Magnetite Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces

Vibrating screens with apertures of about 150 μm are also used in the flow sheet to take out unliberated coarse quartz particles that contain mainly quartz and a small portion of magnetite, which are returned to the ball mill for regrinding. Magnetic thickeners are used for slurry dewatering and rejecting some of the light and fine gangue

Eco-efficient and cost-effective process design Metso

Feb 24, 2015A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates eco-efficient alternatives for the process design for magnetite iron ore.

Conversion of Mill Scale Waste into Valuable Products via

Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a

Elimination of ImpuritiesMagnetic SandsBriquettingSeparation of Magnetite as An ImpurityThe objectionable elements occurring with magnetite which are wholely or partially eliminated by magnetic concentration, are, in the order of their importance, phosphorus as apatite, sulphur as pyrite, etc., and titanium as menaccanite or ilmenite.Apatite (calcium phosphate, sp. gr. 3.18 to 3.25) is usuallyfeebly magnetic, though not sufficiently so to be picked up by magnetic fields of low intensity; a red variety, found at Mineville, N.

At Bagga, Sweden, a Grondal Type I separator is working on an ore carrying magnetite, hematite, amphibole and quartz. It averages from 30 to 40 per cent. iron. The finished product amounts to 63.7 per cent. of the raw ore and carries from 60 to 62 per cent. iron. Ball mills are used for fine grinding.

Mill scale Wikipedia

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
