文章亮点

  • (1) 超声波–强碱组合方法可减弱捕收剂在白钨矿表面的吸附并强化解吸。
  • (2) 超声波–强碱组合方法可解吸白钨精矿表面90.48%的Pb和63.75%的BHA。
  • (3) 超声波–强碱组合方法对解吸的捕收剂Pb离子和BHA活性没有破坏作用。
  • (4) 含有捕收剂的解吸液回用到浮选中，可节约25%的捕收剂用量。
  • 浮选是通过捕收剂对目的矿物的选择性吸附使其疏水上浮进而实现矿物分离富集的方法。浮选精矿表面吸附的捕收剂通常会对后续冶金过程产生不利影响，如降低产品纯度、毒化离子交换树脂、增加废水COD值等。为消除上述影响，通常需在冶金作业前将精矿表面的捕收剂脱除，但造成药剂浪费、冶金成本增加。本文提出在选矿厂将精矿矿浆进行简单处理使捕收剂从精矿表面解吸，并将含有捕收剂的解吸液直接返回用于浮选的新思路，既能减少浮选药剂成本，又能降低后续对于冶金的不利影响。硝酸铅-苯甲羟肟酸(Pb-BHA)配体是白钨矿浮选中常用的捕收剂。本文研究了不同物理方法(搅拌或超声)和化学方法(强酸或强碱)对白钨矿精矿表面Pb-BHA捕收剂解吸行为的影响。单矿物解吸试验表明，在矿浆pH值为13、超声处理15分钟的条件下，白钨精矿表面捕收剂的解吸效果最佳，Pb和BHA解吸率分别为90.48%和63.75%。实际矿浮选试验表明，采用强碱-超声组合方法解吸白钨精矿表面捕收剂并将解吸液用于浮选，可节省选矿厂25%的Pb离子和30%的BHA用量。机理研究表明，强碱环境破坏了Pb离子与BHA之间的化学键，超声波的空化效应有效降低了Pb-BHA捕收剂与白钨矿表面的作用强度，利于捕收剂的解吸脱附，但不会破坏捕收剂的活性。可见，超声–强碱组合方法可实现浮选精矿表面捕收剂的有效解吸，为冶炼厂提供“干净”的白钨精矿，捕收剂回用可有效降低选矿厂的捕收剂使用成本。

    Efficient desorption and reuse of collector from the flotation concentrate: A case study of scheelite

    + Author Affiliations
      Abstract
    • Flotation is the most common method to obtain concentrate through the selective adsorption of collectors on target minerals to make them hydrophobic and floatable. In the hydrometallurgy of concentrate, collectors adsorbed on concentrate can damage ion-exchange resin and increase the chemical oxygen demand (COD) value of wastewater. In this work, we proposed a new scheme, i.e., desorbing the collectors from concentrate in ore dressing plant and reusing them in flotation flowsheet. Lead nitrate and benzohydroxamic acid (Pb-BHA) complex is a common collector in scheelite flotation. In this study, different physical (stirring or ultrasonic waves) and chemical (strong acid or alkali environment) methods for facilitating the desorption of Pb-BHA collector from scheelite concentrate were explored. Single-mineral desorption tests showed that under the condition of pulp pH 13 and ultrasonic treatment for 15 min, the highest desorption rates of Pb and BHA from the scheelite concentrate were 90.48% and 63.75%, respectively. Run-of-mine ore flotation tests revealed that the reuse of desorbed Pb and BHA reduced the collector dosage by 30% for BHA and 25% for Pb. The strong alkali environment broke the chemical bonds between Pb and BHA. The cavitation effect of ultrasonic waves effectively reduced the interaction intensity between Pb-BHA collector and scheelite surfaces. This method combining ultrasonic waves and strong alkali environment can effectively desorb the collectors from concentrate and provide “clean” scheelite concentrate for metallurgic plants; the reuse of desorbed collector in flotation flowsheet can reduce reagent cost for ore dressing plants.
