Beneficiation methods for extracting gold from polymetallic ores can vary depending on factors such as the mineralogy of the ore, the presence of other metals, and the desired end product. Generally speaking, the beneficiation methods of polymetallic gold ore include gravity separation, flotation, cyanidation and amalgamation,etc.

Sulfide gold ore is a rock gold ore in which natural gold and sulfide (usual pyrite) coexist. The symbiosis of natural gold and sulfide means that pyrite is a gold-carrying body. Under normal circumstances, the sulfides are extracted together in the beneficiation process, so that the gold recovery rate can be guaranteed.

The adsorption of PAX or ADD on the gold ore is chemisorption process and the compound collector has a strong chemisorption capacity. The novel closed-circuit flotation process using compound collector develops an excellent beneficiation effect and provides a prospective and effective approach to concentrate low-grade gold ore.
