Magnetite

Description:
The chemical composition of magnetite is Fe3O4, the crystal is an oxide mineral of the equiaxed crystal system, and the crystal is often octahedral and rhombic dodecahedron, and the aggregate is granular or massive. A perfect single crystal is an octahedron or a rhombic dodecahedron. When it is a rhombic dodecahedron, there are often stripes on the rhombic surface parallel to the long diagonal direction of the crystal plane. The aggregate is dense block or granular. The color is iron black, with black streaks, metallic or semi-metallic luster, opaque, no cleavage, Mohs hardness 7-8, ;Surface-dried specified gravity:4.5-5.0g/cm3
 
Application:
AS to its high specific gravity, it is an important material for counterweight materials.
1. Bridge counterweight, elevator counterweight, mechanical counterweight.
2. Concrete counterweight; can also be used in radiation-proof concrete (weakening the penetration strength of neutron flow) 3. Sporting goods and fitness equipment counterweight
4. Electric counterweight
5. Hull large-scale mechanical engineering machinery weight, wear-resistant engineering, such as airport runways, bridge pavement, docks, bridges, steel plants, etc.
