Green minerals empower industrial upgrading. High-purity mineral-based magnesium hydroxide leads the new trend in environmentally friendly materials.

Based on the abundant brucite mineral resources in China, the high-purity mineral-based magnesium hydroxide of magnesium hydroxide has achieved process upgrading and large-scale promotion. This product is made from natural brucite as the raw material, through processes such as selection, ultra-fine grinding, purification, and modification. With advantages such as controllable cost, environmental friendliness, and flame retardancy and smoke suppression, it has become the preferred material in fields such as engineering plastics, wires and cables, and environmental governance, promoting the development of magnesium-based functional materials towards a low-carbon and efficient direction.

Natural endowment: Green raw materials sourced from mineral deposits
The core raw material of the mineral-based magnesium hydroxide of magnesium hydroxide is brucite (natural magnesium hydroxide), with the original ore containing Mg(OH)₂ content ranging from 90% to 98%, having few impurities and high whiteness, making it an ideal natural magnesium source. The brucite reserves in Liaoning and Shandong provinces of China are abundant, providing stable and low-cost raw material guarantees for the mineral-based magnesium hydroxide process, and compared with chemical synthesis methods, significantly reducing raw material and energy costs.

Process innovation: From rough processing to refined
The traditional mineral-based magnesium hydroxide process can only produce coarse powder with a particle size of 10–50 μm, with a purity of ≤ 94%, and its application is limited. Through technological upgrades, the modern mineral-based magnesium hydroxide adopts four core processes: low-temperature activation, ultra-fine air jet grinding, multi-stage purification, and surface modification.

Selection and separation: High-grade brucite is crushed and then processed by manual and mechanical beneficiation to remove silicon, calcium, iron, etc. as impurities;
Ultra-fine grinding: Using equipment such as air jet mills and vertical mills, the particle size can be controlled to 1–5 μm, and some high-end products can reach 0.8–1.5 μm;
Purification and refinement: Wet classification + ultra-pure water washing, the purity is increased to 96%–98.5%, and the whiteness is ≥ 95%;
Surface modification: Silane, stearic acid coating, to improve compatibility with polymeric materials. 

Core advantages: High cost-effectiveness and environmental friendliness are combined
Green and low-carbon: No chemical reactions throughout the process, no wastewater or exhaust gas emissions. The energy consumption is approximately 30% lower than that of chemical methods, in line with EU REACH and RoHS environmental standards.

Flame retardant and smoke suppressant: The decomposition temperature is about 330℃. When heated, it decomposes, absorbs heat, and releases water vapor, resulting in a significant smoke suppression effect. There are no toxic halogen gases during combustion, and it is in line with the trend of halogen-free flame retardancy.

Stable performance: Uniform particle size distribution, good thermal stability, low hardness, little wear on equipment, and excellent processing fluidity.

Cost advantage: The cost of raw materials and processes is lower than that of chemical methods, making it suitable for large-scale industrial applications.
