What raw materials are used in a blast furnace?
Iron ore or Haematite (Fe3O2), Carbon in the form of 'Coke', and Limestone (Calcium Carbonate 'CaCO3') are all used in the blast furnace. Iron Ore is melted down with coke, the coke burns heat into the furnace. Oxygen gas is blasted in from the sides. The carbon (C) and oxygen (O2) react to form carbon dioxide gas (CO2). At higher temperatures more carbon (C) is reacted with the carbon dioxide(CO2) to create carbon monoxide (2CO). The carbon monoxide 'steals' the oxygen from the iron oxide (Fe3O2), reducing the iron oxide to iron. Due to the impurities in the iron, it is called 'pig iron'. Limestone (CaCO3) is added to remove the impurities from the iron. The limestone (CaCO3) reacts with mainly silicate in the iron, and becomes calcium silicate (CaSiO3) and carbon dioxide (CO2). Calcium silicate is known as 'slag' and is used for construction.
Why is carbon used to extract iron from it's ore?
The carbon combines with the oxygen in the ore, separating it from the iron.Excess carbon alloys with the extracted iron, hardening it.
Is iron a metal used to make steel?
Steel is made of iron to which is added between 0,02 % and 1.67 % of carbon.If you go over 2% of carbon, you'll get cast iron instead of steel.
What is the use of carbon dioxide?
used by plants and trees to be turned into oxygen.
Steel is formed when a little bit of carbon is added to this element.?
Iron (Fe) is the main component of steel. Steel is formed when iron is mixed with carbon or other elements.
What is the chemical reaction that is used to separate iron from its ore?
Heat-reduction with Carbon (coale)
Which metal CAN BE USED in an attempt to tie up carbon?
Iron is one of the metals of which can be saturated with carbon. It is commonly used to make Iron harder. Unfortunately it will also make the Iron brittle. Iron with a lot of carbon in it can break and shatter if hit hard. Iron without carbon is "soft" and will most likely only bend.

Carbon
What is the difference between cast iron wok and carbon steel wok?
The difference between cast iron and carbon is steel is the percentage of carbon which is present in the alloy. For cast iron this is between 2.5%-6.67% and for steel this is generally lower than 1.9%. Due to these properties the cast iron wok generally spreads the heat more equally and maintains this temperature much easier than the carbon steel wok. Because of this, it takes a bit longer to heat up. The carbon steel wok heats up very fast and is preferably used when a dish does not need to cook very long.

Name an element that could be used to remove oxygen from iron oxide?
Carbon iron oxide - oxygen = carbon dioxide
What liquid can be used to separate mixture of iron filings and sulfur?
Carbon disulfide can be used to separate a mixture of iron filings and sulfur. This is because carbon disulfide can be used to dissolve sulfur, thus leaving you with the iron filings.
What metal is used with carbon to make steel?
Iron
What metal is used to make an alloy with carbon?
Iron is mixed with Carbon to make Steel.
What is carbon monxide used for?
Carbon monoxide can be used as a fuel for inndustrial operations, its used in Fischer-Tropsch process, and as a reducing agent (For example, when it passes over hot iron oxides, the oxides are reduced to metallic iron, and the carbon monoxide is oxidized to carbon dioxide.)
What are uses for iron?
Iron is used for making steel, together with carbon. If you mix iron and carbon together at a ratio of 99% steel and 1% carbon, you get an alloy called hard steel. Which, as its name suggests, is very strong.
