Description

一种用于回收尾矿中硫化矿捕收剂的制备方法A preparation method for recovering sulfide ore collector in tailings

一、技术领域1. Technical field

本发明涉及一种硫化矿选浮捕收剂,具体是一种用于回收尾矿中硫化矿捕收剂的制备方法,适用于长期堆存尾矿中部分表面氧化的硫化矿的选浮捕收剂。The invention relates to a sulfide ore separation and flotation collector, in particular to a preparation method for recovering sulfide ore collectors in tailings, which is suitable for the separation, flotation and capture of partially oxidized sulfide ores in tailings for long-term storage Receiver.

二、背景技术2. Background technology

在一些复杂多金属硫化矿的尾矿库中,常含有一定价值的硫化矿物,这些硫化矿物是在当时的选矿过程中,由于要考虑多金属的综合回收,再加上以前选矿技术水平的限制,未能及时回收,被当成尾矿堆于尾矿库中。由于长时间堆存,这些硫化矿表面或多或少形成氧化膜,如果再次回收这部分硫化矿物则比较难。目前国内外对这些硫化矿一般都是采用硫酸或硫酸铜先活化,然后加长碳链黄药进行浮选捕收,硫化矿的浮选回收率在60~65%之间,捕收效果不甚理想,特别是对于表面氧化比较严重的矿物,必须加大量的硫酸或硫酸铜对硫化矿物进行活化,然后再进行捕收。尽管如此,还是有部分硫化矿物未能回收,达不到二次资源利用的目的。如何尽量回收这部分硫化矿物,提高其回收率目前则是选矿界关注的问题。In the tailing pools of some complex polymetallic sulfide ores, there are often sulfide minerals of certain value. These sulfide minerals were produced during the beneficiation process at that time, due to the consideration of the comprehensive recovery of polymetallic and the limitation of the previous beneficiation technology level , failed to be recovered in time, and were piled up in the tailings pond as tailings. Due to the long-term stockpiling, the surface of these sulfide ores has more or less formed an oxide film, and it is more difficult to recover this part of the sulfide ores. At present, these sulfide ores are generally activated by sulfuric acid or copper sulfate at home and abroad, and then the carbon chain lengthening xanthate is used for flotation collection. The flotation recovery rate of sulfide ores is between 60% and 65%, and the collection effect is not very good. Ideally, especially for minerals with serious surface oxidation, it is necessary to add a large amount of sulfuric acid or copper sulfate to activate the sulfide minerals, and then collect them. Nevertheless, there are still some sulfide minerals that cannot be recovered, failing to achieve the purpose of secondary resource utilization. How to recover this part of sulfide minerals as much as possible and improve its recovery rate is currently a concern of the mineral processing industry.
