A sulfate-containing Friedel’s salt (FS) was synthesized and applied as an intensifying adsorbent in combination with alunite processing residue (alunite mud, AM) to improve silicon removal efficiency while reducing reagent consumption. Adsorption experiments were performed at temperatures ranging from 50 to 90°C, reaction times of 2–5 h, and varying adsorbent dosages. Under the optimized conditions of 50°C, 2 h, and FS dosage of 15 + 5 g, the SiO<sub>2</sub> concentration decreased from 0.327 to 0.0175 g/L, corresponding to a silicon modulus of 5034.2. The Taguchi L9 orthogonal array design was employed to statistically evaluate and optimize the effects of temperature, time, and FS dosage on desilication performance. The results revealed that FS dosage was the most influential parameter governing silicon removal, followed by temperature, whereas reaction time exhibited a comparatively minor effect. Analysis of variance (ANOVA) confirmed the statistical significance of all investigated factors (<i>P</i> &lt; 0.05), with FS dosage showing the highest contribution to variance (Seq SS = 2,735,121). Residual analyses demonstrated that the developed Taguchi model satisfies the principal statistical assumptions, confirming the reliability and robustness of the optimization.
