<p>Disclosed are a manufacturing method of magnesium hydroxide slurry for desulfurization, and an apparatus therefor. Provided is a manufacturing method of magnesium hydroxide slurry for desulfurization, which comprises a process of producing first slurry, in which brucite powder containing magnesium hydroxide (Mg(OH)2), silicon dioxide (SiO2) and calcium oxide (CaO) is mixed with water at a predetermined ratio; a process for producing second slurry, in which silicon dioxide (SiO2) and calcium oxide (CaO) having a larger particle size than a predetermined particle size included in the brucite powder are filtered from particles that the first slurry is crushed; and a process of producing third slurry, in which silicon dioxide (SiO2) and calcium oxide (CaO) having a smaller particle size than the predetermined particle size are filtered from the second slurry.</p> |
