Flotation device

Abstract

The invention provides a flotation device, and relates to the field of ore flotation. The flotation device comprises an air inlet mechanism, a ventilation plate, a U-shaped plate, a sweeping plate mechanism, a collecting cavity and a flotation mechanism. The ventilation plate is arranged on the inner wall of the bottom end of the U-shaped plate. The air inlet mechanism is arranged above the ventilation plate. Air inlet holes are formed in the ventilation plate. The air inlet mechanism is communicated with the U-shaped plate. The collecting cavity is arranged on the inner wall of the U-shaped plate. The flotation mechanism is arranged on the ventilation plate. The sweeping plate mechanism is arranged above the flotation mechanism, and one end of the sweeping plate mechanism is fixedly connected with an output shaft of a rotating motor through a coupling. According to the flotation device, mineral powder deposited at the bottom can be blown into the flotation mechanism again, the situation that the flotation effect is affected due to the fact that the mineral powder is separated out and deposited at the bottom is prevented, contact between bubbles and the mineral powder is enhanced, the adsorption effect of the bubbles on the mineral powder is improved, and meanwhile separation of solid impurities can be accelerated through generated vibration.

Description

technical field [0001] The invention relates to the technical field of ore flotation, in particular to a flotation device. Background technique [0002] A method for flotation separation of pyroxene in magnetite ore, which belongs to the technical field of mineral engineering and material separation, can solve the problem of difficult separation of pyroxene-type iron-containing silicate minerals in magnetite ore. Firstly, the ore is crushed to The particle size is 0.074mm, accounting for more than 50%, and then add water to the finely ground ore sample in the flotation tank to stir the slurry to form a certain concentration of slurry, and adjust the pH of the slurry, and then add anion collectors and cations in sequence according to the dosage ratio of the chemicals The collector is stirred for a certain period of time, and finally the flotation is scraped. The product in the flotation cell is filtered and dried to obtain enriched magnetite. [0003] When performing flotat...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a flotation device, which solves the problem that when the magnetite ore sample is flotation, since a part of the ore powder will be precipitated and impurities will be deposited at the bottom, multiple processes are required for repeated flotation. , affecting work efficiency, and the impurities in the solution are also difficult to separate at one time. Some impurities tend to adhere to the air bubbles together with the ore powder, which affects the accuracy of magnetite flotation.
