Flotation Circuit - an overview ScienceDirect Topics
In the literature, various methodologies for flotation circuit design have been proposed, with most using optimization techniques. In these methodologies, the alternatives are presented using a superstructure, a mathematical model is developed, and an algorithm is used to find the best option based on an objective function. The differences between these methodologies depend on the superstructure, the

Abstract The optimized operation of a flotation circuit is investigated analytically. The analysis gives a simple and exact solution for cases where the concentrations of streams can be characterized adequately by scalar values. The method can also apply to the general case with concentration vectors, for which the more intricate analysis has not yet been completed.
