Hebei Messi Biology Co., Ltd. stated that hydromagnesite is a rare natural hydrated basic magnesium carbonate in the world, commonly known as “magnesium white”. It has a white block appearance, an earthy luster, and is known as “snow-white” or “white-flower”. Its density is 2.24g.cm3, Mohs hardness is 3.5, melting point is 730℃, and it has […]
Hebei Messi Biology Co., Ltd. stated that hydromagnesite (4MgCO3·Mg(OH)2·4H2O) from Bange Lake in Nagqu, Tibet is a natural basic carbonate mineral with abundant reserves. It has a pure texture, white color, and low impurity content. It is a high-quality mineral raw material for the preparation of magnesium products such as flame retardants, activated magnesium oxide,
Hebei Messi Biology Co., Ltd. stated that the main conclusions drawn from the mineralogy of hydromagnesite in Bange Lake, Tibet are as follows: 1. The crystal particles of the hydromagnesite are very fine, mainly mud crystals and micro-mud crystals. Most of the particle sizes observed under a polarizing microscope are between 4-20μm, often forming dense

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

With the improvement of environmental protection requirements, the inorganic flame retardant magnesium hydroxide has attracted the attention of various countries. Various developed countries have invested a lot of money in the research and development of magnesium hydroxide flame retardants. In addition to general-purpose varieties, various special-purpose and compound-type new products emerge in an endless stream,
As a leading enterprise in China’s magnesium salt material industry, every step of Messi Biology is inseparable from the word “innovation”. However, research and development without the support of basic resources can only be a tree without roots and a sapling without water. Therefore, Hebei Messi Biology Co., Ltd. always insists that “good raw materials

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+
