Silver (Ag), atomic number 47, is a rare metal resource with dull-white color. In nature, most of the silver resources are associated with Lead-Zinc ores, except for a small portion in the form of simple substance or silver minerals. Therefore, the acquisition of metallic silver is relatively difficult. Flotation is the principal beneficiation method to concentrate silver minerals.

At present, zinc is produced from zinc sulfide minerals which are the primary source of zinc, and it is easy to separate the sulfide minerals from the gangue using conventional flotation techniques. As sulfide ores become depleted with the passage of time, the beneficiation of oxidized zinc ores has assumed great importance in recent years.
