摘　　要：针对我国浮选生产过程自动化程度普遍较低导致的资源消耗大、生产成本高、环境污染严重的问题,提出了由过程控制系统和制造执行系统两层结构构成的浮选生产过程综合自动化系统,讨论了该系统的体系结构、系统功能及控制策略。分别采用西门子Win CC和西门子STEP7对系统监控软件和控制软件进行开发,将该系统应用于某选矿厂的浮选生产过程,提高了精矿品位和产品回收率,降低了尾矿品位和人员消耗,从而降低了资源消耗和生产成本,实现了浮选生产过程的优化控制、运行和管理,取得了显著成效。In allusion to problems existing in flotation processes in China, such as resource consumption, high production cost and serious environmental pollution, caused by the common low degree of automation, an integrated automation system made up of the process control system and the manufacturing execution system for the flotation process is put forward, and the architecture, system function and control strategy of the system are discussed in the paper. Monitoring software and control software of the system are developed respectively by Siemens WinCC and Siemens STEP 7. The system is applied to the flotation process in a concentrator, the concentrate grade and the recovery rate of products are improved, the tailings grade and human consumption are reduced, then the resource consumption and production cost are reduced. Finally the optimal control, operation and management are realized in flotation processes and a remarkable application result is obtained.
