  • 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.

  • Gravity separation

    Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
