针对亚克斯公司哈密铜镍矿分离浮选中铜精矿品位低、镍精矿中含铜高、药剂用量大、分离效果差等问题,结合入选矿石性质变化和生产统计数据,通过调整浮选流程、改进药剂品种和加药方式、优化部分装置等技术措施.实践表明:铜镍分离作业改为二粗二扫四精,使用果壳活性炭与改造后的加药装置,优化管线材质与使用配置后,分离浮选过程稳定,生产技术指标提升.铜精矿品位由23.72％提升至25.46％,且伴生金含量稳定在1 g/t 以上,镍精矿含铜由0.705％降至0.493％,活性炭单耗由316 g/t下降至137 g/t,石灰单耗由2 035 g/t降至1 239 g/t,新增经济效益260.9万多元,技术改造取得了显著成效.%There were some problems,such as low-grade copper concentrate,nickel concentrate containing high copper,higher reagents dosage,poor separation efficiancy,etc.,during copper nickel separation of flotation process on sulfide nickel copper ore in Xinjiang Yakesi resource development incorporated company,Hami district,Xinjiang Uygur Autonomous region.The technical measures including adjusting the flotation process,improving the variety and addition of the reagents,optimizing the active carbon's adding device,etc.were taken to improve it,according to the variation of ore properties and production statistics.Productive practice shows that separation flowsheet of copper and nickel flotation by two roughers two scavengers four cleaners,dosing device modified and active carbon of nuts shell,pipeline material and use configuration changement,etc.are key factors to achive flotation separation process stability and production technology index improvement.The grade of copper concentrate increased from 23.72％ to 25.46％,the associated gold content more than 1 g/t,and copper nickel concentrate is down to from 0.705％ to 0.493％.Meanwhile,activated carbon consumption decreased from 316 g/t to 137 g/t,the lime consumption from 2 035 g/t to 1 239 g/t.Additional economic benefits was over two million six hundred nine thousand yuan and technological transformation achieved remarkable effects.
