  • Magnetite: The mineral Magnetite information and pictures

    Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.

  • What Are the Uses of Magnetite? Reference

    The magnetite can be reused in this process 90 percent of the time. Magnetite is also used as a source of iron to manufacture ironbased chemicals and fertilizers. Ferric chloride and ferric sulphate are manufactured with magnetite as one of the starting materials. These chemicals are effective in clarifying raw water in water purifiion plants.

    Magnetite crystallizes in the cubic system, usually in octahedra, less commonly in rhombic dodecahedra, and not infrequently in twins of the " spinel type " (fig. I). The rhombic faces of the dodecahedron are often striated parallel to the longer diagonal. There is no distinct cleavage, but imperfect parting may be obtained along octahedral planes.

    Magnetite rarely occurs in the form of colloform aggregates. Synthesized magnetite is widely used in industry. It is usually obtained by synthesis in the solid phase following the combined roasting of pressed FeO and Fe 2 O 3 powders at temperatures of 10001400°C. Magnetite is brittle with an uneven fracture it exhibits no cleavage.
