Hebei Messi Biology Co., Ltd. stated that the raw materials for preparing silicon steel grade magnesium oxide are mainly magnesite (MgCO3), dolomite (CaCO3·MgCO3), magnesium-containing industrial byproducts, seawater or salt lake brine (MgCL2), etc. The production process can be divided into magnesium ore carbonization method and ammonium carbonate method with basic magnesium carbonate as intermediate, and […]

Hebei Messi Biology Co., Ltd. stated that with the rapid development of my country’s electromechanical industrialization, the entire market demand for silicon steel in special steel has put forward new requirements in terms of quality and quantity, and there is also a huge gap. Therefore, domestic silicon steel sheet production is in a period of

Hebei Messi Biology Co., Ltd. stated that with the development of the Congo (DRC) project, the hydrometallurgy of copper-cobalt mines has been vigorously developed in recent years. Compared with the traditional processes currently used, the technical advantages of many process flows applied to hydrometallurgy are unique. Many processes for purifying cobalt through precipitation operations have

Hebei Messi Biology Co., Ltd. stated that based on the first domestic silicon steel continuous annealing-coating experimental unit project developed by a steel plant, it conducted research and analysis on the selection of magnesium oxide for oriented silicon steel coating, developed a magnesium oxide coating system for oriented silicon steel, and studied the magnesium oxide

Hebei Messi Biology Co., Ltd. stated that magnesite is a magnesium carbonate with a chemical formula of magnesium carbonate (MgCO3), theoretical components: MgO: 47.81%, CO2: 52.19%, density of 2.9-3.1g/cm3, hardness of 3-5. Magnesite can be divided into crystalline and amorphous types according to its crystal state. Crystalline magnesite is rhombic hexahedron, columnar, plate-like, granular, dense,

Hebei Messi Biology Co., Ltd. stated that magnesium is an important element needed by the human body and plays an important role in regulating neuromuscular operation and blood sugar conversion. Therefore, a small amount of magnesium oxide needs to be added to many foods to supplement magnesium. The total magnesium content of a normal adult
