About 98% of world iron ore production is used to make iron in the form of steel. Iron in cast form has many specific uses (e.g. pipes, fittings, engine blocks) but pure iron is quite soft. Adding a small amount of carbon (usually less than 1%) makes iron into steel which is significantly harder and extremely versatile.

Magnetic separation is typically used in the beneficiation of high grade iron ores where the dominant iron minerals are ferro and paramagnetic [1,5]. Wet and dry low-intensity magnetic separation (LIMS) techniques are us ed to process ores with strong magnetic properties such as magnetite while wet high-intensity

Oct 04, 2018· Magnetic separation methods are used to take the advantage of the difference in the magnetic properties for separating iron ore from the non-magnetic associated gangue materials. Magnetic separation can be conducted either in a dry or in a wet environment, although wet systems are more in use.

Dec 17, 2020· First,Strong magnetic iron ore . 1.Single magnetite . The composition of iron ore of a single magnetite type is simple, and the proportion of iron minerals is very large. Gangue minerals are mostly quartz and silicate minerals. According to production practice research, weak magnetic separation methods are often used to separate them.

This is similar to the porosity values of the commercial lump iron ores used in the blast furnace (5.9% for MBR Brazil iron ore) and the direct reduction processes (1.2–5.2% for Orissa India iron ores) . Furthermore, sample Ug5, whose chemical composition is similar to that of samples Ug1-4 had a higher porosity value of 14.3%.
