Several reasons contribute to the wide gap in the industrial application of the academic models. These include: 1) the lack of generality in the model, e.g., the model is limited to certain size ranges; 2) the academic models involve complicated mathematics 3) confusion about the order of the flotation rate, e.g., several authors proposed a first order rate model, whereas the others propagated

## Mineral processing Wikipedia

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
