Description

Technical Field

[0001] The utility model relates to the technical field of magnesite flotation impurity removal, in particular to a magnesite flotation tailings slag removal device. Background Art

[0002] Magnesite is a carbonate mineral with a chemical composition of MgCO3 and a trigonal crystal system. The tailings of magnesite contain a lot of impurities, and flotation machines are often used to remove impurities from the tailings. During flotation, the tailings need to be crushed into powder first, and then the powder, flotation agent and water are added to the flotation machine. The flotation machine introduces bubbles into the liquid, and the mineral particles in the liquid are driven upward to the water surface through the bubbles to form flotation foam, while the impurities sink to the bottom of the water, thereby separating the minerals from the impurities. However, the position of the air pipe for conveying bubbles in the existing flotation machine is fixed, resulting in a roughly fixed rising path of the bubbles output, resulting in uneven dispersion of the bubbles in the liquid, affecting the flotation efficiency. Therefore, in view of the above situation, it is urgent to develop a magnesite flotation tailings slag removal device with uniform distribution of bubbles, so that the bubbles can fully separate the mineral particles from the impurities and improve the impurity removal efficiency, so as to overcome the shortcomings in current practical applications and meet current needs.

The material in the screening box 1 is stirred and bubbles are delivered by the stirring and air supply mechanism 5, so that the flotation agent and the magnesite powder are mixed more fully. At the same time, useful mineral particles are brought upward to the water surface by bubbles to form flotation foam, and impurities are left at the bottom of the screening box 1. The flotation foam is then pushed into the collection box 2 by the froth cleaning mechanism 3 for collection. After use, the plug 102 is removed, and the impurities are discharged from the slag discharge port 101. Then, water is sprayed into the screening box 1 through the flushing pipe 4 for flushing.
