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 method for gold and silver exploration was proposed. This method uses a mixed leaching agent to chelate the collected geochemical secondary halo samples by chelating adsorbents. Partial extraction of gold, silver content, the use of liquid-bead extraction colorimetric determination of gold and silver, so as to achieve the chemical exploration directly to find gold, silver purposes. This method overcomes the “grain effect” in the work of geophysical prospecting. The device is simple and easy to operate.
