  • Floatation of ultrafine coal Froth Flotation (Sulphide

    Froth Flotation (Sulphide & Oxide) People used to float -0.5mm coal in flotation cells in 1960s,70s and 80s, but now they have switched to -0.25mm flotation. It is recommended that maximum size particle that you try to float be 0.3mm. The reason is that 0.5mmx0.25mm flotation requires more residence time than 0.25mmx0 flotation.
