云南镇雄区域硫磺矿渣资源特征及评价

Characteristics and Assessment of Sulfur Slag in Zhenxiong,Yunnan

以云南镇雄县区域的硫磺矿渣为研究对象,通过分析区域地质背景、区内硫铁矿及硫磺矿渣的特征,对镇雄矿渣分布区的矿渣样品进行化学组分分析,并对区域矿渣量进行了估算;通过构建区域硫磺矿渣综合评价指标体系,对云南镇雄硫磺矿渣资源进行了综合评价。结果表明:研究区内硫铁矿分布广泛,储量大,区内的硫磺矿渣呈层状构造、叠瓦状构造和混杂堆积,开发利用条件较好;硫磺矿渣中有价成分Fe、Ti具有较好的综合利用前景,但有害元素S、P过高,应关注除S、除P;黑树和坡头的矿渣量较大,占整个镇雄矿渣量的80%以上;镇雄各分布区矿渣资源较为平衡,其中黑树和母享的综合评价指数较高,可以作为下一步区域矿渣示范研究的典型区域。

This paper selected sulfur slag in Zhenxiong,Yunnan as the research object. Through the analysis of regional geological background,the characteristics of sulfur and sulfur slag,it analyzed the chemical composition of sulfur slag samples.And then,it estimated the amount of sulfur slag in this region.Then,it made the comprehensive assessment by building the regional sulfur slag comprehensive evaluation index system.The results indicated that sulfur ore was widely distributed and had huge reserves.The structure of sulfur slag in research areas was layer structure,imbricate structure or mixed accumulation,which was piled up in the earth＇s surface. Adding the convenient traffic,sulfur slag could be developed and used more easily. The valuable components such as Fe and Ti in mixed slag had good comprehensive utilization prospect,but the harmful elements such as S and P,whose contents were too high,should be attention to get rid of them. The amount of slag in Heishu and Potou is larger,which is more than80%of the whole.The slag resources distribution of Zhenxiong is relatively balanced. The comprehensive evaluation index of Heishu and Muxiang is higher,so they could be used as the typical area of the demonstration research.
