    WHERE IS IRON ORE MINED? - Technology Student
    Iron ore can be found all over the world, in the form of rocks and other minerals. To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is

    Chromite mining - The Oregon Encyclopedia
    Most operations were small, and many investments found little return. When the grade of the chromite was low, mills were needed to concentrate the ore; miners often converted mills used for gold. During World War I and World War II, Oregon''s contribution to the domestic production of chromite varied from one-fifth to one-quarter.

    Chromium - Wikipedia
    Chromium compounds are found in the environment from the erosion of chromium-containing rocks, and can be redistributed by volcanic eruptions. The two main products of chromium ore refining are ferrochromium and metallic chromium. For those products the ore smelter process differs considerably.

    Chromium - Periodic Table of Elements and Chemistry
    Source: Chromium is not found as a free element in nature but is found in the form of ores. The main ore of chromium is chromite FeCr 2 O 4. To isolate the metal commercially, chromite ore is oxidized to chromium(III) oxide (Cr 2 O 3). The metal is then obtained by heating the oxide in the presence of aluminum or silicon.
