复杂高品位硫氧混合铜浮选智能控制技术研究,

复杂高品位混合铜浮选工艺一直以来是选矿领域的研究热点和难点之一。同时,这种类型的浮选过程智能控制也属于行业空白。本文通过采用浮选过程专用的载流X荧光分析仪、泡沫图像分析仪对工艺过程在线监测,得到了反映混合铜浮选过程的重要工况参数,实现了流程的工况诊断。进一步通过研究基于模糊规则的浮选药剂添加与浮选机的液位充气量控制,实现了这一浮选流程的智能控制。通过本研究形成的控制系统,连续、稳定、可靠地应用于穆索诺伊选矿厂的生产过程之中,获得了较为明显的经济效益。

Research on Intelligent Control Technology of Complex High-grade Sulfur-oxygen Mixed Copper Flotation

The flotation process of complex and high-grade mixed copper has been one of the research hotspots and difficulties in the field of mineral processing. Meanwhile, this type of flotation of intelligent control is also a blank in the industry. In this paper, an online X-ray fluorescence analyzer and several forth image analyzers dedicated to the flotation process are used to monitor the process on-line, and important flotation parameters reflecting the mixed copper flotation process are obtained. It is also analyzed that the working condition diagnosis of the process. Furthermore, the intelligent control of this flotation process is developed by studying the addition of flotation reagents based on fuzzy rules of the flotation air and level control. The control system formed through this research has been continuously, stably and reliably applied to the production process of the COMMUS, and it has obtained obvious economic benefits.
