Preparation of magnesium hydroxide slurry with cationic surfactant

Leave a Comment / Magnesium Hydroxide /

Hebei Messi Biology Co., Ltd. stated that after simple purification of brine, lime as a precipitant is added to produce magnesium hydroxide precipitation. The slurry produced by the reaction must be concentrated by precipitation and filtration to wash away excess chloride to make slurry with various solid contents. When preparing the slurry, the stability of
