Using a new patented process for removing oxidation products from the surfaces of sulphides, the flotation of ultrafine nickel minerals has been raised markedly in both bench and plant scale tests. For the flotation of ultrafines, the importance of entrainment cannot be over-emphasized.
If the agitation is severe and there is a lot of mineral being dislodged, an over load or mineral loss may result due to the lack of cell space for the mineral. Either band aid method will be costly due to the loss of efficiency of the froth column, raising the pulp level to speed the over flow of the froth will increase retention time but ...

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.
