TWO-CHAMBER ELECTROFLOTATION COLUMN Russian patent published in 2021 - IPC B03D1/14 C02F1/465 

FIELD: mineral processing.

SUBSTANCE: invention relates to devices for electroflotation in the processes of mineral enrichment of thin sludge. A two-chamber electroflotation column provides the preparation of solutions and pulps with the separation of two types of water-gas emulsions, where the cathode chamber is saturated with micro-bubbles of hydrogen in a reducing medium, the anode chamber with micro-bubbles of oxygen in an oxidizing medium. The column includes a base housing with holders on which the anode chamber and the cathode chamber are placed, while the cathode chamber is provided with a base in the form of an inclined membrane made at an angle of 15 degrees to the base housing and the bottom surface of the inclined membrane facing the anode chamber. Moreover, the anode and cathode are located on both sides of the inclined membrane that separates the anode and cathode, and the cathode chamber and the anode chamber are connected to each other through a shut-off valve to adjust the redox properties of the medium.

EFFECT: increase in the technological efficiency and intensification of the electrolysis process by providing the preparation of solutions with deep separation of two types of water-gas emulsions, one of which is saturated with micro-bubbles of hydrogen in a reducing medium, the second with micro-bubbles of oxygen in an oxidizing medium.
