Gold Flotation

Flotation is one of the most widely used methods to process gold ores, especially suitable for sulfide gold ores with high reproducibility. This method is suitable for processing gold-bearing sulfide ores with fine gold particles and good flotability. In the flotation process, sulfide ores are enriched in sulfide concentrates as gold carriers.
