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. […]

Hebei Messi Biology Co., Ltd. stated that cobalt ores rarely exist alone in nature. They are mainly associated with nickel ores, copper ores, pyrite and arsenic deposits, and the content is relatively low, so it is relatively difficult to extract. Cobalt ore resources mainly include nickel-cobalt sulfide ores and oxide ores, copper-cobalt ores, arsenic-cobalt ores,
