Advanced Modelling for Scale-Up of Batch Flotation Results

The traditional approach to flotation scale-up testwork attempts to use a batch cell to replicate industrial performance, assuming that the lab cell works as a scale model of the full plant.Industrial experience has shown, unfortunately, that the results obtained by such an approach can rarely be relied upon, due to the difficulty of replicating in a batch cell the effect of variables such as plant throughput and circuit

1996-6-1  For fast floating minerals, a short column is adequate, while for slow floating minerals, a tall column is required. In this paper, flotation rate constant measurement from two modes of operation in a feed-line aerated flotation column, i.e. batch and continuous, is described. The results obtained from INCO's matte separation studies are presented.
