    Oct 01, 2020 · An XFG-type flotation machine (Changchun, China) with a 40-mL Plexiglas cell was employed for flotation testing at the same speed (1700 rpm) used in our previous works , . The mineral pulp for single mineral flotation was prepared by mixing a 2.0-g sample into the cell with approximately 38 mL of DI water, and the pulp was agitated for 1 min. HCl or NaOH was used to adjust the pH

    flotation circuit - an overview | sciencedirect topics

    Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth

    Contact Cell Flotation. The flotation contact cell is a slurry aeration device with no moving parts. The contact cell consists of two main components: The contactor is a chamber in which feed slurry and flotation air are brought together under pressure. Pressure is maintained by a restriction located at the downstream end of the contactor

    Froth flotation cells then aggressively bubble air through the slurry. The air bubbles attach to the hydrophobic particles in the slurry and float them to the surface creating a mineral froth at the top of the flotation cell. This concentrated mineral froth is then collected from the surface of the flotation cell
