Refractory flotation machine from this supernatural power

Refractory flotation machine from this magical wide foaming agent is generally a heterogeneous surface active material. It contains polar groups in its molecule. At the other end of the molecule is a polar group. Due to the structural asymmetry in the foaming agent molecules, the foaming agent is preferably adsorbed on the gas-water interface after a large amount of air is filled in the frothing slurry. The hydrophobic, non-polar base force exits the water in open air and moves to the surface of the water, while the hydrophilic polar base portion tries to enter the water. The size of these two trends depends on the comparison of the strength of the polar and non-polar groups of the molecules. For example, if the composition of the non-polar group is large, the molecule moves to the surface tension. The phenomenon of spontaneous enrichment of substances at the surface layer is called adsorption.

Due to this oriented adsorption of the blowing agent molecules at the water-air interface, the surface tension of the water-air interface is reduced, making the dispersed bubbles in the water tough and stable. Two-phase (air and water) stable foams were formed. The surface of the bubbles formed in the slurry is accompanied by a large number of hydrophobic mineral particles. This kind of bubbles attached with mineral particles is called a three-phase foam. In a three-phase foam, the slurry becomes a barrier to the merger of bubbles, while at the same time preventing the flow of water between the bubbles. Avoid the direct contact of air bubbles, to help the stability of the three-phase foam, higher than the unmineralized two-phase foam.
