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
