In addition, Eric et al. [23] investigated the flotation performance of gold in porphyry copper-gold ore by first-order flotation kinetics, which indicated that an increase in flotation time of copper rougher stage cannot result in the increase in gold recovery and some gold particles can only be recovered by pyrite flotation. However, none of ...
