铜铅锌多金属硫化矿浮选分离研究探析本文首先介绍了铜铅锌等金属的性质、作用和资源概况,并阐述了铜铅锌多金属硫化矿分离难的原因,然后重点分析了目前我国在开采铜铅锌多金属硫化矿中常用技术之一的“浮选分离”技术,对其概念、特点、工艺流程和作用进行了具体说明,期待能为矿产开发人员提供一点微不足道的借鉴方法。
标签:铜铅锌多金属硫化矿;浮选分离一、引言众所周知,金属矿产资源是一种不可再生的资源,我国虽然地大物博,矿产资源较为丰富,但是我国矿产资源有先天的缺陷或者说特性,比如品位低、有用矿物嵌布粒度细以及矿物共生复杂等,这就使得在开采矿产时,需要经过很多道工艺和流程,结合先进技术对矿产的各种金属元素进行分离,极其费时费力。
经验和历史都证明,矿物浮选分离技术是先进的选矿方法之一,在处理低品位和复杂难选的矿产时具有其他技术和方法不可比拟的优势。
二、铜铅锌多金属硫化矿的特点铜铅锌多金属硫化矿大多形成于热液型或卡矽岩型矿床中,砂卡岩型矿床矿石以中等品位为主,热液型矿床矿石的品位较低,但热液型矿床工业意义更大,绝大多数的铜铅锌多金属硫化矿石均开釆自深成热液型及中、低温热液型矿床。
该类矿石的主要铜矿物有黄铜矿、斑铜矿、辉铜矿,铅矿物主要为方铅矿,锌矿物主要为闪锌矿、铁闪锌矿,主要的铁矿物为黄铁矿、磁黄铁矿,矿石中还可能含有部分氧化矿物如孔雀石、蓝铜矿、白铅矿等。
铜铅锌多金属硫化矿除含铜、铅、锌等金属元素外,还常伴生镉、铟、金、银,有时矿石还含有硒、钽等稀散元素。
因此,对该类矿石进行综合回收具有巨大的经济价值。
三、铜铅锌多金属硫化矿浮选分离难的原因铜铅锌多金属硫化矿的矿物组成通常较为复杂,难以分离,其原因主要有几点:(1)高温热液型的矿石中,铜矿物往往呈細粒或微细粒浸染状态存在于闪锌矿中。
这矿石中有用矿物致密共生,结晶粒度非常细小,导致三种矿物难以单体解离,分离困难。
即使通过磨矿使三者单体解离,但矿物粒度过细,浮游速度变慢,同时矿粒的比表面积增大,使铜矿物等颗粒的可溶性增加,矿浆中难免离子浓度增大,导致分离效果变差。
采矿工程M ining engineering 铜矿石提高回收率的选矿新工艺探究杨 宇(紫金(厦门)工程设计有限公司,福建 厦门 361009)摘 要:我国的铜矿资源虽然十分丰富,但人均占有量较低,并且我国的铜矿资源中还有很多低品位、复杂难选的铜矿资源,在当前铜矿资源日益枯竭的背景下,如何对这些特殊的铜矿资源实现进一步的开发利用有着非常重要的现实意义。
这就需要相应的开发企业能够使用更为先进、合理的选矿技术,同时进一步提升铜矿石中铜的回收效率,这样不仅有利于提高企业的经济效益,同时还能提高铜矿资源的利用效率,避免了一些不必要的浪费现象,有助于促进我国国民经济的进一步发展。
本文以某铜矿为例,在对该铜矿的矿石性质进行分析的基础上,对当前使用比较广泛的几种选矿方法进行了对比分析,并通过相应的试验分析得出了新工艺的应用价值,以期对促进我国铜矿事业的更好发展有所裨益。

Under the background of increasingly exhausted copper resources, how to further develop and utilize these special copper resources has very important practical significance. This requires the corresponding development enterprises to be able to use more advanced and reasonable beneficiation technology, and further improve the copper recovery efficiency in copper ore, which is not only conducive to improving the economic benefits of enterprises, but also improving the utilization efficiency of copper resources, avoiding some unnecessary waste phenomenon, and promoting the further development of China's national economy. Taking a copper mine as an example, based on the analysis of the ore properties of the copper mine, this paper makes a comparative analysis of several mineral processing methods widely used at present, and obtains the application value of the new technology through the corresponding experimental analysis, so as to promote the better development of copper industry in China.Keywords: copper ore; recovery; new mineral processing technology某铜矿随着开采时间的不断推移以及开采力度的不断增大,使得了当前该铜矿也由最初的露天开采转变成了地下开采。
