Abstract: Baixiangshan concentrator is faced with the prominent problems of fine disseminated parti ⁃ cle size of raw ore and high magnetic iron content of total tailings.These two factors seriously restrict the improvement of metal recovery rate in the concentrator.Therefore,the research and industrial application of new high-efficiency coarse-grained wet magnetic separator and disc magnetic separator were carried out. On the basis of the laboratory test of the system ,it is determined that one T-CCT1550 new high-efficiency magnetic separator is used for coarse-grained wet separation ,and two PC16-8 disk magnetic separators are used for the technical transformation and industrial test of the total tailings scavenging.The application re⁃ sults show that the new high-efficiency coarse-grained magnetic separator reduces the total iron grade by 0.25 percentage points,the magnetic iron grade by 0.9 percentage points,and the concentrate TFe recovery rate by about 1.08 percentage points.The total iron grade of the total tailings of the disk magnetic separator is reduced by 0.63 percentage points,the magnetic iron grade is reduced from 1.82%to 1.29%,and the iron metal recovery rate is significantly improved.The research results not only bring considerable econom ⁃ ic benefits to Baixiangshan concentrator,but also provide valuable experience and technical support for tail ⁃ ings treatment and resource recovery of similar mines.
