| 摘 要： | 近年来，人们对金的需求不断增长，而砂金矿资源日益枯竭，人们已把目光转向由伴生矿和低品位矿中金的开采。目前，从低品位金矿中提炼、富集金的方法虽然很多，但用萃淋树脂对金矿中作分离、富集提取手段的报道还不多见，本文用Ｐ２０４－萃淋树脂制成的交换柱，以ＮＨ４ＳＣＮ（１０％）／ＮＨ４Ｃｌ（１０％）（１＋１ｖ／ｖ）作为洗脱剂，对低品位贫矿中微量的金作了分离、富集提取的研究，结果可使金的浓度富集达１０＾３倍，同

| Abstract: | At present, the methods of extracting gold in ore are developed. But to extract gold in oreby levextrel resin is not widely reported . By using P204 - levextrel resin as fixed phase and NH4SCN(10% ) /NH4Cl (10% ) as eluant to extract gold in ore is described in this paper . The recoveries ofgold in ore have been assayed and the range was found to be 0. 902 - 0. 975. The results are satisfied. |
