Resource mining, deep processing technology and wide application of brucite, hydromagnesite and orthorhombic marble
Brucite, hydromagnesite and orthorhombic magnesia are all carbonate minerals containing magnesium. They are widely used in resource development, material science and many industrial fields. The following is a brief overview of the processing and application of these three mineral resources:
Brucite (Mg(OH)_2)
Resources and Distribution: Brucite is often found in low-temperature hydrothermal alteration zones of serpentinite or dolomite. The Kuandian area of Liaoning Province, China has high-quality brucite deposits close to theoretical quality. In addition, Canada, Türkiye, Greece and other places also have brucite resources. Processing: The processing of brucite mainly involves crushing, grinding and possibly chemical treatment to obtain the required particle size and purity for use in different applications. Application: Due to its good flame retardancy, brucite is widely used in the manufacture of magnesium flame retardants; at the same time, it is also used as a neutralizer, heavy metal ion remover, magnesium fertilizer, feed additive, etc. It is used as an environmentally friendly flame retardant filler in plastics, rubber, paint and other industries. Hydromagnesite (Hydromagnesite, Mg_5(CO_3)_4(OH)_2·4H_2O)
Resources and characteristics: Hydromagnesite is a naturally produced magnesium carbonate hydrate with a wide global distribution. Tibet is an important producing area in China, and this mineral has unique mineralogical properties and thermal decomposition properties. Processing and modification: Hydromagnesite can be modified through physical or chemical methods to improve its performance in specific applications, such as heat treatment to improve its application performance in building materials or chemical products. Application: Modified hydromagnesite can be used as reinforced filler for plastics and rubber, as a raw material for environmentally friendly building materials, and as a soil conditioner in agriculture. Dolomite, CaMg(CO_3)_2
Resources and distribution: Orthorhombic marble is a common carbonate mineral, widely distributed around the world, and its resources are relatively abundant. Processing: The processing of orthorhombic marble includes crushing, screening and grinding, and sometimes calcination is required to change its physical and chemical properties to meet specific application requirements. Application: Orthorhombic marble is mainly used in traditional industries such as steel, glass, and cement, as a flux for steelmaking, a flux for glassmaking, and as a raw material for decorative stone and cement in the construction industry. In addition, it is also used in agricultural soil conditioning and environmental governance. These three magnesium minerals have shown wide application potential in many fields due to their unique chemical and physical properties. With the advancement of technology and the growth of market demand, the development, processing technology and application research of these resources are also deepening.
