Iron Ore Statistics and Information - USGS

Iron Ore Statistics and Information. Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel ...


The Iron making is necessarily a reduction process, as far as the chemical theory is concerned, where reduction of the iron ores takes place to produce metallic iron. • Iron ores: Generally in Oxides: Hematite (Fe 2 O 3), Magnetite (Fe 3 O 4) Mass number (55.85) Density=7.874g/cc Atomic number (26) m.p= 1538° C b.p= 2861° C Fe Iron (Latin ...

COPPER Copper production

Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation.


Iron ore crushing is not required since sized material has to be purchased. Iron ore of size 5 mm to 20 mm is being used for the production of Sponge iron. Iron ore is being fed to the Ground hopper, from where it conveyed to the Screen with the help of Vibro Feeder, where Oversize i.e. + 20 mm and Undersize i.e. – 5
