Abstract:With the characteristics of poor, miscellaneous and fine mineral resources becoming more and more prominent, the problems such as low grade of selected ore and excessive amount of waste rock are prominent. It is an important way to solve this problem to develop intelligent separation technology and apply it to preenrichment before ore preparation. Among them, X-ray diffraction topography (XRT) sorting imaging scheme has become one of the mainstream applications in the field of non-ferrous metals mining, and have achieved better enrichment effect in tungsten ore, lead-zinc ore, molybdenum ore and other fields, greatly improving the economic benefits of the mine. This paper aims to introduce the development of XRT and its research status at home and abroad, including the principle and characteristics of the separation equipment and the application of different non-ferrous metal fields.
