Experiments were conducted to evaluate domestic low-grade laterites and serpentinite waste as potential secondary sources of nickel magnesium assess leaching residues for carbon dioxide adsorption. Solids leached chemically using sulfuric acid, while bioreductive dissolution under anoxic conditions employed a consortium microorganisms dominated by Sulfobacillus. The efficiency laterite bioreduction was 26.81% Ni 63.92% Mg. In the case serpentinite, 20.54% 92.88% Mg extracted. chemical yielded 26.73% 61.37% in 16.20% 77.49% waste. Specific surface area analyzed during processes, showing systematic increase over time. Based on changes this parameter, mathematical description process proposed shrinking particle model (SPM). Except bioreduction, shown be two-stage controlled reaction. solid processed presence exhibited highest (267 m2/g) CO2 adsorption capacity 19.9 cm3/g.
