To efficiently recover copper from magnetic separation tailings of an iron mine in Anhui, the occurrence states of copper, zinc, and sulfur minerals were investigated, and the key process conditions affecting copper recovery were optimized through flotation experiments. The results show that copper with a grade of 0.10% in magnetic separation tailings is mainly present in the form of chalcopyrite, zinc with a grade of 0.37% is mainly present in the form of sphalerite, and sulfur with a grade of 3.22% is mainly present in pyrite. All minerals are fine-grained disseminated. Employing a mixed flotation-preferential copper flotation process, the optimal reagent combination of condition test is determined as follows: collector PQ-5 dosage of 70 g/t; sphalerite depressant as a combination of 400 g/t sodium sulfide, 500 g/t zinc sulfate, and 400 g/t sodium sulfite; pyrite depressant PZ-1 dosage of 300 g/t. The closed-circuit test adopted a one roughing, three cleaning, and two scavenging process, ultimately obtaining a copper concentrate with a copper grade of 20.85% and a copper recovery of 81.41%. Meanwhile, the removal rates of zinc and sulfur in the copper concentrate reaches 94.12% and 96.30%, respectively, achieving effective separation of copper from other minerals. The research results can provide valuable reference for the efficient recovery of copper from the magnetic separation tailings of this iron mine.

针对安徽某铁矿磁选尾矿中铜资源的高效回收问题,研究了其中铜、锌、硫矿物的赋存状态,并通过浮选试验优化了影响铜回收的关键工艺条件。结果表明,磁选尾矿中品位0.10%的铜主要以黄铜矿形式赋存,品位0.37%的锌主要以闪锌矿形式赋存,品位3.22%的硫主要赋存于黄铁矿中,各矿物均呈细粒嵌布。采用混合浮选-优先浮铜流程,确定了条件试验的最佳药剂组合:捕收剂PQ-5用量为70 g/t;闪锌矿抑制剂为400 g/t硫化钠、500 g/t硫酸锌和400 g/t亚硫酸钠的组合;黄铁矿抑制剂PZ-1用量为300 g/t。闭路试验采用“一粗三精两扫”流程,最终获得的铜精矿铜品位为20.85%、铜回收率为81.41%,铜精矿中锌和硫的去除率分别达到94.12%和96.30%,实现了铜与其他矿物的有效分离。研究结果可为该铁矿磁选尾矿中铜的高效回收提供参考依据。

To efficiently recover copper from magnetic separation tailings of an iron mine in Anhui, the occurrence states of copper, zinc, and sulfur minerals were investigated, and the key process conditions affecting copper recovery were optimized through flotation experiments. The results show that copper with a grade of 0.10% in magnetic separation tailings is mainly present in the form of chalcopyrite, zinc with a grade of 0.37% is mainly present in the form of sphalerite, and sulfur with a grade of 3.22% is mainly present in pyrite. All minerals are fine-grained disseminated. Employing a mixed flotation-preferential copper flotation process, the optimal reagent combination of condition test is determined as follows: collector PQ-5 dosage of 70 g/t; sphalerite depressant as a combination of 400 g/t sodium sulfide, 500 g/t zinc sulfate, and 400 g/t sodium sulfite; pyrite depressant PZ-1 dosage of 300 g/t. The closed-circuit test adopted a one roughing, three cleaning, and two scavenging process, ultimately obtaining a copper concentrate with a copper grade of 20.85% and a copper recovery of 81.41%. Meanwhile, the removal rates of zinc and sulfur in the copper concentrate reaches 94.12% and 96.30%, respectively, achieving effective separation of copper from other minerals. The research results can provide valuable reference for the efficient recovery of copper from the magnetic separation tailings of this iron mine.

铜资源是有色金属资源的重要组成部分,在国民经济的各个领域发挥着不可替代的作用[1-2]。铜作为人类最早利用的金属之一,在史前时代就开始被采掘和应用,自然铜、蓝铜矿和孔雀石曾是古代人们用来炼铜的主要矿物[3-4],对早期人类文明的发展产生了深远的影响[5-6]。随着现代采选冶技术的进步,黄铜矿、辉铜矿和斑铜矿等低品位铜矿石得到广泛开发利用[5,7-8]。当前,铜不仅广泛应用于军工、电气、机械制造等传统领域,而且在新能源、新材料等战略性新兴产业中也发挥着关键作用,已成为国家经济发展和科技进步的重要支撑和保障[9-11]。
根据国际铜业研究组织(ICSG)的数据,我国是世界第一大铜消费国,2022年的精炼铜表观消费量约为1 390 万 t,占全球总消费量的54%[12],而同期国内铜金属产量仅190 万 t,虽然居世界第三位[13-14],但远不能满足国内需求。可见,铜资源的高效开发利用对保障我国经济可持续发展具有重要战略意义,然而,随着高品位易采铜矿资源的日益减少,铜矿石的平均品位逐年下降,给传统的铜矿选矿工艺带来了巨大挑战[15]。此外,大量的低品位铜矿石和尾矿因技术经济原因被废弃,不仅造成了宝贵铜资源的浪费,也引发了环境污染等问题[16]。因此,从低品位铜矿石和尾矿中回收铜等有价金属,对于缓解我国铜资源短缺的矛盾,实现铜资源的高效利用和清洁生产具有重要意义[17]。
针对这一问题,许多学者围绕铜尾矿的赋存状态分析和回收工艺优化开展了系列研究。王玲等[18]分析了某铜矿老尾矿(铜品位为0.46%)中铜的赋存状态,发现铜主要以硫化铜(42.22%)、氧化铜(26.67%)和吸附态及包裹体(31.11%)形式赋存,针对不同赋存形式的铜需采用多种方法联合回收。李天霞等[19]研究了河北某铜尾矿(含铜0.076%)的综合回收工艺,发现采用原矿浮选泡沫作为载体,可有效回收尾砂中粒度为5~10 μm的黄铜矿,且该工艺使尾砂铜回收率达到20.41%,原矿铜回收率提高至73.17%,效果明显优于常规的尾砂和原矿单独浮选。MUANDA等[20]在对螺旋分级后铜钴氧化矿尾矿的浮选研究中发现,优化浮选试剂用量可显著提升金属回收指标,在优化条件下,粗精矿中铜、钴回收率高达82.51%和72.51%,中矿品位分别达到12.52%和0.99%;经过精选,铜、钴品位进一步提升至24.54%和1.38%,回收率虽有所下降,但仍分别有69.26%和40.7%。该工艺的应用不仅能有效回收尾矿中的铜钴资源,还能显著降低尾矿的环境风险。
上述研究为铜尾矿资源高效利用提供了重要参考,但主要聚焦于常规铜矿选矿尾矿,对于铁矿磁选尾矿这种特殊含铜二次资源关注不足。这种尾矿中铜矿物粒度更细,且常与黄铁矿等其他矿物共生连生,给选别回收带来更大挑战,亟需开展针对性研究。本文以安徽某铁矿磁选尾矿为对象,在系统研究铜矿物赋存状态的基础上,通过浮选试验优化,探讨影响铜回收的关键因素,旨在优化磁选尾矿铜回收工艺,开发具有推广价值的铜回收新技术。拟突破铜矿物超细粒级、铜锌矿难分离等技术瓶颈,获得兼顾铜回收率和铜精矿品位的浮选新工艺。新工艺不仅有望显著提高该矿铜资源利用效率、创造经济效益和社会效益,也可为类似矿山开发利用磁选尾矿提供借鉴,具有重要的理论意义和实践价值。
采用化学多元素分析的方法对某磁选尾矿的成分进行了分析,结果见表1。由表1可知,矿石中的有价元素为Cu、Zn和S,含量分别为0.10%、0.37%和3.22%,虽然铜和锌含量较低,但从资源综合利用的角度来看,回收铜和锌仍具有一定的经济价值和环境效益。此外,矿石中硫含量相对较高,推测可能与黄铁矿等硫化矿物的存在有关。
从脉石组分来看,SiO2是最主要的脉石矿物,含量高达45.17%,其次是CaO、MgO和Al2O3等,含量分别为12.52%、8.36%和7.40%。这些脉石成分的存在会影响矿石的选矿性能,需要在后续选矿试验中予以考虑。
综合化学分析结果,确定本研究的目标元素为Cu、Zn和S。由于三者的含量和赋存状态不同,在选择回收方法时需要分别考虑。本文将重点研究Cu的分离回收工艺,通过对铜矿物赋存状态的详细分析和浮选条件的系统优化,寻求一种高效、经济、环保的铜回收新工艺。同时,Zn和S的综合回收也将作为后续研究的重要内容,以期最大限度资源化利用该磁选尾矿中的有价元素。
采用MLA对该铁矿磁选尾矿中金属矿物的含量进行了测定,结果见表2。
由表2可知,尾矿中金属矿物总含量约占8%,主要金属矿物为黄铁矿,含量为5.22%,这是造成尾矿中硫含量较高的主要原因。其次是赤铁矿和磁铁矿,含量分别为1.19%和1.28%,说明该磁选尾矿中仍残留有一定量的铁矿物。此外,尾矿中还含有少量的铜、锌、铅矿物,如黄铜矿、闪锌矿和方铅矿等,含量分别为0.29%、0.56%和0.05%。这与化学分析结果基本吻合,进一步证实了尾矿中铜、锌等有价金属的存在。尾矿中毒砂和磁黄铁矿的含量极低,可忽略不计。
金属矿物成分研究结果表明,磁选尾矿中铜的主要赋存矿物为黄铜矿,属硫化物矿物,与之共生的还有黄铁矿和少量闪锌矿等其他硫化物,以及赤铁矿等铁的氧化物矿物。这些矿物在常规磁选工艺中难以有效分离和富集,导致铜大量流失到尾矿中。为进一步了解影响铜矿物选别性能的关键因素,重点分析了黄铜矿的嵌布特征和粒度分布。通过光学显微镜观察发现,黄铜矿多呈他形-半自形晶体产出,粒度主要集中在0.01~0.10 mm之间,与黄铁矿等其他硫化物呈细粒状相互交代,嵌布于脉石矿物中(见图1)。这种复杂的共生嵌布关系和细小的晶体粒度,使得铜矿物难以通过常规粗磨工艺实现有效解离和分离。因此,在铜矿物的选别过程中,需要着重考虑磨矿细度对精矿铜品位和回收率等选别指标的影响。
在含有黄铜矿、闪锌矿和黄铁矿的多金属硫化物矿石中,基于各矿物浮选特性差异,通过控制浮选条件、使用选择性抑制剂等措施,优先浮选黄铜矿、抑制闪锌矿和黄铁矿,可以简化工艺流程,有效实现铜、锌等有价金属的分离和富集,获得较好的选矿指标和经济效益[21-22]。本研究的磁选尾矿中有价成分含量较低,如果直接采用优先浮选铜矿物的工艺路线,可能难以获得理想的经济效益。因此,综合考虑经济效益和工艺可行性,决定先通过混合浮选的方式,将铜、锌、硫的矿物集中富集到混合精矿中,再以混合精矿为原料,进行铜、锌、硫的分离。本试验采用的选矿原则流程如图2所示。
在进行铜的浮选试验之前,为了获得合适的原料,本研究首先开展了混合浮选条件试验。通过系统探索和优化,确定了最佳的试剂组合和用量:石灰用量为3 000 g/t,捕收剂PQ-5用量为150 g/t,所得混合浮选试验结果见表3。
从表3可以看出,磁选尾矿混合浮选试验取得了良好的技术指标,混合精矿的铜、锌、硫品位和回收率都有显著提高,尤其是铜和硫的富集效果十分理想,铜的回收率达到91.24%,硫的回收率达到95.76%,为后续通过进一步浮选获取高品位铜精矿奠定了良好基础。
在进行铜的浮选条件试验时,研究了磨矿粒度、捕收剂种类及用量、抑制剂用量等对浮选指标的影响,具体的浮选条件试验流程如图3所示。
原料性质研究结果表明,黄铜矿嵌布粒度细微,磨矿粒度可能会对浮选结果产生显著影响。为确定最佳磨矿时间,将浮选所得混合精矿烘干后,称取50 g物料,在磨矿料浆质量浓度为60%的条件下进行不同时间的磨矿试验,测定相应的−74 μm颗粒含量,并绘制磨矿时间与粒度的关系曲线(见图4)。
由图4可知,随着磨矿时间的延长,−74 μm级别颗粒含量逐步升高。当磨矿时间从1 min增至5 min时,−74 μm含量从40.07%大幅升至89.3%,表明矿石已得到充分粉碎。继续延长磨矿时间至7 min和9 min时,−74 μm含量增幅明显减缓,分别为90.55%和91.45%,表明粉碎效果已接近极限。综合考虑矿石的粉碎程度和能耗,5~7 min是较优的磨矿时间。此时间内,矿石充分粉碎,大部分颗粒达到浮选所需−74 μm的粒径。
按照对应磨矿时间下的粒度,以图3所示流程进行浮选试验,固定条件为调整剂石灰用量2 000 g/t、闪锌矿组合抑制剂用量硫化钠400 g/t+硫酸锌500 g/t+亚硫酸钠400 g/t、黄铁矿抑制剂PZ-1用量300 g/t、捕收剂PQ-5用量30 g/t、起泡剂2#油用量20 g/t,试验结果见表4。
由表4可知,磨矿细度对铜的浮选效果有显著影响,随着−74 μm粒级含量的增加,精矿铜品位呈上升趋势,回收率呈下降趋势。综合考虑,选择−74 μm粒级含量89.30%(磨矿时间5 min)作为最佳磨矿粒度,在试验所用药剂组合的条件下,铜精矿品位为16.26%,铜回收率为61.17%。
现场生产中采用的捕收剂为608,为了提高铜的回收率,试验时拟采用两种新药剂PQ-5和PQ-6作为对比。在磨矿细度−74 μm含量89.3%、石灰用量2 000 g/t、闪锌矿组合抑制剂用量硫化钠400 g/t+硫酸锌500 g/t+亚硫酸钠400 g/t、PZ−1用量300 g/t、2#油用量20 g/t的固定试验条件下,分别考察了不同捕收剂种类(用量均固定为30 g/t)对浮选指标的影响,试验结果如图5所示。
由图5可知,在相同条件下,新型捕收剂PQ-5和PQ-6较现有的608捕收剂具有明显优势,能够同时提高精矿铜品位和铜回收率。综合考虑浮选指标,PQ-5表现最优,精矿铜品位达到16.26%,较使用捕收剂608时提高了近3个百分点,精矿铜回收率高达61.17%,较608提升了近30个百分点。因此,PQ-5是一种值得推广应用的优选捕收剂,后续试验均选用PQ-5作为捕收剂。
固定试验条件不变,考察捕收剂PQ-5的用量对铜浮选指标的影响,结果如图6所示。
由图6可以看出,随着捕收剂PQ-5用量的逐渐增大,粗精矿中铜品位呈现下降趋势,而铜回收率则缓慢上升。因为是粗选,综合考虑,选定捕收剂PQ-5用量为70 g/t,此时,铜精矿中铜的品位和回收率分别为15.37%和65.95%,既能够实现较高的铜回收率,又能够使精矿中铜品位保持在相对较优的水平。
为抑制闪锌矿,试验采用硫化钠和硫酸锌在闪锌矿表面形成疏水膜,同时联合亚硫酸钠进行协同抑制。而对于黄铁矿的抑制,则使用硫抑制剂PZ-1。
固定试验条件为石灰用量2 000 g/t、PQ-5用量70 g/t和2#油用量20 g/t,分别考察了闪锌矿抑制剂用量和黄铁矿抑制剂用量对铜浮选效果的影响,结果分别如图7和图8所示。
由图7可以看出,当不加入闪锌矿抑制剂时,铜精矿品位和回收率较低。这是因为闪锌矿易于上浮混入铜精矿,且包裹铜矿物影响其回收。当加入适量抑制剂后,闪锌矿被有效抑制,铜精矿品位和回收率显著提高。但过量的抑制剂会过度抑制闪锌矿和铜矿物,导致品位和回收率再次下降。综合考虑铜精矿品位和回收率的平衡,选择闪锌矿组合抑制剂最佳用量为硫化钠400 g/t、硫酸锌500 g/t和亚硫酸钠400 g/t。在该条件下,可有效抑制闪锌矿提高铜精矿品位,同时防止过度抑制铜矿物,维持较高铜回收率,实现铜浮选分离效果的最优化。
由图8可知,PZ-1用量对铜浮选指标影响显著。低用量(200 g/t)时,抑制黄铁矿效果差,虽然精矿铜品位较高(20.58%),但铜矿物损失大,回收率低(50.18%)。适宜用量(300 g/t)时,黄铁矿得到有效抑制,尽管铜回收率达到最佳(65.59%),但品位有所下降(15.37%)。过高用量(400~600 g/t)时,PZ-1过度抑制铜矿物,导致大量铜矿物流失,精矿品位和回收率急剧下降,600 g/t时回收率降至最低,品位略有回升,可能是少量难浮的高品位铜矿物上浮所致。
在上述开路条件试验的基础上,进行了铜矿物浮选的全流程闭路试验。经过初步探索,以磁选尾矿浮选的混合精矿为原料,确定采用“一粗三精两扫”的闭路试验流程。具体试验流程及药剂制度详见图9,最终试验结果详见表5。
由图9、表5可以看出,该全流程闭路浮选试验采用“一粗三精两扫”流程,在浮选所得精矿中获得了较高的铜回收率(81.41%)和铜品位(20.85%),实现了铜与其他矿物的有效分离,为后续铜冶炼创造了有利条件。同时,锌和硫在选铜尾矿中得到有效富集(锌回收率为94.12%,硫回收率为96.30%),为锌和硫的进一步综合回收利用提供了可能。
本研究以安徽某铁矿磁选尾矿为研究对象,通过矿石性质分析和浮选工艺试验,获得了磁选尾矿铜回收的关键工艺条件,取得了较为理想的分离指标。主要结论如下。
(1)磁选尾矿中有价元素铜、锌、硫品位分别为0.10%、0.37%和3.22%,其中铜主要以细粒黄铜矿形式赋存,锌主要以闪锌矿形式赋存,硫主要来源于黄铁矿。各种有价矿物均呈细粒嵌布,需细磨至−74 μm含量89.30%以上才能实现有效解离。
(2)采用混合浮选-优先浮铜流程,优选捕收剂为PQ-5(用量为70 g/t),闪锌矿抑制剂为硫化钠(400 g/t)、硫酸锌(500 g/t)和亚硫酸钠(400 g/t)的组合,黄铁矿抑制剂PZ-1用量为300 g/t,可获得较优的铜浮选指标。
(3)全流程闭路试验采用“一粗三精两扫”流程,在获得铜品位为20.85%、铜回收率为81.41%铜精矿的同时,使锌和硫的去除率分别达到94.12%和96.30%,实现了铜与锌、硫的有效分离,为该类型尾矿资源的综合利用提供了可行的工艺路线。
(4)本研究获得的磁选尾矿铜回收工艺,可为类似矿山开发利用提供借鉴,但仍需扩大试验规模,检验其工业应用可行性。此外,磁选尾矿中锌和硫等的综合回收也需深入研究。
