Jun 01, 1995 height the original flotation columns marketed by column flotation co. of canada were 40--45 ft high  and this became, in essence, the standard. one advantage was that height was then not a factor and scale up could focus on the number and diameter of the columns required.
At a macro-level, efficiency in flotation can be driven using holistic engineering approaches. for example, hatch offers two solutions — mine to mill and grade engineering — that aim to increase the overall efficiency of mineral processing operations, inclusive of flotation.
Jan 01, 2000 flotation columns are common devices in cleaning circuits in the mineral processing industry. the operation and control of these columns often have the final responsibility for the quality of the concentrate grade and, to a less extent, for the recovery of the cleaning circuit.
