矿浆难免离子对铅锌硫化矿分离的影响研究进展

    Research Progress on the Effect of Inevitable Ions in Slurry on the Separation of Lead-Zinc Sulfide Ore

    • 摘要: 这是一篇矿物加工工程领域的论文。矿浆溶液中普遍存在一些难免离子,并且其中存在的难免离子对铅锌硫化矿的浮选分离有着重要影响。矿浆中难免离子主要来源于选厂用水、矿物自身溶解、活化剂或者抑制剂解离以及流体包裹体释放引入的原生离子和磨矿过程中引入的次生离子。本文对矿浆中引入的原生离子以及磨矿体系引入的次生难免离子对铅锌硫化矿浮选分离的影响进行了总结分析发现,不论是原生离子还是次生离子对铅锌硫化矿浮选行为的影响均较为明显,较多的学者针对这种现象进行了大量的研究。通过药剂调控以及改变磨矿环境等方法已经取得了较大的突破,为后续研究者提供了重要的研究思路。本文的关注点是将前人的研究成果与现场工艺紧密结合,在不影响工业经济情况下如何从源头消除难免离子,如何从现场工艺中降低难免离子对浮选指标的影响仍是未来研究的重要方向。

       

      Abstract: This is an article in the field of mineral processing engineering. Some unavoidable ions commonly present in the slurry solution have an important influence on the flotation separation of lead-zinc sulfide ore. The unavoidable ions in the slurry mainly come from the water used in the processing plant, the dissolution of minerals, the dissociation of activators or depressants, and the primary ions introduced by the release of fluid inclusions and the secondary ions introduced during the grinding process. This article summarizes and analyzes the effects on the flotation separation of lead-zinc sulfide ore which is caused by the primary ions introduced in the slurry and the secondary inevitable ions introduced in the grinding system. It is found that both primary ions and secondary ions have obvious effects on the flotation behavior of lead-zinc sulfide ore. And many scholars have done a lot of research on this phenomenon. In this paper, a great breakthrough has been made through the adjustment and control of reagents and changes in the grinding environment. At the same time, this article provides important research ideas for follow-up researchers. The focus of this article is how to integrate the previous research results with the field process significantly, how to eliminate inevitable ions from the source without affecting the industrial economy, The important direction of future research is still how to reduce the influence of inevitable ions on the flotation index from the field process.
