Mineral Flotation Column Equipment
Column flotation of its cross-section shape of round, square or top of the next round. From the upper to the ore slurry into the tube to evenly into the flotation column. Compressed air is inflated by the cylinder chamber through the bottom of the set of vertical pipes filled the air column. The formation of a large number of small bubbles evenly distributed throughout the section, the slurry under gravity down slowly, slowly rising bubbles from bottom to top, and the pulp to be useful in selected minerals in the column continuously met.
Column Flotation Process Of Iron Ore
Convective movement of the pesticides used in the role of the mineral to be selected will be attached to rising bubbles on the surface, the formation of mineralization in the upper cylinder foam layer, the scraper to scrape into the concentrate or from the overflow tank, while the remaining mineral cone from the lower end of cylinder tailings discharge pipe.
There is also a self-overflow-type flotation column. From the overflow-type flotation column is upper body, lower body composed of the middle cylinder and the entire cylinder is circular. Column flotation in the possession of a variety of depth to the mine, its mine points to vary the size of the visual column diameter, divided into three, four and eight. Inflatable flotation column by column from the bottom of the wind the wind the source chamber through the duct into the vertical set of porous plastic air tube.
The aircraft’s main structure is usually a cylindrical device with inflatable cylinder, the cylinder body with a device to the mine, foam and foam overflow tank or scraped off device, compressed air input pipe and wind bags.

Column flotation work, the better to reconcile the pulp from the Pharmacy in the upper cylinder unit to the entry to the mine; compressed air and wind through the input pipe network packets, and then through the porous medium from the bottom of the drum into the cylinder, so that the body formed in the column a large number of small bubbles. Mineral particles under gravity down slowly, air bubbles rise through the downward movement of the floating pulp, mineral particles and air bubbles through the counter-current contact and collision, to achieve the bubble selective mineralization.
Ore mineralization bubbles rise to the surface together form a floating layer of foam, spill or scraped off with a scraper after that concentrate; tailings from the column base with lifting device discharge. Since the slurry to the column inlet to the body known as the selection of district capitals, the main role is to improve the quality foam products; by the end of the pulp to the entrance to the column called capture zone, the main role is to capture the purpose of mineral surfaced want to improve recycling rate.
The Main Advantages Of The Flotation Column Technology:
● Improved recovery
