How is iron usually separated from its ores

Jan 27, 2009 Most iron ores are iron oxides or iron sulfides. Iron ores are also usually hydrated (i.e. includes water of crystallization). A variety of other metal ores (e.g. copper, zinc, lead) are sometimes

    Meteorites that have fallen from space are the only iron found in nature in its pure form. Iron is found naturally in the form of ores that are oxides of the pure metal, such as hematite and magnetite. The most common of the modern methods used to extract iron from its ores is coke smelting in a blast furnace

    Smelting usually requires a reduction agent, or another chemical, to separate metal from its ore. In the earliest smelters, the reduction agent was carbon in the form of charcoal. Charcoal burned with hematite ore, for instance, smelts iron. Electrolysis separates metal from ore by using acid and electricity. Aluminum, which burns at a very

    iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is

    Jun 21, 2018 Ore processing (or ore dressing) is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process
