This study introduces a cementation system employing iron screens positioned within a mechanically stirred batch reactor for efficient copper extraction from wastewater. Systematic experimental investigations examined the influence of four operational parameters: initial copper concentration (0.01–0.03 M), agitation speed (100–800 rpm), reaction duration (up to 50 minutes), and number of iron screens (3–7). Results demonstrated that copper removal efficiency reached 82–88% under optimized conditions, with the process governed primarily by external mass transfer rather than surface reaction kinetics. Response Surface Methodology yielded a highly predictive quadratic model with good agreement between experimental and predicted values of copper removal (R² = 0.9846). Multi-objective optimization identified optimal operating parameters: 0.0295 M initial concentration, 757 rpm agitation intensity, 47.4 minutes reaction time, and three iron screens, achieving 87.57% copper recovery. The proposed system offers distinct advantages including operational simplicity, direct recovery of metallic copper, minimal chemical consumption, and straightforward industrial scalability. This work presents a sustainable, cost-effective solution for copper-bearing wastewater treatment that simultaneously addresses environmental protection and resource recovery imperatives.
