The entire cobalt industry chain involves four parts: ore mining, cobalt concentrate/intermediate supply, refined cobalt supply and downstream terminal applications. The upstream is the mining of copper-nickel associated ores of cobalt mines, the midstream is the smelting and processing of cobalt mines, and the downstream is mainly consumed by batteries. As the largest producer of

Hebei Messi Biology Co., Ltd. stated that magnesium oxide is a magnesium oxide with a chemical formula of MgO and a typical sodium chloride structure, with magnesium atoms and oxygen atoms arranged in sequence. Magnesium oxide is a high-functional fine inorganic material that can be widely used in catalysis, electronics, ceramics and other fields. Magnesium

Glassy carbon electrodes made from nano magnesium oxide have many characteristics, such as good battery stability, high conductivity, high purity, no gas in the electrode, easy surface regeneration, small hydrogen and oxygen overpotential, and low price. Below, Hebei Messi Biology Co., Ltd. briefly introduces the preparation process of adding nano magnesium oxide to lithium batteries.

According to the survey of Hebei Messi Biology Co., Ltd., although the application range of high-purity magnesium oxide is wide, the application demand is relatively small. The current domestic high-purity magnesium oxide market demand is about 52,000 tons. In terms of production, my country’s high-purity magnesium oxide production technology cannot meet the application needs, and

Hebei Messi Biology Co., Ltd. stated that a preparation method of silicon steel grade magnesium oxide coating specially used for oriented silicon steel sheet includes the following process steps: select natural cryptocrystalline magnesite to produce light-burned magnesium oxide powder; digest the light-burned magnesium oxide, neutralize and decalcify with acid and alkali, react at a temperature

Magnesium oxide was used to modify the commonly used carrier γ-Al2O3 for sulfur-resistant shift catalysts, and the pressurized “original particle size” evaluation device and analytical testing methods such as XRD and SEM were used to evaluate CoO-MoO3/γ-Al2O3+MgO sulfur-resistant shift catalysts. The catalyst was studied. The results show that adding an appropriate amount of magnesium oxide

At present, the cobalt product of cobalt salt plants is crude cobalt carbonate, which is precipitated with sodium carbonate, and the liquid is directly discharged after precipitation. The defect of this process is that there is a large amount of sodium sulfate in the discharged waste liquid. The wastewater containing sodium sulfate is not easy
