In this study, the Mg(OH)2 slurry was made form ferro-nickel slag and then used for CO2 sequestration. The experi- ments were in the order as leaching step, precipitation, carbonation experiments. According to the leaching results, the optimal leaching conditions were H2SO4 concentration of 1 M and the temperature of 333 K. In the Mg(OH)2 manufacturing step, NaOH was added to increase the pH upto 8, the first precipitation was confirmed as Fe2O3. After removal the first precipitation,
