摘　　要：提出了一种化探找金、银的新方法,该法采用一种混合浸取剂,以螯合吸附剂对采集到的化探次生晕样品进行偏提取。对偏提取的金、银含量,利用液珠萃取比色法进行金、银含量测定,从而达到化探直接找金、银的目的。该法克服了化探找金工作中的"粒金效应"。该设备简单、易操作。A new prospecting method for gold and silver is put forward in this paper. A mixed extraction agent is adopted, partial extraction of geochemical secondary halo samples is performed with chelatometric absorbent, and liquid bead extraction colorimetry is used to determine gold and silver content. In this way, the aim of direct prospecting for gold and silver can be achieved. This technique is characterized by simple and rapid operation, simple device, and can overcome the 'grain gold effect' in geochemical gold exploration. 
