Mchanistic study on the flotation of barite with C<sub>18</sub>H<sub>33</sub>NaO<sub>2</sub> under microwave radiation based on UV-visible spectrophotometric analysis

In this study, based on the pure mineral flotation test of barite, effect law microwave barite was investigated by using UV-visible spectrophotometer (L5), solution chemistry calculation and Zeta potential, scanning electron microscope (SEM), other testing methods; at same time, red kinetic analysis carried out to deeply explore mechanism C18H33NaO2 under radiation. Mineral tests show that deionized water after treatment, recovery increased 2.67%, 3.35%, respectively, while pulp chemically added ore action reduced 2.90%, 8.51%, respectively. Microwave can improve (up 95.27%), for heating positive electrical properties surface its specific area adsorption rate sodium oleate thereby improving recovery. The kinetics revealed k-value primary model is most informative among four models kinetics, fitting results truly reflect before action. By analyzing experiments trapped action, we provide an important reference efficient behavior barite. reference.
