A review of the research on triboelectric separation technology Miner. Eng. (IF 4.9) Pub Date : 2024-08-03 Ruoxi Zhao, Zhenxing Zhang, Xuejie Bai, Haifeng Wang, Hao Zhang, Juan Hao, Chengxu Wang
Triboelectricity is a common phenomenon in daily life, and its application in the industrial field is becoming increasingly widespread. As a dry material separation technology under no-water conditions, triboelectric separation technology has the characteristics of low cost, environmental friendliness, and especially significant advantages in water-scarce regions. With the continuous growth in global

Optimizing coarse chalcopyrite separation in fluidized bed flotation: Role of the self-generated bed Miner. Eng. (IF 4.9) Pub Date : 2024-08-03 Qi He, Chuanfu Chen, Qinglin Yin, Shihao Ding, Yijun Cao, Xiahui Gui, Yaowen Xing
Coarse particle separation is important in mineral processing. In this study, the performance of coarse chalcopyrite ore separation (−600 μm, Cu grade 0.375 %) by fluidized bed flotation (FBF) was investigated and the basic function of fluidized bed on the particle separation is discussed. The chalcopyrite grain size distribution mainly ranges from 50 to 300 μm, with over 80 % of the grains being liberated
