· In this study, the flotation behaviors of gold and gold-associated sulfide minerals (pyrite and sphalerite) in a polymetallic sulfide gold ore were investigated using flotation kinetics parameters. It was found that high gold recovery (>90%) can be achieved by the selective flotation of pyrite and sphalerite.

· Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.

· Lead-Zinc-Gold-Silver Flotation: This Colorado mill, treating a complex lead-zinc ore carrying gold and silver values, uses a Mineral Jig and a “Sub-A” Unit Cell in the closed grinding circuit. The jig recovers coarse and fine heavy minerals (as soon as free) which are difficult to float due to size and specific gravity.
