In addition, it should be added that because the desired separation cannot be achieved in a single stage, several coupled stages are used, which are called flotation circuit. The behavior of the whole process, therefore, depends on the configuration of the circuit and the chemical and physical structure nature of the treated pulp [ 14 ].
