摇床相同,也是30μm。近年来,螺旋溜槽在很多钨矿山得到了广泛的应用。福建宁化行洛坑钨矿用螺旋溜槽对 -0.7+0.2mm粒级进行粗粒粗选,丢弃的尾矿产率达74.07%,含钨只有0.05%,丢尾效果十分显著。赣州有色冶金研究所熊新兴在对江西某贫细杂钨、钽、铌、铍矿石的实验室选矿试验中发现,螺旋溜槽的粗选指标与摇床相近,之后在选矿厂采用螺旋溜槽代替摇床进行粗选段的扩大试验,取得了较好的选矿指标,预计转化为生产后每年可节约成本约60万元。同摇床相比,螺旋溜槽本身不需动力,占用厂房面积小,节省了能耗和投资,且粗选指标与摇床相近,所以,螺旋溜槽用于钨矿重选流程中,在经济上比摇床优越。上述实例都说明应用螺旋溜槽的经济效益是十分可观的,值得推广。

  黑钨矿性脆,在采选过程中容易产生钨细泥(-0.074mm粒级)。钨细泥有原生细泥和次生细泥两种,选矿厂破碎系统碎矿和洗矿产生的细泥为原生细泥,磨矿系统磨矿产生的细泥为次生细泥。钨细泥采用重选法回收难度大,回收率低。因此,强化细粒黑钨矿的回收是提高钨选矿经济指标的关键。随着科技进步,细粒级黑钨矿处理工艺被不断改进和完善,许多选厂都采用了重、磁、浮多种选矿方法相结合的联合工艺流程,使精矿品位和回收率逐渐得到了提高。
