Aiming at the problem of series parameters of agitation/flotation cells,the hydrodynamics characteristic of these cells was analyzed; The relevant impeller peripheral speed model, namely the RPS model, was put forward. The typical parameters of agitation/flotation cells at home and abroad were examined and some correlative data were processed. The result shows that the RPS model is in good accordance with the parameters well approved by products all over the world, indicating that the model is useful in the design of agitation/flotation cells. The use of this model and some correlative auxiliary ones as the basic models for determining the series parameters of agitation/flotation cells can enhance the quality of product.
