Aimed at solving some problems in geochemical exploration, this study employed the

thermomagnetic technique and chose some mining areas to carry out the technology application

research. With the Caijiaying Pb-Zn-Ag deposit in Hebei Province as a case study area, the authors

utilized the recent advances in search for concealed deposits and in recognizing the properties of

secondary anomaly. The research results show that the thermomagnetic technique is an effective ore-

prospecting method in coverage areas.
