Abstract:

In order to discover the mechanism and anomaly origin of geoelectrochemical extraction, an experimental study has already been conducted in Dagenlong Tungsten deposit in Hunan. We take soil samples by interval of 20 m, and implement the geoelectrochemical extraction under the working conditions of the following three: the extracting time is 24 hours, the dose of HNO3 is 1 000 mL, and the distance between two electrodes is 50 cm. The result shows that the variation of metal element content is insignificant in soil after extracting, and the extracted metal elements are proportional to the whole metal in the soil. The morphology comparison of anomaly between the geoelectrochemical extraction and the secondary halo shows that Ni and Co is clear, W is less, and Cr has no anomaly. The characteristics of anomaly mainly depend on the content proportion of element which is active in soil. Comprehensive analysis shows that the anomalies of geoelectrochemical extraction related to the relative position of the ore body. It is easy to form anomaly at downhill position, and distance too close to native ore body have obvious interference to anomaly. In this ore deposit area, the higher weathering degree, the better Co,Ni anomaly of geoelectrochemical extraction. The anomaly width of geoelectrochemical extraction is smaller than secondary halo.

Key words: geoelectrochemical extraction, tungsten deposit, Dagenlong in Hunan Province, characteristics of anomalies
