摘　　要：选矿方面,目前浮选仍是铜钴矿最主要的选矿方法,选别流程一般分为优先浮和混合浮选。对混合矿通常采用先硫后氧或磁浮联合工艺,对硫化矿则采用黄药类捕收剂选别处理即可。冶金方面,随着萃取工艺的发展和高效萃取剂的研发应用,依靠萃取技术在提纯铜钴酸浸液的优势越来越显著;火法焙烧工艺方面,随着焙烧烟气处理技术的发展应用以及低浓度SO_(2)制酸技术趋于成熟,不仅可以解决焙烧过程中烟气污染问题,还能实现原料中硫资源的高效回收利用。选冶结合、火法湿法联合的处理方案,可以充分发挥各自优势,尽可能高效经济回收多种有价金属,为综合利用刚果(金)及周边区域铜钴矿资源打下坚实的基础。In terms of beneficiation,flotation is still the main beneficiation method for copper cobalt ore,and the beneficiation process is generally divided into priority flotation and mixed flotation.For mixed ore,a combined process of sulfur followed by oxygen or magnetic levitation is usually used,while for sulfide ore,a xanthate type collector can be used for sorting treatment.In terms of metallurgy,with the development of extraction processes and the development and application of efficient extractants,the advantage of relying on extraction technology in purifying copper cobalt acid leaching solution is becoming increasingly significant;In terms of fire roasting process,with the development and application of roasting flue gas treatment technology and the maturity of low concentration SO_(2) acid production technology,it can not only solve the problem of flue gas pollution during the roasting process,but also achieve efficient recovery and utilization of sulfur resources in raw materials.The treatment plan combining selection and metallurgy,as well as the combination of fire and wet processes,can fully leverage their respective advantages and efficiently and economically recover various valuable metals,laying a solid foundation for the comprehensive utilization of copper and cobalt ore resources in the Democratic Republic of Congo and surrounding areas.
