Geo-electrochemical extraction effectiveness and conditions test- Taking semi-arid grasslands aeolian shallow overburden areas as an example

Geo?electrochemical extraction is an effective method in mineral exploration for overburden covers, the principle of which is to extract near?surface materials selectively artificial electric field. The exploration method provides prospecting information by studying the electrical extracted element combination、content distribution and anomaly characteristic. Applying this technique to the Luokedun deposit in Inner Mongolia, we proved the effectiveness of geo?electrochemical exploration for aeolian shallow overburden areas. Compa?ring different extraction time and density carriers, we conclude that the extraction time of 24h and high?density ploolyform carrier mate?rial is the best choice for geo?electrochemical exploration in this area.
