What Are The Influencing Factors Of Gold Flotation?
Usually, gold ore is recovered by carrier flotation, and the carrier mineral size can be separated by flotation by grinding operation. Due to the high density of gold ore, the flotation gold particle size is usually no more than 0.22mm, in order to facilitate flotation separation.
