and particularly<5μm fully liberated Platinum Group Minerals (PGMs) were being lost to tailings. They commented that this problem was unlikely to be solved by introducing more power into conventional flotation cells and that different flotation technology would be needed to overcome the problem.

The largest mechanical flotation machines available today have unit volumes in the range of 38 to 42 m³ (1,350 to 1,500 cft). In fact, the motivating forces of increasing capital and energy costs and decreasing ore grades, which created the need for large flotation cells, not only still exist, but are becoming more critical.
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
