An experiment on flotation of calcite in pulp with pH of 8.0 and the dosages for sodium silicate and sodium oleate respectively at 300 mg/L and 1.5 × 10-4 mol/L was performed by using ultrasonic wave with the frequency at 40 kHz, for investigating the influence of ultrasonic power and sonication duration on the flotation behavior. The variation of sodium oleate content on the surface of calcite was analyzed by adsorption measurement, the chemical status of elements on the calcite surface was analyzed by XPS, and the variation of adsorbed reagents was also analyzed by zeta potential measurement. After 15 min-ultrasonication (40 kHz, 150 W), the flotation recovery of calcite can be increased from 8.5% to 82.7%. It is found that ultrasonication can bring in an increase in the adsorbed amount of sodium oleate on calcite, a decrease in the intensity of Si2p on calcite, and also an increase in the content of C1s. Meanwhile, the deconvolution of O1s spectrum shows reduction in the peak area of sodium silicate, but an increase in that of sodium oleate, and the surface zeta potential of calcite almost unchanged. The results indicate that the ultrasonication can induce a desorption of sodium silicate from the depressed calcite in the pulp containing both sodium silicate and sodium oleate, thus the freshly vacancy can be adsorbed by sodium oleate, leading to the significant improvement in floatability of calcite.
