  • Effect of particle size on the reverse flotation of

    The separation efficiency indexes of all the reverse flotation tests are compared in Fig. 20. It indicates that the selectivity of reverse flotation for mixtures of coarse or medium coal and fine silica is much higher than the others when 1 kg/t dextrin and 1 kg/t collector were used. As such reverse flotation can perform well for coal

    Four types of cationic collectors were tested and evaluated for their performance in the reverse flotation of silica from the spiral preconcentrate of Kudremukh iron ore. A stagewise flotation was conducted by adding the reagent in three stages. Starch was used to depress hematite. Silica flotation was found to be very sensitive to the amount of cationic reagent added.
