Abstract 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.
