This study focuses on the optimization of copper extraction from chalcopyrite concentrate using the Taguchi (L16) experimental design (DOE) method. The objective was to statistically optimize the leaching process of copper via ferric chloride in a hydrochloric acid medium. A series of experiments were conducted, and the experimental data underwent statistical analysis. Analysis of variance (ANOVA) revealed that the stirring rate was the most significant parameter affecting copper extraction, while the ferric ion concentration was the least effective. The chosen experimental parameters included a solid-to-liquid ratio of 2 g/500 mL, a ferric chloride concentration of 0.05 M, a leaching temperature of 30 °C, an acid concentration of 0.5 M, and a stirring speed of 400 rpm. The results indicated that under these optimized conditions, an approximate copper extraction rate of 89% from chalcopyrite was achieved. This research highlights the effectiveness of the Taguchi method for optimizing extraction processes, presenting a viable alternative to traditional pyrometallurgical methods in metal recovery from low-grade ores.
