    Jul 09, 2018 Flotation constitutes a separation process that originated from mineral processing. Nowadays, wider applications have been found and compared to flotation for water and wastewater treatment. Stress in the present review paper was mainly applied to heavy metal ions recovery by flotation and the respective mechanism followed, being either ion, precipitate, or sorptive flotation

    Oct 28, 2021 Flotation is the most effective beneficiation process for phosphate ores and more than 60% of the phosphate concentrate products in the world are obtained by flotation . The collector plays an important role in the flotation process and cationic amine collectors are often used for desilication of collophane by reverse flotation [6,7,8,9,10,11]
