The article discusses the results of studies on the electrochemical leaching of metals with the addition of a surfactant under the influence of infra-low-frequency current. Mathematical models of the dependence of leaching indicators at various numerical values of density and specially taken from the research range from the maximum allowable to standard production values of the DC reverse frequency and mathematical models characterizing the direct dependence of the leaching indicators on the density and duration of DC pulses are presented. The obtained results of the analysis of the effectiveness of the proposed method are presented in the form of tabular data on the leaching of ore under the influence of a reversible direct current, which allows assessing the prospects for processing secondary raw materials.
