Natural Brucite Ore Mg(OH)2 

Composition of Brucite Brucite is natural magnesium hydroxide, also known as hydrated magnesia. Melting point (dehydration) 340 ° C, relative density: 2.39, hardness: 2.5, crystal structure: six crystal systems, relative molecular mass: 58.32, solubility: 0.009 g / L. Brucite has a simple chemical composition and its molecular formula is Mg(OH)2. Brucite is a rare high-magnesium mineral in nature. Its theoretical chemical composition is MgO 69.12% and H2O 30.55%. It is often found in brucites produced in nature. Impurities such as Fe, Mn, Zn, Ni, etc., these impurities exist as a homogeneous image, forming a series of continuous or discontinuous solid solution, constituent endmembers: iron brucite (including FeO 10%), manganese brucite (containing MnO 18%), zinc brucite (including ZnO 4%), nickel brucite (including NiO 2.5%). The associated minerals of brucite are serpentine, calcite, dolomite, magnesite, magnesium silicate mineral, periclase, diopside and ta…
