flotation technology to recover fluorspar

  • Column Flotation Testing Better & Improved Recovery

    The recovery scheme consisted of (1) grinding the ore to minus 48 mesh, (2) fluorite rougher and cleaner flotation, (3) desliming the rougher fluorite flotation tailings at 20 µm, (4) mica flotation, and (5) silicate rougher flotation. Acid-grade fluorspar, mica, free silica (SiO2) sand, and low-grade beryl (Be3Al2Si6O18) concentrate were produced in a 100 lb/h continuous column flotation unit (CCFU).
