Study on comprehensive utilization process plan of Anqing copper mine tailings.

Purpose;With the increase of mining years,the Anqing copper mine has gradually faced the problem of insufficient storage capacity of tailings dam. Therefore, the study of comprehensive utilization technology of tailings at the Anqing copper mine has been conducted, aiming to achieve the resource utilization of tailings, reduce the amount of tailings disposal,and extend the service life of the tailings dam. Method;Through the research on tailings production processes of Anqing copper mine,and the analysis of physical and chemical characteristics of the tailings, a comprehensive utilization process technology of tailings based on cyclone classification combined with vibratory dewatering has been developed. And by conducting industrial trial, the quality indicators and utilization efficiency of classified coarse tailings were analyzed. Result;The tests results show that the average content of particles finer than -- 74 jLtm of coarse tailings product is less than 15%,and the water content of coarse tailings product is approximately 18%, moreover the content of sulfur is less than 0. 5%, which all meet the requests of standards for construction sand. The industrial trial demonstrated that the comprehensive utilization capacity of the tailings is 30 t/h, with an efficiency of 48%, and can then reduce the tailings discharge by around 200,000 t annually, which can effectively alleviate the Anqing copper mine's problem of insufficient capacity of tailings dam. Significance;The related research results can provide guidance and practical value for mines facing similar challenges and contribute to the development of solid waste comprehensive utilization technology for metal mine tailings in China.
