在对安徽铜陵鸡冠山硫铁矿尾矿中黄铁矿风化产物组构特征研究的基础上,划分出代表不同风化程度的4种矿石组构型,并进而对不同组构型中硫和金属元素的含量、宫集系数、流失系数变化进行了研究。研究表明在风化过程中,As、Sb、Cu、Zn明显富集,其中As、Cu、Zn对环境的潜在危害较Sb大;Co、Ni、Bi明显流失或严重流失,对环境已经形成污染,其中Bi的污染程度较高。
Based on the study of the structural characteristics of pyrite weathering products in the tailings of Jiguanshan pyrite in Tongling, Anhui Province, four ore-formation configurations representing different degree of weathering are classified and the distributions of sulfur and metal The content of elements, the coefficient of palace set, the coefficient of loss were studied. The results show that during the weathering process, As, Sb, Cu and Zn are obviously enriched, among them As, Cu and Zn are more harmful to the environment than Sb; Co, Ni and Bi are obviously lost or seriously lost, polluting the environment, Among them, Bi is more polluted.
