摘　　要：针对某矿山选厂选铜指标差,以生产过程存在的各种问题为导向,开展了从原矿工艺矿物学分析、工业用水治理、选矿设备与工艺流程改造等一系列的科学研究,找出生产指标低的原因并进行了解决,其中浮选机-浮选柱联合技术和工业水质治理是解决生产问题的关键。新技术投入生产应用后,选铜品位提高了0.55个百分点,回收率提高了12个百分点,选矿技术全面迈上新台阶,技术改造效果显著。本次技术改造的成功经验可为公司近期新建的7000t/d铜硫新选厂提供直接的选矿技术支持,也可为国内硫化矿选矿厂的科技攻关方向提供参考。In order to improve the copper beneficiation performance in a copper mine in Guangdong,methods from the ore process mineralogical analysis,industrial water treatment,mineral processing equipment and transformation were carried out.Problems were identified and resolved,in all the methods,the flotation machine-flotation column combined technology and industrial water quality control is the key to solve the production problem.After the new technologies were put into production,copper concentrate grade rate increased by 0.55%and recovery rate increased by 12%and benefits significantly increased.The successful experience of this technical transformation can provide direct technical support for the new 7000t/d copper-sulfur concentrator,and also provide reference for the scientific and technological research direction of domestic sulphide ore concentrator.
