| Abstract: |
| With the continuous development and utilization of mineral resources in China, the amount of natural high-grade ore resources has gradually decreased, and low-grade ore has become the main source of mineral resources in China. Therefore, pre-selection and discarding have become a necessary mineral processing link. This paper focuses on five kinds of waste disposal technologies, including manual picking, photoelectric separation, magnetic separation, gravity separation and flotation. The equipment and working principle of different technologies in pre-selection and waste disposal are introduced. The advantages and disadvantages of various pre-selection and waste disposal technologies are pointed out, which provides a certain reference for the further industrial application of pre-selection and waste disposal technology. |
