SU1585005A1 - Method of aeration of pulp in flotation - Google Patents

Abstract

The invention relates to mineral processing. The goal is to improve the performance of the flotation process by increasing the aeration of the pulp by increasing the number of collisions of liquid and gas jets. For this, solid flat and separate jets of liquid and gas are simultaneously formed in the pulp volume. Then, a separate jet of liquid is passed through a continuous flat stream of gas, and separate gas jets through a continuous flat stream of liquid. When the jets collide, air dispersion and pulp aeration occur. The aerated volume of the pulp is removed from the aeration zone, and a new volume of pulp is in its place. 4 il.

The purpose of the invention is to improve the performance of the flotation process by increasing the aeration of the pulp by increasing the number of collisions of the liquid and gas jets. For this, solid flat and separate jets of liquid and gas are simultaneously formed in the pulp volume. Then, a separate jet of liquid is passed through a continuous flat stream of gas, and separate gas jets through a continuous flat stream of liquid. When the jets collide, air dispersion and pulp aeration occur. The aerated volume of the pulp is removed from the aeration zone, and in its place comes a new volume of pulp. 4 il.

This invention relates to the enrichment of minerals by the flotation method and can be used in wastewater treatment and in the chemical industry.

The purpose of the invention is to improve the performance of the flotation process by increasing the aeration of the pulp by increasing the number of collisions of the liquid and gas jets.

The method of pulp aeration during flotation is as follows.

In the volume of the pulp, they simultaneously form continuous flat to separate liquid and gas jets, and pass separated liquid jets through flat gas jets, and separate gas jets through flat liquid jets.

The simultaneous formation of continuous flat and detached liquid and gas jets and the passage of separate jets through flat ones in one volume increases the number of jet collisions, thereby increasing the number of bubbles, their degree of dispersion, and the gas-liquid interface area. In the liquid formation, the jets can be used as a separately supplied liquid, as well as pulp from the volume of the flotation cell chamber. The method of pulp aeration during flotation can be carried out in flotation machines of pneumatic, pneumomechanical and mechanical types.

FIG. 1 shows a flotation machine in which the method is implemented.
