摘要：

Dynamic models of pulps in industrial flotation cells are presented with emphasis on the modelling of their chemical conditioning. They are reduced to steady state models that can be combined to describe banks and networks of cells. Kinetic characterization of minerals in the plant is outlined on the basis of samples from appropriate points, their analysis and simulation between such points, in order to model the solids transfer from pulp to froth in the cells. Models of the froth layers and studies of their surface views are reviewed. Images of froths have been recorded in two plants and results of their analysis are presented. Scene analysis is considered a valuable means in acquisition of new information of processes in flotation cells. (C) 1997 Elsevier Science B.V.
