Abstract
Disclosed is a process for producing and then rapidly recovering magnesium hydroxide from an aqueous liquid containing magnesium ion. The magnesium hydroxide is produced by treating the aqueous liquid with lime. The particles of magnesium hydroxide are then recovered from the liquid by causing rapid agglomeration and separation of the magnesium hydroxide particles.
