摘　　要：德兴铜矿大山选矿厂160 m^(3)浮选工艺流程来矿扰动频繁,浮选槽液位、充气量和浮选药剂添加量等关键变量主要依据操作人员对现场泡沫状态的主观认识进行调控,为了提高生产效率,稳定矿物浮选指标,节约资源及人力成本,进行了浮选智能控制系统的工业应用研究。通过在160 m^(3)浮选流程的关键点位安装泡沫图像分析仪,引入了基于规则的浮选专家系统。浮选专家系统应用后,160 m^(3)浮选生产流程稳定性得到了提升,铜粗精矿品位波动明显减少。The 160 m^(3) flotation process in Dashan Concentrator of Dexing Copper Mine has feeding frequent disturbances.The key variables such as flotation tank liquid level,aeration amount and flotation re⁃agent addition amount are mainly regulated according to the subjective understanding of the operator on the on-site foam state.In order to improve production efficiency,stabilize mineral flotation index,save resourc⁃es and labor costs,the industrial application of flotation intelligent control system is studied.A rule-based flotation expert system was introduced by installing a foam image analyzer at the key points of the 160 m^(3) flotation process.After the application of flotation expert system,the stability of 160 m^(3) flotation production process has been improved,and the fluctuation of copper rough concentrate grade has been significantly re⁃duced.
