Several artisanal and small-scale gold mining (ASGM) sites in Colombia were located and sampled. At each ASGM site, tailings samples were collected and analyzed. Establishing rapport with mining stakeholders and analyzing the samples allowed our team to draw conclusions about the inefficiency of mercury-use in gold extraction and the superior efficiency of centrifugal and gravimetric methods for reprocessing the mining residues produced by artisanal gold miners.

哥伦比亚安蒂奥基亚安第斯山脉手工和小规模金矿开采尾矿中的废物管理和汞去除

哥伦比亚的几个手工和小规模金矿 (ASGM) 地点被定位和取样。在每个 ASGM 地点，都收集并分析了尾矿样本。与采矿业利益相关者建立融洽关系并分析样本，使我们的团队能够得出结论，关于在黄金提取中使用汞的效率低下，以及离心和重量法对手工黄金矿工产生的采矿残渣进行再处理的优越效率。
