It is carbon (in the form of coke) that is added to blast furnaces to reduce iron oxide and recover the iron This is the usual explanation, though most believe that it is the action of carbon .
Occurring in the earth in the form of several ores, iron is the cheapest, second most abundant, and most widely used metal An impure form of iron (pig iron) is produced from a mixture of ore, coke, and limestone in a blast furnace Pig iron is usually refined either by the basic oxygen process or by the electric arc process
However, cast iron is naturally prone to rusting because of its high iron composition When iron comes into contact with oxygen and water vapor, a chemical reaction occurs, and rust is the visible result Keeping cast iron in an environment with a humidity lower than 30 percent reduces corrosion

An innovative approach involves the replacement of iron salts, which are commonly used for phosphorus removal, with ferrous ions produced by iron‐reducing bacteria from iron ore The aim of the research was to examine the feasibility of phosphorus removal from return liquor using bioreduction of iron ore
How do we extract iron from its mineral ores? How do we convert it into steel? The raw materials needed ie limestone, coke, air and iron ore and the chemistry of the blast furnace are fully described Why convert iron into steel? How do you make steel? The manufacture of steel alloys is further described Scroll down for revision notes on extraction procedures and theory which should prove .
A Brief Review of Iron Ore Beneficiation & Trace Elements Beneficiation is a variety of processes whereby extracted ore from mining is reduced to particles that can be separated into mineral and waste, the former suitable for further processing or direct use
In chemistry rusting is called as oxidation Oxidation is a chemical process where metal gains oxygen and become oxide In rusting the Iron ore make a chemical reaction with the oxygen in the presence of water and environmental or atmospheric moisture to produce an Iron oxide Iron ,
