We used the polyurethane foam plastic which was puried and had strong adsorption ability as the extractor��with 1 L pure water as extracting solution and using low voltage (9V) dipole geoelectro- chemical extrac- tion to carry out feasibility research to search for hidden ores in Wushan Copper Mine�� The results show clear Cu�� Pb and Zn geoelectro- chemical anomaly appear on the top of concealed copper ore body�� The positions of anomaly are always identical with known mineralized body�� Experimental results show that the method can indicate deep ore body clearly in this region��
