【摘要】：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。
[Abstract]:Taking the sulfur slag in Zhenxiong County Yunnan Province as the research object the chemical composition of the slag samples in Zhenxiong slag distribution area was analyzed by analyzing the regional geological background and the characteristics of pyrite and sulfur slag in the area. The amount of slag in the region is estimated. By constructing a comprehensive evaluation index system of regional sulfur slag, a comprehensive evaluation of the sulfur slag resources in Zhenxiong, Yunnan Province was carried out. The results showed that the pyrite was widely distributed and had large reserves in the study area. The sulfur slag in the area is layered structure, imbricate structure and mixed accumulation, and the conditions of exploitation and utilization are better. Feanti, a valuable component in sulfur slag, has a good prospect of comprehensive utilization, but the harmful element is too high, so we should pay attention to the removal of S and P; The amount of slag in Heishu and Botou is larger, accounting for more than 80% of the total amount of cinder in Zhenxiong. The slag resources of Zhenxiong distribution areas are more balanced, and the comprehensive evaluation index of black tree and mother share is higher, which can be used as a typical area for the next regional slag demonstration study.
