Magnetite

Magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral (FeFe 2 O 4, or Fe 3 O 4) that is the chief member of one of the series of the spinel (q.v.) group.Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites, and high-temperature sulfide veins.

Iron ore raw materials

Sinter ore (iron-ore fines) is produced by crushing, screening and deslurrying high-grade ore rich in iron, fineness being less than 10 mm. Direct-shipping ore (lumpy ore) is also produced from high-grade ore, fineness being minus 70 and plus 10 mm. Iron-ore raw materials for a blast-furnace process are usually sintered or pelletized.

iron ores and impurities

US4405588A. A process of removing iron impurities from ores, particularly useful for removing stains of iron impurities adhered to silica sand particles, comprises grinding the ore, washing and desliming the ground ore to remove the major part of the clay-type binder, attrition-scrubbing the deslimed particles to release further amounts of binder therefrom, washing and desliming to remove said Get price

Iron ore

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and Get price

magnetite ore grade

May 03, 2017 Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but the presence of impurities usually results in magnetite ores having lower ore grade (generally 20-30% Fe) than hematite ores, making it more costly to produce concentrate for steel smelters. Get price

5 Ways To Trade Iron Ore In 2020

Examples of these iron ores include magnetite, hematite and limonite, although other ores also may contain iron. Iron Ore in the Mountains of Peru – Image via Pixabay. Pit-crushing machines pulverize the ore and separate the iron from impurities such as sand and clay. The best grades of ore contain close to 70% iron and usually require Get price

Magnetite Concentration Methods

Table of ContentsElimination of Impurities Magnetic Sands Briquetting Separation of Magnetite as an Impurity Magnetite is the most strongly magnetic of all minerals, and it is therefore natural that the earliest application of magnetism to ore dressing was for its concentration from gangue. Magnetite ores occur in large bodies in almost all countries, and on account of the high iron tenor of Get price

Iron Ore

It is generally black and highly magnetic, the latter property aiding in the beneficiation of magnetite ores. Mineral magnetite contains 72.4% iron, which is higher than hematite but the presence of impurities results in lower ore grade, making it more costly to produce the concentrates used in steel smelters.
