  • Recovery of iron from iron ore slimes by selective flocculation

    It may be seen that the settling rate of iron ore slimes decreases with increasing pulp density and increases with increasing pH. However, with PAM additions greater than 0.09 mg/g the iron grade decreased, with increasing recovery, which may be attributed to the haematite particles being covered by excess polymer and
