Hydromagnesite

In addition to the main component MgCO3, magnesite ore often contains impurities such as CaCO3, FeCO3, MnCO3, Al2O3 and SiO2. In order to remove harmful impurities and improve the grade of ore, the current industrial beneficiation methods of magnesite mainly include flotation, roasting and chemical treatment. Flotation Flotation is a method that uses the differences […]

Magnesite is a magnesium carbonate, its chemical formula is magnesium carbonate (MgCO3), theoretical composition: MgO47.81%, CO252.19%, density 2.9-3.1g/cm3, hardness 3-5. Magnesite can be divided into two types: crystalline and amorphous according to its crystallization state. Crystalline magnesite is rhombohexahedral, columnar, plate-like, granular, dense, soil-like and fibrous, etc. It often contains calcium and manganese isomorphs. Fe2+

Natural hydromagnesite (hydromagnesite compound flame retardant) Hydromagnesite is a new type of high temperature resistant flame retardant, which can release water and CO2 successively under the action of heat. These decomposition and release processes can absorb a lot of heat, thereby reducing the flame retardant. The temperature of the flame on the surface of the

As a common hydrated magnesium-rich carbonate mineral, hydromagnesite [Mg5(CO3)4(OH)2·4H2O] can be used as a high-quality mineral-type flame-retardant filler in the field of polymer flame-retardant. Studies have shown that hydromagnesite mainly occurs in carbonate-type saline lakes and Quaternary lacustrine strata, and was also found in the lacustrine deposits of Jezero Crater on Mars, and the Mg/Ca

Hebei Messi Biology Co., Ltd. stated that hydromagnesite is a newly developed high-magnesium ore, which can be used as a flame-retardant filler. Hydromagnesite is a natural basic magnesium carbonate. The ore has high magnesium content, white quality and low impurity content. It is a high-quality magnesium-containing non-metallic mineral material and a high-quality raw material for
