The application of the flotation method is regarded as a significant achievement in the mining technology in the 20th century. Besides the continuous disposition of the increasing various ores and opening new ways, flotation plays a vital role in promoting and improving metallurgical technological and economic indicators, comprehensively recycling all kinds of valuable components. At the moment, 90% of the nonferrous metal mineral output capitalizes on the flotation method for recycling. It is reported that almost the entire ores and mineral raw materials can adopt the flotation way to get processed. In addition, the flotation method is also used in the comprehensive recovery aspect of the metallurgy semi-finished products as well as these perspectives like salts, borax, rubber raw materials, paper, sugar refining, and chemical processing of raw materials etc.
The working principle of the mechanical agitation and air self-priming flotation machine (including the impeller flotation machine and the rod wheeled flotation machine) is basically the same: it takes advantage of the negative pressure created by the rotation of the impeller or rod wheel, and inhales air via the quill shaft, ultimately forming the bubbles. The air bubbles blend fully with the ore pulp under the stirring and projectile impact of the impeller or the rod mill. These useful mineral particles selectively adhere to bubbles under the influence of the collector, they float to the pulp surface then scrapped by the scrapper into the fine mineral chute. Therefore the sorting operations are finished.
Flotation ore dressing production line consist of the process of mining, crush, and flotation of the ore, during the process, they may cause seriously pollution to the environment. At present, many mines have taken positive environment protection measures, but these are far from enough, the mining environment in our country still needs to be improved.
Induced Gas Flotation (IGF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by injecting air bubbles into the water or wastewater in a flotation tank or basin. The small bubbles adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.
The feed water to the IGF float tank is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to flocculate the suspended matter.
The bubbles may be generated by an impeller, eductors or a sparger. The bubbles adhere to the suspended matter, causing the suspended mater to float to the surface and form a froth layer which is then removed by a skimmer. The froth-free water exits the float tank as the clarified effluent from the IGF unit.
The green technology is the point that the big enterprises and mining manufactures must pay much attention. During the working process, the environment pollution of the classifier, magnetic separator, belt conveyor, and crusher can reduce to the degree of harmless to people when use the green technology and optimize production environment.
