摘要
测定了采自贵州黔西南某富汞煤矿煤样中的汞含量,并对煤样进行了煤岩学研究和连续化学浸取研究。结果表明,汞绝大部分(平均81.9%)赋存于黄铁矿中,而黄铁矿又呈细粒星散分布于煤体中,因此通过选煤不能有效地去除此煤矿中的汞。
In this study,research is carried out on measuring the mercury contents in some coal samples collected from a certain mercury-rich coal mine in the southwest of Guizhou province.Coal petrology and sequential chemical extraction research is also carried out on these coal samples.Results show that majority mercury(81.9% in average) in coal is mainly found in pyrite,which are fine particles scattered in coal and it is difficult to effectively remove such mercury through washing.
