Abstract:China "s copper resources have the characteristics of small deposit scale, many associated ores, low grade and complex material composition of deposits. Driven by the development of today "s new energy industry, the consumption of copper resources continues to grow. Due to the lack of equipment for sorting low-grade fine-grained copper ores, a large number of fine-grained copper ores are lost, resulting in a shortage of copper resources. In order to improve the recovery rate and grade of copper metal in copper mine and reduce the environmental pollution caused by the use of reagents, a separation method based on the coupling effect of rotary vibration and centrifugal force was proposed. The separation model of rotary vibration high gravity flow field of copper ore particles in Fluent was established to study the separation behavior, velocity distribution and particle concentration variation of different components of copper ore particles in rotary vibration separator. The results show that the particles of different components of copper ore are evenly distributed in the cylindrical section of the separator, and stratification and separation occur in the conical section. SiO2 particles and Cu particles have a ring with zero radial velocity at the periphery. The radial velocity of SiO2 particles is the largest in the central region, and the radial velocity of Cu particles is the smallest in the central region. The closer to the wall, the greater the radial velocity. The centrifugal force of SiO2 particles is small, and the particles move upward spirally to the overflow port under the combined action of the rotary vibration component force and the upwelling. The centrifugal force on the Cu particles is large enough to overcome the rotational vibration component force. Most of the Cu particles are enriched on the wall of the conical section and discharged along the underflow outlet. The recovery rate and enrichment ratio are 86 % and 14, respectively. Compared with the traditional high-gravity cyclone separation, the rotary vibration can make the bed loose, effectively solve the problem that the copper ore particles are easy to agglomerate during the separation process, and help to promote the stratification of different components of the copper ore according to the density difference, which can significantly improve the separation efficiency of the copper ore particles.
