中文摘要: 甘肃某多金属矿可综合回收利用的有价元素为铜、金、银、硫,试验研究针对该矿石次生铜含量高、铜硫嵌布关系紧密、有用矿物粒径细的性质特点采用铜硫混合浮选—粗精矿再磨—铜硫分离工艺流程和新型药剂酯-11,获得了铜品位19.05%、铜回收率90.07%、金品位7.46g/t、金回收率60.43%、银品位42.00g/t、银回收率41.20%的铜精矿和硫品位41.28%,硫回收率62.22%的硫精矿,为该矿石的综合回收提供了技术依据。
Abstract:The valuable elements that can be comprehensively recycled from a polymetallic ore in Gansu province are copper, gold, silver and sulfur. According to the characteristics of high secondary copper content, close copper-sulfur intercalation and fine particle size of useful minerals, the experimental research adopts the process flow of “copper-sulfur mixed flotation-coarse concentrate regrinding –copper-sulfur separation” and the new reagent ester -11 ,which obtains not only the copper concentrate with copper grade of 19.05%, copper recovery rate of 90.07%, gold grade of 7.46g/t, gold recovery rate of 60.43%, silver grade of 42.00g/t, silver recovery rate of 41.20% ,but also the sulfur concentrate with sulfur grade of 41.28% and sulfur recovery rate of 62.22%. It provides technical basis for comprehensive recovery of the ore.
