    2017-10-10  Roasting or calcination of the ore oxidizes some of the sulfur, phosphorus and arsenic impurities. Sulfur oxide is volatile and evaporates off or is washed out. Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace.

    2017-7-1  Pyrite, iron sulfide (FeS 2), is a common mineral in many rocks. Geochemically speaking, pyrite is the most important sulfur-containing mineral. (more below) Pyrite occurs in this specimen in relatively large grains associated with quartz and milky-blue feldspar. Pyrite has a Mohs hardness of 6, a brass-yellow color and a greenish black streak.

    The ratio between ore and vein minerals varies greatly, depending on the metal and the given deposit. For example, in veins of gold-bearing quartz the amount of gold relative to the mass of the quartz is thousandths of 1 percent. On the other hand, some types of iron ore consist entirely of ore mineral (magnetite, hematite).

  • Metal Profile: Iron Properties and Characteristics

    2020-1-12  History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
