AB Acid mine drainage (AMD) is a process resulting from mining activity, which has a potentialdegrading effect on metallic materials used in machinery and structural installations, mainly carbonsteel composites. This work shows how steel is affected and degraded by AMD, as well as thephysicochemical changes that occur in the solvent as a consequence of the metal corrosion process.For this purpose, thirty specimens were immersed in AMD for thirty weeks and were removed onceper week, observing the changes that had occurred both in the metal and in the solvent to whichit was exposed. The results show a material degradation with a loss of weight and alterations inthe acid drainage with an increase in pH, total dissolved solids (TDS) and modifications in the restof the solvent characteristics. The data from the measurements of the plates under study, togetherwith the physicochemical data of the resulting reagent solution, were integrated into matrices forsubsequent graphical–statistical processing using Statgraphics Centurion software, a powerful toolfor exploratory data analysis, statistical summary, analysis of variance, statistical control, multivariateanalysis, time series, etc., and which allows the different variables studied to be classified intocategories or proximity ratios
