| Abstract: |
| 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. |
