The effect of regrinding on the design of flotation circuits

01/09/2020  However, the design of flotation circuits based on optimization is a complex task due to the non-convexity of the model and the inclusion of binary variables, making it difficult to obtain a global optimum solution. In other words, usually the design problem has multiple local optima, and the non-convexity of the model makes it difficult to find the globally best solution. The mathematical ...
