Flotation Column
Flotation column is a new type of high efficient pneumatic flotation equipment without mechanical agitation. It works in the way of ore particles counter current contact with micro bubbles, which offers micro bubbles a chance for collecting particles. The micro bubble generation system can produce a large amount of tiny bubbles, which provides great surface area and more opportunities to impact contact with ore particles. It eliminates "short circuit" phenomenon of the useful minerals in the flotation process, and improves the flotation speed and recovery. Flotation column can offer thick and adjustable foam layer, and obtain high enrichment ratio with the cleaning effect of the cleaning water. Flotation column is often used to improve the concentrate grade. Flotation column can be used to deal with ferrous metals, nonferrous metals, and non-metallic minerals, as well as waste liquids and residues of chemical industry, paper making, environmental protection and so on, especially used in technical innovation of old mining companies and capacity expansion to achieve " greater, faster, better and more economical " .
Features and technology advantages
1.New type of micro bubble generator can produce small and uniform bubbles ,which is beneficial to collect fine particles.
2.The foam layer thickness is adjustable, and the enrichment ratio is far higher than that of flotation machine.
3.Static separation environment can reduce the probability of particle's falling off..
4.Compared with tradition flotation machine, flotation column can save power more than 30%.
5.Compared with self-absorbing flotation column, the pneumatic flotation column operates with lower energy consumption and less wearing.
6.The spraying micro bubble generator is not easy to be blocked and prevent the reverse flow of slurry.
7.The tailings valve is made of special materials, long service life.
8.The video monitoring system can be adjusted according to the operation condition timely.
9.Flotation column parameters can be controlled by computer, which greatly reduce the labor intensity.
Working principle
Flotation column adopting the micro bubble generator injects gas into the column, and produces a large number of micro bubbles; then the ore particles counter current contact with micro bubbles steadily and catch the hydrophobic mineral particles to produce froth concentrate. The height of the liquid level and thickness of the foam layer can be adjusted by level control system. The micro bubble generator can be replaced online and maintenance is convenient.
