Test data indicate that the artificial electric field can activate and change the binding modes of occurrence of elements in the soil. On the one hand, It can bring about decomposition of a great number of complex anions and other stable or sub-stable forms of elements, and on the other hand, it can make anions and cations move to the extraction electrode, and can accelerate ionic movement, as can be seen from the comparison of the artificial electric field and the extracted liquid in the element-collectors (ECs), no matter whether the artificial electric field is close to the ECs or not and how different the modes of occurrence of elements in the samples from the soil are. In fact, it is quite impossible for the artificial electric field to extract directly the metal ions from the ore body at depth.
