The method of partial metal extraction (PME) is based on the isolation of electromobile forms of chemical elements from soils. Based on the results of observations by the PEM method are determined by the site with anomalous concentration of EPFN chemical elements, which are judged on the presence in the area of ore objects.
The method of partial extraction of metals is applied in the search for deep deposits in two variants: extraction under the action of an active electric field (PEM) and diffusive extraction of metals under the action of electrochemical potentials (PEM-MDI).
