Galena–Pyrite Bulk Flotation. The particle size has a significant effect on the flotation behaviors of minerals; therefore, the effect of grinding fineness (−0.074 mm) on galena -pyrite bulk flotation was firstly investigated and the results are shown in Fig. 2a. As can be noted that the recovery of lead, zinc, and sulfur was increased simultaneously …
