Flotation equipment mainly includes flotation machines and auxiliary equipment (stirring tanks, applicators, etc.). In general, Flotation Equipment is mostly standard equipment, and flotation auxiliary equipment is mostly non-standard equipment. After the ore is wet-milled, the mineral substantially dissociated by the monomer is adjusted to a concentration of the slurry which is thoroughly mixed with the flotation reagent in a stirred tank and then sent to a flotation machine where it is inflated and Stir. The floating target mineral adheres to the bubble, forms a mineralized foam layer on the surface of the mud, scrapes off with a scraper or overflows from the overflow to become a foam product (concentrate), and the non-foam product is discharged from the bottom of the can.
With the continuous improvement of flotation theory research and flotation equipment technology, according to the working principle of flotation equipment, the existing flotation equipment can be divided into mechanical agitation flotation equipment, flotation column and reaction/separation flotation equipment. The mechanical flotation machine can be divided into a self-priming flotation machine and an aerated mechanical agitating flotation machine according to the inflation mode. The flotation column belongs to a non-mechanical stirring flotation device and is the basic work of the reactor/separator. The principle of the PE flotation device is similar to that of the flotation column. The aerator is placed outside the tower and the tower is used alone as a separator to take full advantage of the integrated force field. The flotation device has a fast flotation speed, good performance and good development prospects.
The slurry is fed into the impeller through the feed pipe, and the centrifugal force generated by the rotating impeller is thrown into the groove, and a negative pressure is generated under the cover plate, and the intake pipe automatically inhales. The sucked air and the supplied slurry are mixed together at the upper portion of the impeller and thrown into the water tank, thereby generating a negative pressure, so that the air is continuously sucked in. The prepared slurry, floating minerals are carried by bubbles to the surface to form a mineralized foam layer, which is scraped off by a scraper to obtain a concentrate.
Recovery losses in the flotation circuit should be considered as lost opportunities. Zhejiang Golden Machinery Factory analyzes mineral release data and establishes a flotation loop simulation model to determine opportunities to improve flotation loop performance.
