The study of the kinetic features of the dissolution of chromium is relevant in connection with its wide application in steels and alloys, strength and corrosion-resistant coatings, in electronic engineering and many other industries. In connection with the depletion and decrease in the reserves of chromium-containing ores, the creation of new highly efficient technologies for their processing is of paramount importance. Along with topical issues of optimization of technologies for chemical etching, leaching and enrichment of chromium-containing ores, the development of combined chemical-electrochemical methods, the development of the theory and practice of electrochemical methods of processing mineral raw materials are promising. The paper presents the results of studying the features of the anodic behavior of chromium in an acidic environment. An aqueous solution of sulfuric acid was used as a working solution. The dependence of the kinetics of dissolution of the anodic dissolution of chromium on the acidity of the electrolyte was established by the potentiodynamic method. Based on the analysis of experimental and thermodynamic data, it was concluded that the process proceeded in stages with the formation of chromium hydroxo complexes, and the mechanism of its anodic dissolution. The data obtained expand the understanding of the electrochemical behavior of chromium and can be taken into account when developing regimes for leaching chromiumcontaining ores and processes associated with the dissolution of chromium in acidic media.
