In simplest terms: grind the ore rock to powder, keep the powder that sticks to a magnet. Somewhat more detail: the large iron mining companies here use the open pit method. Move the soil off the top until they reach the ore vein, blast the rock with explosives into quarter ton or smaller pieces, use heavy moving equipment to bring the ore to the crushing and processing plant (usually less than two miles away). The next several steps are crushing and grinding the ore to a powder. Then the ore powder is usually mixed with water to form a "slurry" to make it slightly easier to handle. Then it is magnetically separated, and the magnetic stuff is filtered and dried, then baked into small round balls called "pellets" that have specific chemical and physical characteristics. These pellets are sent directly to iron refineries (somewhere else like Pittsburg or Detroit) to be melted and formed into iron and steel parts. Incidentally, each of the above steps and several others support many good size businesses in the area around the mines, each of which support other businesses.

What is an example of an abstraction?
Abstraction is a process of obtaining or removing something from a source. The process of evaporation is an example of extraction. In evaporation, the process of changing a liquid into a gas, removes some or all of the liquid which is given off in the form of vapor.An example is the extraction (abstraction) of salt from sea water using evaporation ponds.
What is an example of a ferromagnetic material?
Iron
Is The magnetization of an iron rod an example of a chemical change?
No. Iron is naturally magnetic.
What type of mixture is iron?
Steel Iron carbide or just plain carbide.
What is the biggest impurity in the extraction of iron?
The problems that iron impurities can cause in a blast furnace can include the iron not melting down correctly, obnoxious fumes being created, and the impurities could ruin an entire batch of melted iron.
What is the word equation for the extraction of iron from the ore iron oxide?
Iron oxide + carbon monoxide -> iron + carbon dioxide
Why aluminum is not used as the reducing agent in iron extraction?
Aluminum is not used as the reducing agent in iron extraction because it has a higher reduction potential than iron, meaning it is not able to reduce iron oxide to elemental iron. Carbon, on the other hand, has a lower reduction potential than iron and is commonly used as the reducing agent in the extraction of iron.
What raw materials in the extraction of iron?
The raw materials used in the extraction of iron are iron ore, coke (made from coal), and limestone. Iron ore is the primary source of iron, while coke is used as a reducing agent and fuel, and limestone helps to remove impurities from the iron ore during the smelting process.
What is the large vessel in which the extraction of iron by carbon reduction is carried out?
Blast Furnace
What is the balance equation for extraction of iron from its ore?
The balanced equation for the extraction of iron from its ore involves the reaction of iron oxide (Fe2O3) with carbon monoxide (CO) to produce iron (Fe) and carbon dioxide (CO2). The balanced chemical equation is: Fe2O3(s) + 3CO(g) → 2Fe(l) + 3CO2(g).
Why is limestone added to the blast furnace during the extraction of iron?
Limestone is added to the blast furnace during the extraction of iron to act as a flux. It helps to remove impurities, such as silica, from the iron ore by combining with them to form slag. The slag can then be easily separated from the molten iron.
What the main ore of iron?
Hematite and Magnetite are the main ores of Iron.
How is iron found in nature and what are the processes involved in its extraction?
Iron is commonly found in nature in the form of iron ores, such as hematite and magnetite. The extraction of iron involves several processes, including mining, crushing, and smelting. First, the iron ore is mined from the ground and then crushed into small pieces. The crushed ore is then heated in a blast furnace with coke (a form of carbon) and limestone. This process, known as smelting, separates the iron from the other elements in the ore, producing molten iron that can be further processed into various forms.
What is the function iron ore in a blast furnace?
Iron ore is used in a blast furnace as a raw material for producing iron. It is the primary source of iron, which is essential for the production of steel. The iron ore undergoes a series of chemical reactions in the blast furnace, resulting in the extraction of molten iron.
What has the author Niels Nielsen written?
Niels Nielsen has written: 'Evidence of iron extraction at Sandnes, in Greenland's west settlement' -- subject(s): Northmen, Iron, History
When is electrolysis used for extraction?
Electrolysis is used for extraction in processes where a metal is extracted from its ore using electricity. It is commonly used for the extraction of reactive metals like aluminum and sodium from their ores. The process involves passing an electric current through a molten or dissolved salt of the metal to break it down into its individual elements.
What is the method of iron extraction?
they heat in to hot temparatures and then it melts and they celebrate with lots of wine and children throwing contests :)
