Comparison of Flotation Column and Mechanical Cell in Coal Flotation

Flotation is universal method to fine coal processing. Selectivity and efficiency of flotation depends not only on surface characteristics of particles, but also on hydrodynamic condition in flotation cell. The goal of the research was to compare flotation column and conventional mechanical flotation cell in coal flotation. The tests was carried out in both flotation cells in the same conditions. The results indicated that the mechanical cell has greater recovery, whereas the flotation column has a considerably better selectivity since it provides a concentrate of better quality.
