A novel method of using waste ,calcium carbide, to mineralize carbon dioxide by electrolytic aluminium waste gas was proposed. In this research, a three stage reactor with venturi tubes was designed and fabricated. Effects of various gas rates, solution rate, initial concentration of solution and carbon dioxide on bubble behavior were investigated.
