【摘要】：针对复杂难分选铜锌硫化矿石利用困难的现状,概述了近几年来铜锌硫化矿分离的相关研究与进展,主要介绍了铜锌浮选分离工艺与药剂及选冶联合技术等3方面内容。研究认为:对于铜锌矿物嵌布粒度较粗、嵌布关系不很密切、铜锌矿物可浮性差异较大的铜锌硫化矿石,适合采用优先浮铜再浮锌的优先浮选流程处理。对于铜锌矿石矿物组成复杂,铜、锌氧化率较高,铜锌矿物共生关系致密,嵌布粒度极细,单体解离困难的铜锌硫化矿石,一般采用混合浮选再分离工艺流程处理,在铜锌分离前对铜锌混合精矿进行再磨往往有利于铜锌分离。研制像MBT一样对黄铜矿、闪锌矿浮选性能差异较大的新型、高效捕收剂是实现铜锌分离的重要手段。在锌矿物抑制剂研制方面,不仅要考虑浮选分离时锌矿物的抑制效果,还必须综合考虑锌矿物在后续浮选时的活化问题。对于普通物理选矿方法难以回收利用的铜锌硫化矿石,采用混浮预富集再湿法或火法冶金工艺分离、回收铜锌等有价金属的方法是解决此类资源开发利用的有效方法。
[Abstract]:In view of the present situation of complex and difficult separation of copper and zinc sulphide ores, the related research and progress in the separation of copper and zinc sulphide ores in recent years are summarized. This paper mainly introduces three aspects of copper and zinc flotation separation technology, combined technology of reagent and metallurgy, etc. It is considered that copper and zinc sulphide ores with coarser grain size, less close distribution relation and greater floatability of copper and zinc ores are studied. For the copper-zinc sulfide ores with complex mineral composition, high oxidation rate of copper and zinc, dense symbiotic relationship between copper and zinc ore, fine intercalation granularity and difficulty in monomer dissociation, the copper zinc sulfide ore is suitable for the preferential flotation process of copper and zinc floatation. The regrinding of copper and zinc mixed concentrate before the separation of copper and zinc is usually beneficial to the separation of copper and zinc, and a new type of flotation property of sphalerite, which is similar to MBT for chalcopyrite, has been developed. High efficiency collector is an important means to realize the separation of copper and zinc. In the development of zinc mineral depressants, not only the inhibition effect of zinc minerals in flotation separation should be considered. It is also necessary to consider the activation of zinc minerals in subsequent flotation. For copper and zinc sulphide ores which are difficult to be recovered by ordinary physical processing, mixed flotation preconcentration and rehydration or pyrometallurgical process are used to separate copper and zinc sulphide ores. The method of recovering valuable metals such as copper and zinc is an effective method to solve the exploitation and utilization of such resources.
