As in most lead-zinc flotation operations, lead is separated first, followed by the zinc flotation stage. Due to the nature of the ore, lead minerals are frequently released from their gangue in coarse sizes, while zinc minerals need comparatively more grinding to produce the appropriate degree of liberation from accompanying gangue …

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

Due to the strong hydration of lead–zinc oxide minerals and the easy dissolution of metal ions on the surface, the flotation separation of lead–zinc oxide ores remains a major challenge to date. Therefore, sulfidation reconstruction of oxidized lead–zinc minerals prior to flotation is crucial for altering their surface properties.
