Development of lead zinc ore beneficiation technology

To understand the development of lead zinc ore beneficiation technology. In recent years, Pb Zn ore dressing technology in theory, technology and reagents have made many achievements. But at the same time, the theory of progress is relatively slow, to further accelerate the pace of research. In the mineral resources become increasingly tense today, in a multi metal sulfide ore is increasingly poor, fine, complex today, we must strengthen the theory study, the development of new high efficiency flotation reagents and flotation process improvement, in order to more effective recovery and utilization of Pb Zn and CO production resources. 2000~2004 lead zinc ore dressing technology has made great progress, the application of new theory and new technology to study the electrochemical flotation of lead-zinc sulfide ore was promoted by the technology progress of lead zinc ore dressing. Development and application of more and more new chemical processing in recent years, especially the combination and composite medicament on the development and application of rapid development. The composition can play a synergistic effect of various drugs, and strengthen the complex lead-zinc minerals in ores catch selectivity and separation, solve the problem of many complex flotation of Refractory Polymetallic Sulphide Ore, brings huge economic benefit for the ore dressing plant.

Development of processing technology of lead-zinc sulfide ore. In the research of mineral processing technology of lead-zinc sulfide ore in our country, the basic realization of the cyanide free process, made an example and lead zinc ore dressing technology and flotation reagents for the Pb Zn ore field. The lead and zinc mineral processing technology and production practice of many reports, research on theory of lead zinc ore dressing is more, especially showing a thriving trend in the study of lead and zinc Flotation Electrochemistry; lead and zinc ore dressing technology in and abroad are rarely reported, but many lead-zinc ore dressing mechanism and theory research. Process selection of lead zinc ore, ore type is selected according to the different, different processing methods, but also requires the lead-zinc mine different mineral processing equipment. Sulfide ore flotation method is used usually. Oxide ore flotation gravity separation and flotation or combined beneficiation flotation of sulfide, or baking, or re-election after treated with sulfuric acid and the flotation. Processing can significantly improve the quality of mineral raw materials, reduce transportation costs, reduce the processing difficulty, reduces the processing cost, and can realize the comprehensive utilization of mineral raw materials. Because of the world mineral resources become increasingly scarce, more and more use of low-grade and complex ore, ore and mineral processing therefore need more. At present, in addition to a small number of rich ore, metal and non - metal (including rough election and selection in the process of separation and scavenging the general case for roughing, scavenging, cleaning, suitable for flotation machine (ore flotation machine, magnetic separator) (dry magnetic separator, wet magnetic separator, magnetite ore dressing equipment). Mineral processing equipment. Ore by first after selecting, such as flotation, gravity separation and magnetic separation, part of the moisture content of gangue and surrounding rock have been selected, and the product is higher than that of the grade of raw ore, called rough concentrate, the general has not yet reached the concentrate quality requirements, this process is called a rough selection of service industry.
