摘　　要：对某地锰银精矿及冶炼半成品———粗银粉,采用湿法溶样后,直接采用硫氰酸钾容量法测定Ag,对w(Ag)为0.22%～70.96%的样品,测定结果与原子吸收法以及火试金容量法结果相符。After decomposition of Mn-Ag concentrates and raw Ag powder samples with HCl-HNO_(3)-H_(2)SO_(4), Ag in the sample solutions was determined by KSCN-volumetry. The analytical results obtained are in agreement with those provided by AAS or fire assay-volumetry for samples with w(Ag)=0.22%～70.96%.
