low copper ore fluidizing bed separator

  • Beneficiation of copper ores based on high-density

    For the response of gas velocity, under a low gas velocity, the bed expansion rate is small, and the bed activity is poor. The copper ore particles in the bed have greater resistance to movement and cannot be effectively sorted. When the gas velocity is too large, the gas content in fluidized bed increased.

  • Beneficiation and upgrading of coarse sized low-grade

    The results suggested notable beneficiation efficiency of coarse sized bauxite via dry fluidized bed separator. Moreover, the separation efficiency of coarse sized bauxite gradually declined with decreasing size fraction, which indicated that the dry-based fluidized bed separator had a low limit size of feeding for ore separation.
