Study on the Effect of Magnetization Treatment of Flotation Reagents on Bubble Movement Behavior.

In order to explore the effect of magnetization on bubble motion behavior under different flotation agent systems, the three reagent solutions of sodium oleate, pineol oil and secoctanol were magnetized by laboratory self-made magnetization device, and the influence of magnetization on them was summarized by observing the bubbles generated in the self-made sink. The test results showed that the maximum velocity of bubbles under the sodium oleate system increased by 7.85 mm/s, the acceleration increased by 97 mm/s², the deformation coefficient of bubbles decreased by 0.19, the bubble merger time and bubble beating times increased by 0.25 s and 74 ms respectively compared with the unmagnetized conditions, and the bubble merger and bubble beating time changes significantly and the maximum speed increased by 9.43 mm/s when the magnetic induction intensity of the bubbles under the pine oil system was 100 mT. Under the secoctanol system, the bubble merger and bubble beating time changed significantly when the magnetic induction intensity was 150 mT, and the maximum velocity of the bubble increased by 3.03 mm/s at 300 mT. The experiments show that the magnetization treatment with 150 mT magnetic induction intensity has a favorable effect on the flotation behavior of sodium oleate solution. The largest differences in bubble deformation coefficient and beating time under sodium oleate, pineol oil and sec-octanol were at 150, 100 and 150 mT, respectively, and the influence of magnetic induction intensity on bubble velocity was also different under different solution systems. In addition, the rate of rise of sodium oleate has two peaks, while pineol oil and secoctanol have only one peak. Magnetization has obvious effects on all three solutions, and the research results have certain guiding significance for optimizing the application of magnetization treatment in flotation.
