Geo-electrochemical extraction technology test and the prospecting prediction in cold plateau area

Abstract: To better explore the best working technical conditions of geo-electrochemical extraction techniques in the cold plateau area, the authors chose 7 line sections of the engineering-controlled Gardaban copper polymetallic deposit in Qinghai for the contrastive experimental study with geo-electrochemical extraction technology, and designed a set of suitable geo-electrochemical extraction technologies for the cold plateau area. Through comparative tests, the authors determined the technical indicators: the extraction time is forty-eight hours, the service voltage is 9 V, the concentration and dosage of extracting solution are 15% and 1000 ml respectively, the pole pitch of extraction is 1 m, and the material of extraction is foam plastic. The optimal working technical conditions were adopted, and the prognostic work for concealed orebodies was conducted in the unknown area in the southeast part of the ore district. As a result, four favorable ore-prospecging targets were delineated, which can play the guiding role in the further ore-prospecting work.
