摘要

Production of magnesium hydroxide comprises continuously supplying reactants to a system comprising stirred loop reactor and clarifier arranged so that hydroxide formation occurs in the central part of the reactor in the presence of a bed of magnesium hydroxide, product is discharged, practically solids-free solution is discharged via the clarifier and magnesium hydroxide separated in the clarifier is returned to the central part. Production of magnesium hydroxide comprises continuously supplying the reactants to a system comprising a stirred loop reactor and a clarifier arranged so that hydroxide formation occurs in the central part of the reactor in the presence of a bed of magnesium hydroxide with a solids content of 50-400 g/l, magnesium hydroxide product is discharged from the central part of the reactor, a practically solids-free reaction solution is discharged via the clarifier and magnesium hydroxide separated in the clarifier is returned to the central part of the reactor.
