Iron ore - Wikipedia

Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth-most abundant element i…Study on Pulp Grade of Iron Ore Concentrate by Monte Carlo,When energy distribution X-ray fluorescence analysis method (EDXRF) is used to measure the pulp grade of iron concentrate, the parameters such as the location of radioactive source, detector, the particle size of the iron concentrate, and the concentration of the iron concentrate slurry, etc. have a greater influence on the measurement results.The ProducTion of high grade iron ore concenTraTes using,,recleaner column feed grade ranges between 1% and 6% silica, therefore, one column stage is sufficient to produce either blast-furnace or direct-reduction concentrate. a scavenger column has been added to the flowsheet to maximize fine iron recovery particularly during the periods where direct reducing grade is being produced.

Mechanical CircuitIron Ore - Department for Energy and Mining,Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World's early history of production of iron. Since the 1950s North America's main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite.Global Drivers for High Grade Concentrate | Magnetite Mines,/ global drivers for high grade iron ore concentrate Over the last decade, there has been structural shift in the global iron ore markets favouring higher-grade, lower-impurity iron ore products. Generally, the lower the Fe grade of the iron-based feedstock, the higher the level of impurities such as phosphorus, silica, sulphur and alumina.
