| Abstract: | Through the introduction of process and production index of 500 thousand t/a and 4 million t/a concentration plant,the characteristics of the oredressing process of Dahongshan iron mine deep（Ⅱ1 iron group） were analysed,and middlings was separated by using of stable or high gradient magnetic separator in tailings,then the utilization rate of resources was improved.Combining with the production practice,the existing problems and its solutions of Dahongshan 4 million t/a concentration plant were analysed.The technical innovation of process and production practice in Dahongshan 500 thousand t/a and 4 million t/a concentration plant,which opened a new way for the oredressing process in deep of Dahongshan iron mine. |
