different types of iron ore and its mineral formula

  • Ruby and Sapphire Gems of the Mineral Corundum Geology

    Ruby, Sapphire, and Fancy Sapphire. Most people don't realize that ruby and sapphire are both gems of the mineral corundum.Both of these gemstones have the same chemical composition and the same mineral structure. Trace amounts of impurities determine if a gem corundum will be a brilliant red ruby or a beautiful blue sapphire.

  • Pyrite The mineral pyrite information and pictures

    Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.

  • Hornblende The amphibole mineral hornblende information

    Hornblende is usually an uninteresting gangue material, especially when it is confused with ore minerals due to its shiny luster. Good crystals are infrequent and are used as collector's material when found. Hornblende is a constituent of granite, and is responsible for the black streaks in the granite that provide a desirable color variety and contrast.

  • Pegmatites and aplites Their genetic and applied ore geology

    Definition The term ore is defined in the current study to describe a concentration of non metallic, e.g., feldspar, or metallic minerals, e.g. spodumene, in pegmatitic rocks irrespective of its structure and position in the deposit which was or is currently mined for a profit.
