• Flotation | GTK

    Flotation is the most common beneficiation method used for ores that contain metal and industrial minerals. Flotation was developed for the beneficiation of minerals, but it can also be used for the treatment of recycled materials, remediation of contaminated soil, de-inking of paper, and water treatment, for example.
