Hebei Messi Biology Co., Ltd. stated that the activated magnesium oxide cobalt extraction process is a method for efficiently recovering cobalt from low-grade cobalt ore. It adopts a combined process including leaching-iron removal-manganese removal-two-stage cobalt precipitation, supplemented by self-produced cobalt precipitation slag and two-in-one oxidant to obtain qualified cobalt hydroxide, realizing the utilization of low-grade […]

Hebei Messi Biology Co., Ltd. stated that the efficient cobalt extraction process with activated magnesium oxide involves a method for efficiently recovering cobalt from low-grade cobalt ore, which is suitable for application in the mining and metallurgy industry. Cobalt is an important material for manufacturing high-temperature resistant alloys, hard alloys, catalysts, new energy vehicle batteries

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 a metallurgical precipitation-grade active magnesium oxide for cobalt extraction and its preparation method and application, the active magnesium oxide prepared by this method has high purity and activity, and low calcium content and chlorine content. In addition, the tail water in the present invention is not discharged, and

Many of the magnesium oxides currently used in China are low-end products. Products such as calcium magnesium and light-burned powder are flooding the entire magnesium oxide market. Hebei Messi Biology Co., Ltd. stated that if magnesium oxide companies want to still occupy a place in the future development, they must change the current unhealthy state.

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,

Hebei Messi Biology Co., Ltd. stated that industrial oxalic acid and magnesium hydroxide were used as raw materials, and nano magnesium oxide was obtained by controlling the experimental conditions. The effects of calcination temperature, calcination time, reaction temperature, reaction time, oxalic acid concentration and surfactant concentration on the particle size of magnesium oxide products were

Under the current severe economic situation, Hebei Messi Biology Co., Ltd. fully utilizes the company’s innovation capabilities, starts early, and lays out early, continuously develops new products of medical and food-grade magnesium oxide, improves product quality, reduces product costs, and firmly occupies the main market share of domestic food-grade magnesium oxide. In order to effectively
