| 摘 要： | 含砷金矿通常为难浸提金矿,因而选用经济、环保、有效的除砷预处理方法成为提高金回收提取效率的关键。综述了目前砷金矿预处理方法的优缺点和植物提取及砷转化的研究现状,结合超积累植物蜈蚣草在土壤砷污染植物修复方面的应用,提出了在砷金矿区种植砷超积累植物蜈蚣草来提取去除砷的设想,分析表明,植物预处理方法对于含砷较高的原矿、精矿,以及品位较低的含砷尾矿中的金回收具有广阔的应用前景。

| Abstract: | Leaching of gold from arsenic-containing gold ore is usually difficult,so pretreatment of arsenic-containing gold ore to remove arsenic is necessary to increase the leaching rate of gold.This paper reviews the advantages and disadvantages of existing pretreatment techniques of removing arsenic from arsenic-containing gold ore,the present situation of research on phytoextraction of arsenic and arsenic transformation in environment,and the application of hyper-accumulator pteris vittata L.in phytoremediation of arsenic-polluted soil.The authors advanced an idea to plant hyper-accumulator pteris vittata L.in arsenic-containing gold mine area so as to remove arsenic.The analysis showed that phyto-pretreatment technique has a certain prospect to improve the recovery of gold from high arsenic-containing gold ore,gold concentrate and gold tailings with low grade. |
