San Diego, USA 5. CONCLUSIONS AND FUTURE WORK A flotation cell model has been developed. A practical approach has been used for tuning, which uses data commonly available on real plants. A case study has been presented, in which the model has been used to reproduce the behavior of an entire primary flotation cell.

Unlike conventional mechanical cells, column cells are tall vessels ranging in height from 25 feet 7.6m to more than 50 feet 15.2m. The surface area of a column cell is smaller than that of a mechanical cell which helps to promote a stable and deep froth.
