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.
Reverse flotation includes rough flotation and clean flotation, through which Limonite iron ore would be greatly upgraded. The iron concentrate obtained is of 56.73% in content. The middlings return to magnetic flotation, forming a close-circle process.
Henan Hongxing mining machinery Co. Ltd. is mainly engaged in crushing equipment, sand making equipment, milling equipment, concentrating equipment and building material which are widely used in metallurgy, mining, chemical industries, building materials, coal, refractory materials, ceramics and other industries. Concentrating equipment can be classified into hematite mineral concentrating equipment, limonite concentrating equipment, magnetite concentrating equipment, copper separating equipment etc.
Now let’s take magnetite as an example and make a brief introduction of it. The development of magnetite concentrating equipment is mainly concentrated on magnetic separator and screening devices. While the implement of the strategy “improving the purity of iron”, it is becoming more urgent to improve the quality of iron concentrator. Key technologies to achieve it: (1) anti-float technology and efficient collector (2) fine magnetic deep separating equipments (3) fine sieve technology (4) extensive using of column flotation in the anti-flotation of iron ore concentrating rather than the traditional flotation machine.
With in-depth development of the domestic and foreign high-performance permanent magnet materials, the industrialization of magnetic separation equipment as well as the constant optimization, upgrade and promotion of traditional permanent magnetic separator magnetic system and body structure has accelerated the process that permanent magnetic separator equipment gradually takes place of electromagnetic separation equipment. With the application of automatic control technology and monitoring technology in domestic and foreign mining enterprises, the automation level of mining equipment manufacturing is improved correspondingly and the accuracy requirements of the field of magnetic mineral separation is becoming higher and higher.
Over the years, the machinery industry in China mainly participates in the second level of competition in the international market with the advantage of huge manufacturing capabilities and low labor costs to win the market position in international competition. Therefore, only forming a stronger advantage in the first level and the second level can we enhance our international competitiveness China's machinery industry as a whole.
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.
