Sericite from Graphite by Using a Surfactant: MF
2017.5.7 flotation can not only cause the minerals that must be depressed to become hydrophilic but also increase the particle size of these minerals. Hence, bubble entrainment and mechanical entrainment in flotation can be weakened [15]. During graphite flotation, it is almost impossible to avoid the entrainment of sericite into graphite concentrate.
