Improving the intelligent methods of management of processes of enrichment on the basis of visiometrics analysis of the grade of the ore

Full Text:


For the flotation process is effective using of open control loops, which are used as input parameter the ore quality. To determine the quality of ore is carried out on-line analysis of its elemental and mineral composition and structure. The basis of the operational analysis is the measurement of X-ray and visible light. To improve the accuracy of determining ore mineralogical composition, new techniques and facilities have been developed. At the conveyor ore analysis, special lighting systems were tested, using alternating focused and flat light fluxes. Such systems provide highly accurate in-stream measurements of ore properties. A special flatbed facility for optical spectrumbased estimation of fine-crushed ore has been developed, being incorporated into the existing system of ore sampling and analysis. Application of the flatbed facility renders possible a high accuracy of determining ore mineralogical composition. Modern systems for optical spectrum-based estimation of ore grade provide a basis for effective automated control of ore beneficiation processes, based on the principle of advanced ore grade control. The systems implemented at the "Erdenet" processing plant (Mongolia) contributed to increasing copper and molybdenum recovery.
