Extraction of metals The process of extracting metal ores buried deep underground is called Mining The metal ores are found in the earth’s crust in varying abundance The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridg
Dec 04, 2006· Best Answer: In order to obtain elemental iron, the impurities must be removed by chemical reduction Industrially, iron is extracted from its ores, principally hematite (nominally Fe2O3) and magnetite (Fe3O4) by a carbothermic reaction (reduction with carbon) in a blast furnace at temperatures of about 2000Â°C
Extracting iron from iron ore using a Blast Furnace , This section deals with the types of iron and steel which are produced as a result of the steel-making process Wrought iron: If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron Wrought iron is quite soft and easily worked and has little .
The process of extracting iron from ore produces great quantities of poisonous and corrosive gas In practice, these gases are scrubbed and recycled Inevitably, however, some small amounts of toxic gases escape to the atmosphere A byproduct of iron purification is slag, which is produced in huge amounts .
Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore Open pit: 90% of ore is mined by this method Ores near the surface can be quarried after removal of the surface layers The ore is treated with dilute sulfuric ac
The basic process to extract iron from ores is to oxidize the ore into iron oxides (such as FeO, Fe2O3, etc) The iron oxides are melted and mixed with charcoal or coke (carbon from purified coal)
The process of separating a metal from its ore is known as smelting Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique Smelting methods range from the basic to the high-tech, and are applied to a variety of materials, including aluminum, iron and copper
Mar 07, 2010· What is the chemical equation for making iron from its ore?
