Electrolytic flotation

It is the use of an applied electric field, so that the floating mineral water electrolysis in the slurry, oxygen and hydrogen microbubbles precipitated as fine-grained mineral flotation of the auxiliary vehicle or vehicles.

The electrolysis reaction of water is as follows: H 2 O → H + + OH-

Hydrogenation at the cathode: 2H + +2e→H 2 ↑

Oxygen saturation at the anode: 4OH - ―4e→2H 2 O+O 2 ↑

In addition to the generation of microbubbles, the electrolysis gas itself is also a regulator. It is in an atomic state when it is precipitated from the surface of the electrode. Although the time is short, it has a certain influence on the surface action of the mineral and the flotation reagent, which can improve the selectivity. At present, electrolytic flotation is also in the experimental research stage.
