【摘要】：硫化铜矿石资源是最常见、最重要的铜矿资源,提高硫化铜矿石选矿技术水平对保障供给、建设绿色生态矿山都具有重要意义。为提高相关选矿工作者的选矿技术水平,推动硫化铜矿石选矿技术进步,从分选工艺、浮选药剂、选矿理论等3方面介绍了我国硫化铜矿石的选矿技术现状:(1)在分选工艺方面,快速、分步优先浮选工艺充分体现了"快收、早收"理念,可有效预防已单体解离的有用矿物的过磨,降低后续分选的难度,节约生产成本;低碱度浮选工艺可大幅度降低石灰用量,消除后续选别作业的活化过程,减少设备与管道的结垢;铜多金属矿石的经典浮选工艺成熟性好、适应性强,是目前应用最广泛的浮选工艺;对于性质独特的硫化铜及其多金属矿石,则必须根据矿石性质的特点,组合运用多种分选手段进行处理。(2)在浮选药剂方面,主要体现在对新型、高效、针对性强的捕收剂、抑制剂的研制与应用,以及传统药剂的合理组合使用方面。这些年,在这2方面所取得的重大进步,有力地推动了贫细杂难选矿石的开发,缓解了我国铜等优质有色金属精矿的供需矛盾。(3)对于硫化铜矿石选矿理论方面的研究,主要从电子结构、矿石性质、矿浆含氧量和矿浆溶液化学等方面展开,为硫化铜矿石选矿技术的进步奠定了基础。
[Abstract]:Copper sulfide ore resources are the most common and important copper ore resources. It is of great significance to improve the processing technology level of copper sulfide ores to ensure supply and build green ecological mines. In order to improve the technical level of ore dressing of related concentrators and promote the progress of mineral processing technology of copper sulfide ores, the flotation reagents are used in the separation of copper sulphide ores. This paper introduces the present situation of mineral processing technology of copper sulfide ore in China from three aspects: (1) in the separation process, the rapid and step preferential flotation technology fully embodies the concept of "quick recovery and early recovery". It can effectively prevent the grinding of useful minerals which have been dissociated by monomer, reduce the difficulty of subsequent separation, and save the production cost. The low alkalinity flotation process can greatly reduce the amount of lime, eliminate the activation process of subsequent separation operations, and reduce the scaling of equipment and pipelines. The classical flotation process of copper polymetallic ore is the most widely used flotation process because of its good maturity and strong adaptability. For copper sulphide and its polymetallic ores with unique properties, it is necessary to combine and use a variety of separation methods according to the characteristics of the ores. (2) in the flotation reagents, it is mainly reflected in the new type, high efficiency, The development and application of collector and inhibitor, and the rational combination of traditional agents. In recent years, the great progress made in these two aspects has promoted the development of poor, fine and difficult ore, and alleviated the contradiction between supply and demand of high quality non-ferrous metal concentrate such as copper in China. (3) the study on the theory of copper sulfide ore dressing. It is mainly carried out from the aspects of electronic structure, ore properties, pulp oxygen content and slurry solution chemistry, which lays a foundation for the progress of copper sulfide ore processing technology.
