Gold Flotation Process
Introduction Flotation is a common beneficiation method for gold beneficiation plants to treat rock gold ores. It is often used to treat sulfide mineral gold ores with high floatability. The flotation process can enrich gold in sulfide minerals to a greater extent, and the tailings can be directly discarded. The beneficiation cost is low. 80% […]
