  • Blast Furnace: Definition, Construction or Parts, Working .

    Iron ore is added with a mixture of coke (around 5% of the mixture) and lime (around 20% of the mixture). Coke is the main source of carbon (reducing agent) for producing carbon monoxide and also acts as a fuel. On the other hand, lime acts as flux ( a compound which mixes with the impurities to form slag).

  • Basic impurities are removed as slag in the production of iron.

    Iron is extracted from its oxide. Extraction of iron is based on the reduction of Haematite(Fe2 O3 ) with carbon. Slag formation: Lime stone on heating decomposes to CaOand CO CaCO3 →CaO+CO2 CaO now reacts the impurities of ore called Gangue to form slag. Slag is the mixture of CaSiO3 and Ca(AlO2 )2 . The slag floats over the top of molten iron.

    There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.
