1. Brine-lime method Preliminary purified and refined brine and lime milk made from digested and deslagging lime are precipitated in a sedimentation tank, and flocculants are added to the obtained slurry. After sufficient mixing, the slurry is separated in a sedimentation tank, and then filtered, washed, dried, and crushed to obtain the finished magnesium oxide. […]
