Practically and theoretically important are studies aimed at creating new methods for purifying copper electrolyte with the removal of such a dangerous impurity as arsenic in a form suitable for the intended use. Using probabilistic-deterministic planning of the experiment, the course of chemical reactions in manganese-and arsenic-containing systems, the directions of reactions and the stability of their constituent phases were studied. Based on experimental data and thermodynamic analysis, the probable behavior of chemical elements and their compounds, the limits of potential and pH, within which a given compound of an element must be stable, are determined. X-ray diffraction identified the formation of manganese arsenate (Mn3 (AsO4)2·4H2 O) in deposits formed during the extraction of arsenic from a copper electrolyte with manganese (IV) oxide.
