The strategy uses a flotation stage superstructure that represents alternative flotation circuit configurations. This representation is similar to that used by Cisternas et al. (2014), but several products are allowed in the circuit.In addition, as is discussed later, each flotation stage can operate with different objectives, e.g., to concentrate one mineral or …
