This research work was composed of experimental tests, which were conducted in the laboratory of the gold ore leaching plant with high copper content, which means the same operating conditions. This study consisted in characterizing mineralogically and analyzing chemically the metallic concentration of Au, Ag, Cu, Ni, Zn of the processed ore, which are the main elements that contribute to the formation of CNWAD. The metallic concentration of Au, Cu were analyzed chemically of the liquid and solid part of the pulp before and after the elimination of CNWAD according to the experimental design methodology. The analyzed concentrations of CNWAD and Cu in the liquid part of the pulp were used after the elimination of CNWAD for the assessment of the correlation by means of a linear regression, obtaining a degree of correlation of 0.983703, 0.972912 and 0.936632. In the first stage of the design of experiments, the factorial design was applied to evaluate the variables: Stirring velocity, hydrogen peroxide excess factor and pH on the degree of elimination of CNWAD. Where the variable factor of excess hydrogen peroxide was the most significant followed by pH. In the second stage of the design of experiments, the mathematical model of the degree of elimination of CNWAD was established, determining the following model of first degree to natural scale.
