Process of making iron to iron ore

Oct 10, 2017 Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore

    Iron ore can be bought or gathered, but for the sake of demonstration, we gathered the ore ourselves. The best time to collect iron ore is in the winter because the ocean is more active. Active waves separate the black, magnetic sand from lighter silica sand. This magnetic sand is an iron ore called magnetite, which when combined with carbon

    During this process the water content of the iron ore is released, and its structure becomes looser, which makes it easier to smelt. Finally, we break up the burnt iron ore into 2-3 cm pieces to make it easier to load the iron ore into the furnace during the smelting process (See Figure 3)

    Instead, the iron heats up into a spongy mass containing iron and silicates from the ore. Heating and hammering this mass (called the bloom) forces impurities out and mixes the glassy silicates into the iron metal to create wrought iron. Wrought iron is hardy and easy to work, making

    How is Iron Refined from Ore? (with pictures)

    Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires
