Flotation machine is replaced by flotation column applied for low grade scheelite fine processing upon analyzing the technological transformation reasons and working principles of flotation column. Technology demonstrations of lab experiments and semi-industrial tests reveal that flotation column modified fine processing system achieves expected results. The application of flotation column to scheelite fine processing improves recovery rate, reduces energy consumption and increases production automation efficiency by comparing the energy consumption and production indexes before and after technology transformation.
