Analysis of Lead-Zinc Sulfide Ore Flotation

Lead-zinc ore is a polymetallic mineral rich in elemental lead and zinc, mainly in lead-zinc sulfide and lead-zinc oxide ore. Among them, lead-zinc sulfide ore is an easy-to-select ore; lead-zinc oxide ore is a difficult-to-select ore. Due to the increasing global demand for lead-zinc mineral resources, both lead-zinc ores are valuable for mining.
