| Abstract: |
| This paper introduces the present situation of tin tailings resources in China, analyses the characteristics of tin tailings and the reasons why it is difficult to re-dress them, summarizes the results of reconcentration of tin tailings, points out the existing problems and shortcomings in the process of reconcentration and utilization of tin resources at present, and the main methods of reconcentration are gravity separation, flotation and combined process: the cost of gravity separation process is low, but the grade and recovery rate are low, and the flotation process is feasible. Better indicators were obtained, but the cost of reagents was high and the environment was polluted. The combined process indicators were good and the process was complex. On this basis, in view of the current situation of tailings reconcentration research, the corresponding thinking and suggestions are put forward, and the future utilization and development trend of tin tailings resources are prospected. |
