摘要 为了准确评价赣州矿山废石的产酸潜力,进行了净产酸试验、最大净产酸潜力试验和淋滤试验研究。研究结果表明:约一半矿山的废石样品具有酸化潜力,但净产酸量比较小,最大产酸量(H2SO4)仅为10 kg/t;赣州矿山废石含硫低,在酸雨作用下短期内不会全部酸化,但废石中的重金属元素均能溶出,其中Cd、Pb、Zn、Hg等重金属元素溶出量超标,污染周边环境。

Abstract: In order to accurately evaluate the acid production potential of chats in Ganzhou,the net acid production test,the maximum net acid production potential test and the leaching test were carried out.The research results showed that about half of chats samples had acidification potentials,but the net acid production was less,the maximum production of H2SO4 was only 10 kg/t.The chats in Ganzhou with low content of sulphur were not completely acidated in the short term,but the heavy metal elements in the chats could be all dissolved out,in which the dissolving-out quantity of Cd、Pb、Zn、Hg and other heavy metal elements were exceeding and would polluted surroundings.
