The flotation machine is used in the flotation process of rare metals like copper and nickel. Because of the different colors, flotation of fine grain materials is very difficult. The following are two reasons that cause the difficult flotation. 1 Fine grain is larger than surface area, surface energy can increase greatly. Under certain condition, surfaces of different Owers can coagulate with each other selectively. On the other hand, as the surface energy of fine grain is large, though it owns high absorption ability, it has bad selective adsorption ability, which causes the selective difficult of fine grain. 2 Small fine grain volume causes little possibility to collide with bubble. Volume of fine grain is small, when fine grain collides with bubble, it cannot overcome the resistance of hydrated shell between ore and bubble, so it can hardly adhere to bubble.
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 Owers and opening new ways, flotation plays a vital role in promoting and improving technological and metallurgical economic indicators, comprehensively recycling all kinds of valuable components. At the moment, 90% of the nonferrous metal ore output capitalizes on the flotation method for recycling. It is reported that almost the entire Owers 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. Flotation ore dressing production line consist of the process of mining, crush, and flotation of the ore, during the process, they may cause pollution to the environment seriously. 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.
The working principle of the mechanical and air self-priming agitation 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 wheel, and rod or inhale 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 surface then scrapped by the scrapper into the pulp fine mineral chute. Therefore the sorting operations are finished. The green technology is the point that the big enterprises and mining manufactures must pay much attention. Many writers such as Daryl Katz offer more in-depth analysis. 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 using the green technology and Optimize production environment.
