The main valuable elements of a copper-molybdenum ore in Pakistan are copper, molybdenum, gold and silver, with copper content of 0.55% and molybdenum content of 0.01% in the raw ore. The contents of associated gold and silver are 0.1 g/t and1.15 g/t respectively. The content of easily mudding gangue minerals such as sericite and chlorite in the ore is high, resulting in a low grade of copper concentrate. In order to solve the above problems, a new-type inhibitor CD-B was developed to inhibit mudding gangue minerals. The process flow of “rough grinding, three-stage roughing with tailings discharge, rough concentrate regrinding and recleaning” was adopted. A copper-molybdenum mixed concentrate with a copper grade of 26.76% and a molybdenum grade of 0.451% can be obtained. The copper recovery rate is 94.49% and the molybdenum recovery rate is 77.48%. The copper-molybdenum mixed concentrate contains 2.06 g/t gold and 32.66 g/t silver, with gold recovery at 40.17% and silver recovery at 55.38%, demonstrating good beneficiation indicators. The new-type inhibitor CD-B is a small-molecule organic compound, featuring zero toxicity, zero pollution, low reagent consumption, and belongs to a high-efficiency green environmental protection reagent. Compared with the conventional reagent of sodium silicate, CD-B can significantly improve the grade of copper concentrate. The consumption of CD-B is only 1/15 of that of sodium silicate, making it convenient for procurement, storage and use.

巴基斯坦某铜钼矿主要有价元素为铜、钼、金、银,原矿含铜0.55%,含钼0.01%,伴生金、银分别为0.1 g/t和1.15 g/t。矿石中绢云母、绿泥石等易泥化脉石矿物含量较高,导致铜精矿品位不高。为解决上述问题,开发新型抑制剂CD-B抑制泥化脉石矿物,采用“粗磨—三次粗选抛尾—粗精矿再磨再选”的工艺流程,可获得铜品位为26.76%、钼品位为0.451%的铜钼混合精矿,铜回收率为94.49%,钼回收率为77.48%;铜钼混合精矿中含金2.06 g/t、含银32.66 g/t,金回收率为40.17%,银回收率为55.38%,选矿指标良好。新型抑制剂CD-B为小分子有机物,零毒性,零污染,药剂单耗低,属于高效绿色环保药剂。与常规药剂水玻璃相比,采用CD-B可大幅提高铜精矿的品位,CD-B单耗是水玻璃的1/15,便于采购、储存和使用。

巴基斯坦某铜钼矿主要有价元素为铜、钼、金、银,原矿含铜0.55%,含钼0.01%,伴生金、银分别为0.1 g/t和1.15 g/t。矿石中绢云母、绿泥石等易泥化脉石矿物含量较高,导致铜精矿品位不高。为解决上述问题,开发新型抑制剂CD-B抑制泥化脉石矿物,采用“粗磨—三次粗选抛尾—粗精矿再磨再选”的工艺流程,可获得铜品位为26.76%、钼品位为0.451%的铜钼混合精矿,铜回收率为94.49%,钼回收率为77.48%;铜钼混合精矿中含金2.06 g/t、含银32.66 g/t,金回收率为40.17%,银回收率为55.38%,选矿指标良好。新型抑制剂CD-B为小分子有机物,零毒性,零污染,药剂单耗低,属于高效绿色环保药剂。与常规药剂水玻璃相比,采用CD-B可大幅提高铜精矿的品位,CD-B单耗是水玻璃的1/15,便于采购、储存和使用。

The main valuable elements of a copper-molybdenum ore in Pakistan are copper, molybdenum, gold and silver, with copper content of 0.55% and molybdenum content of 0.01% in the raw ore. The contents of associated gold and silver are 0.1 g/t and1.15 g/t respectively. The content of easily mudding gangue minerals such as sericite and chlorite in the ore is high, resulting in a low grade of copper concentrate. In order to solve the above problems, a new-type inhibitor CD-B was developed to inhibit mudding gangue minerals. The process flow of “rough grinding, three-stage roughing with tailings discharge, rough concentrate regrinding and recleaning” was adopted. A copper-molybdenum mixed concentrate with a copper grade of 26.76% and a molybdenum grade of 0.451% can be obtained. The copper recovery rate is 94.49% and the molybdenum recovery rate is 77.48%. The copper-molybdenum mixed concentrate contains 2.06 g/t gold and 32.66 g/t silver, with gold recovery at 40.17% and silver recovery at 55.38%, demonstrating good beneficiation indicators. The new-type inhibitor CD-B is a small-molecule organic compound, featuring zero toxicity, zero pollution, low reagent consumption, and belongs to a high-efficiency green environmental protection reagent. Compared with the conventional reagent of sodium silicate, CD-B can significantly improve the grade of copper concentrate. The consumption of CD-B is only 1/15 of that of sodium silicate, making it convenient for procurement, storage and use.

铜是需求量仅次于铝的第二大有色金属,由于其优异的导电性、导热性、耐腐蚀性、延展性,在军工、电力、通信、机械等行业应用广泛[1-3]。同时,铜被认为是实现低碳未来的17种关键金属材料之一,低碳技术比传统的化石燃料技术需要消耗更多的铜,因此,铜的需求量将持续增长[4-6]。多数铜金属来源于自然界中的硫化铜矿物[7-8],在其选矿过程中,通常要考虑伴生金属的综合回收,如钼、金、银等[9-11],实现矿产资源“吃干榨净”的理念。同时,降低精矿中杂质组分的含量、降低冶炼过程中的能源消耗,是行业绿色健康发展的重要保障。因此,研究硫化铜矿高效选矿具有重要意义。
硫化铜钼矿的选矿通常采用浮选法。在浮选过程中,易泥化脉石矿物对浮选干扰较大,导致精矿品位低、含杂高。对于绢云母和绿泥石等含量较高的矿石的浮选,国内外通常采用水玻璃、六偏磷酸钠、羧甲基纤维素、腐殖酸钠、淀粉、糊精、硫酸铝、果胶[12]等抑制剂,其中常用抑制剂水玻璃、六偏磷酸钠和硫酸铝抑制能力较弱,用量较大,药剂成本高;羧甲基纤维素、腐殖酸钠、淀粉、果胶和糊精对绢云母、绿泥石的抑制能力强,但选择性差,对伴生金属钼的抑制能力也强,导致钼的回收率大幅降低。因此,研发抑制能力强、选择性好的泥化脉石矿物抑制剂是铜钼矿浮选的重点研究方向。
本文研发新型小分子有机抑制剂CD-B,在确保铜钼金属的最大化回收的前提下,提高精矿品位,降低杂质含量,以获得优异的选矿指标,为该矿石及同类型复杂难选铜钼矿资源的开发利用提供理论依据。新型抑制剂CD-B为碳水化合物,分子量小,呈白色粉末,零毒性,零污染,单耗低,属于高效绿色环保药剂。
矿石样品取自巴基斯坦西部边陲俾路支省查盖地区S2矿体。原矿含铜0.55%,含钼0.01%,伴生金、银含量分别为0.1 g/t和1.15 g/t,属于原生铜钼硫化矿。原矿中金属矿物含量低,以黄铁矿、黄铜矿为主,其次还含有少-微量赤铁矿、辉铜矿、斑铜矿、碲黝铜矿、铜蓝、辉钼矿等。原矿中铜矿物种类繁杂,主要为黄铜矿,还含有少量辉铜矿、斑铜矿、碲黝铜矿、铜蓝,结晶粒度为0.014~0.3 mm。原矿中钼矿物主要是辉钼矿,结晶粒度为0.01~0.074 mm。脉石矿物主要为石英、白云母、钠长石、正长石,其次是石英、绢云母、斜长石、金云母、绿泥石。
矿石中大于0.037 mm的铜矿物仅占64.09%,大于0.037 mm的辉钼矿仅占55.17%。铜矿物嵌布粒度细、微细粒薄片状云母和易泥化矿物绿泥石、绢云母含量高是影响精矿品位的主要因素。
原矿化学多元素分析结果见表1,铜钼矿物相分析结果分别见表2和表3,主要矿物的含量及铜钼矿物的嵌布粒度分析结果分别见表4和表5。
工艺矿物学研究表明,矿石中部分黄铜矿嵌布粒度小,以微细粒浸染状嵌布在脉石矿物中或充填在黄铁矿孔洞中的铜矿物以及沿脉石矿物解理分布的铜矿物解离难度较大,需细磨才能将黄铜矿从黄铁矿或脉石矿物中解离出来。矿石中白云母、绢云母、金云母、绿泥石等易泥化矿物或解理发育矿物含量较高、磨矿细度过细时,泥化程度高,恶化浮选矿浆环境,因此,该矿宜采用阶段磨矿、阶段选别工艺,第一阶段磨矿细度较为关键。
以石灰为黄铁矿抑制剂,Z-200和乙基黄药为铜钼捕收剂,MIBC为起泡剂,粗选时间为3 min,磨矿细度试验流程和试验结果分别如图1和图2所示。
由图2可知,随着磨矿细度的增加,粗精矿中铜钼品位先增加后降低,铜钼的回收率呈持续增加的趋势。当磨矿细度从-0.074 mm占比66%增加至72%时,铜的回收率仅提高了0.15个百分点,钼的回收率仅提高了0.93个百分点,综合考虑磨矿成本,确定第一段磨矿细度为-0.074 mm占比66%较适宜。
矿石中含有较多绢云母、金云母、绿泥石等易泥化矿物,这些矿物与铜矿物嵌布关系密切,需细磨才能实现铜矿物单体解离。但细磨会导致脉石矿物泥化严重,恶化浮选环境,导致精矿产品品位不达标[1,13-16]。
为降低泥化脉石矿物对浮选产生的影响,本文设计采用“粗磨—三次粗选抛尾”的工艺流程。因铜钼矿物的嵌布粒度较细,要获得高品质的铜精矿产品,粗精矿仍需再磨再选。为实现粗精矿再磨后有价金属与脉石矿物的高效分离,根据粗精矿中上浮脉石矿物的性质,针对性地研发了泥质脉石抑制剂CD-B,成功实现了目的矿物与泥质脉石的高效分离,矿泥抑制剂种类试验流程如图3所示,试验结果见表6。
由表6可知,水玻璃、六偏磷酸钠、CMC和CD-B对铜、钼、金和银回收率的影响较小,当抑制剂为CD-B时,粗精矿铜、钼、金和银的品位最高,因此CD-B为该矿石中泥质脉石矿物的有效抑制剂。
石灰是黄铁矿的常用抑制剂,具有价格低、抑制效果好及絮凝沉降快等特点,在各大选矿厂广泛应用[17-18],但石灰用量过大时,会导致矿浆pH过高,影响伴生金、银的回收[19-20],因此需要确定合适的石灰用量。石灰用量试验流程如图4所示,试验结果见表7。
由表7可知,随着石灰用量的增加,粗精矿中铜、金和银的品位和回收率均呈先升高后降低的趋势。石灰用量为1 500 g/t时,粗精矿中主要金属铜的品位和回收率达到最高,分别为11.52%和90.80%,伴生金、银的回收率达到最高,分别为34.01%和45.01%。与石灰用量为1 500 g/t相比,石灰用量增加至2 000 g/t时,粗精矿中铜的品位降低了1.04个百分点,铜、金和银的回收率分别降低了0.59个百分点、4.41个百分点和0.94个百分点,钼的回收率变化不大。综合考虑,确定石灰用量为1 500 g/t。
在条件试验的基础上,在0.074 mm占比66 %的粗磨细度下进行三次粗选抛尾,三次粗选以石灰为黄铁矿抑制剂,采用Z-200和乙基黄药组合捕收剂,利用多种药剂协同捕收,强化对铜钼矿物的回收,确保尾矿1中有价金属损失率处于较低水平。粗精矿经过再磨达到-0.038 mm占比88%,以石灰为黄铁矿抑制剂,利用CD-B强化对泥质脉石的抑制,Z-200为捕收剂,进行“一粗三扫三精”的再磨再选闭路试验。闭路试验流程如图5所示,闭路试验结果见表8。为便于比较,将采用水玻璃为泥质脉石矿物抑制剂的闭路试验结果也列于表8中。
由表8可知,采用水玻璃为矿泥抑制剂,用量为1 500 g/t时,闭路试验所得铜钼混合精矿中铜品位仅为17.70%,钼品位为0.29%;而采用CD-B为矿泥抑制剂,用量为100 g/t时,闭路试验可获得产率为1.95%、铜品位为26.76%的铜钼混合精矿,铜回收率为94.49%,钼品位为0.451%,钼回收率为77.48%,铜钼混合精矿中金的含量为2.06 g/t,金回收率为40.17%,银的含量为32.66 g/t,银回收率为55.38%,铜钼混合精矿中铜品位远高于采用水玻璃为矿泥抑制剂时获得的精矿,且钼在混合精矿中富集比高,为后续铜钼分离试验提供条件,伴生金、银也得到了高效回收。CD-B是该矿中脉石矿物的有效抑制剂,可大幅提高铜钼精矿的品位,药剂用量仅为100 g/t,是水玻璃用量的1/15。
(1)巴基斯坦某铜钼矿含铜0.55%,含钼0.01%,伴生金、银含量分别为0.1 g/t和1.15 g/t,属于原生铜钼硫化矿。
(2)原矿中铜矿物种类繁杂,主要为黄铜矿,还含有少量辉铜矿、斑铜矿、碲黝铜矿、铜蓝。部分硫化铜矿物和硫化钼矿物嵌布粒度较细,与脉石矿物和黄铁矿的共生关系复杂。铜矿物嵌布粒度细、微细粒薄片状云母和易泥化矿物绿泥石、绢云母含量高是影响精矿品位的主要因素。
(3)根据矿石特点,设计采用“粗磨—三次粗选抛尾—粗精矿再磨再选”的工艺流程,减弱脉石细磨泥化对浮选的影响,三次粗选采用Z-200和乙基黄药组合捕收剂强化对铜钼矿物的捕收,粗精矿再磨再选采用CD-B强化对脉石矿物的抑制能力,全流程闭路试验获得产率为1.95%、铜品位为26.76%、铜回收率为94.49%、钼品位为0.451%、钼回收率为77.48%、金含量为2.06 g/t、金回收率为40.17%、银含量为32.66 g/t、银回收率为55.38%的铜钼混合精矿产品,实现了铜钼及其伴生资源的高效回收,为新建选矿厂设计提供技术依据。
(4)新型抑制剂CD-B为小分子有机物,零毒性,零污染,单耗低,属于高效绿色环保药剂。与常规药剂水玻璃相比,采用CD-B可大幅提高铜精矿的品位,且CD-B用量是水玻璃的1/15,便于采购、储存和使用。
