To increase the technological characteristics of processing of the ores of the Urup deposit, the flow chart of stream flotation
and a column flotation machine are applied to separate a rough concentrate in a second flotation stream. A vapor-air mixture
with the addition of a foam former and oleic acid fed into the column through a pneumohydraulic aerator of the diffuser-confusor
type is used as the gas phase during the column flotation. 相似文献

Based on the laboratory studies of ore concentration and the statistical processing of the characteristics of operating a
lead-zinc plant, it is established that obtaining a high-quality commercial lead concentrate is possible only after the additional
reduction of the crude concentrate. It is proven that the characteristics of flotation increase as the content of metals in
the starting ore increases. The revealed dependences are used in development of the technology of zinc removal from the lead
concentrate to improve the characteristics of ore dressing. The idea of this technology is that the batch is prepared from
the concentrate and the ore; the charge is ground in the ore mill and concentrated by the schematic of direct selective flotation.
An increase in the quality of the lead concentrate is reached due to the opening of aggregates of galenite with sphalerite
and pyrite. The increase in the characteristics of ore concentration is explained by an increase in the content of metals
in feeding the flotation and by a decrease of the ratio of the zinc content to the lead- the zinc module. The commercial characteristics
obtained as a result of industrial tests of the technology of zinc removal from the lead concentrate due to repeated flotation
with the starting ore confirmed the high efficiency of the developed technology. 相似文献

浮选是矿物加工过程中的重要环节,在浮选过程中需要加入各种浮选药剂将有用矿物从矿浆中分离.多数浮选药剂成分复杂、难以降解,使浮选废水中残留着大量的浮选药剂.普通废水处理工艺对残留浮选药剂去除效果较差,难以达标排放,高级氧化技术作为一种高效的废水处理手段,对残留浮选药剂降解有着良好的效果.文章简要介绍了选矿药剂概念和选矿废水的来源、成分、特点及其危害,对国内外高级氧化技术降解选矿废水的应用研究进行论述;探讨分析Fenton氧化、光化学氧化、声化学氧化、臭氧氧化等高级氧化技术对选矿废水的降解机理,并对高级氧化技术降解选矿废水的应用前景进行展望. 相似文献
