Description

Mining flotation equipment and flotation process thereof

Technical Field

The invention relates to the field of mining flotation equipment, in particular to mining flotation equipment and a flotation process thereof.

Background

Flotation refers to the use of surfactant-foaming agents that generate large amounts of bubbles. When air is introduced into water or air enters the water due to the stirring of the water, the hydrophobic end of the surfactant is oriented to the air of the bubbles at the air-liquid interface, and the hydrophilic end is still in the solution to form the bubbles; another surfactant (generally a cationic surfactant, also including fatty amine) which has a trapping effect is adsorbed on the surface of the solid ore fines. Flotation machines generally consist of a tank containing the pulp, an agitator to stir the pulp, an aeration device to produce froth, and a froth scraping device to discharge the froth. Aerating device is connected with the agitator, and aerating device produces the foam, and the foam carries out the enrichment with the trace mineral substance of ore pulp, and the agitator stirring drives the foam and floats on the ore pulp liquid level, scrapes the bubble device and scrapes out the cell body with the foam that floats on the liquid level and collect, and then realizes drawing and utilizing of useful mineral. However, in the actual production process, the height of the liquid level of the ore pulp is easy to change, so that the height of the foam layer is changed, and the ore pulp is often scraped by the foam scraping device when bubbles are scraped; therefore, the mining flotation equipment and the flotation process thereof are provided.
