· Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
Rocks. Rock Products and Uses Limestone.. The Manufacture and Uses of Lime.. What is Lime?. The name "lime" is used for both calcium oxide (quicklime),and calcium hydroxide (slaked lime).. How is Quicklime (Calcium Oxide) Made?. When limestone (calcium carbonate) is heated, at about 1000 °C it undergoes thermal decomposition. It loses carbon dioxide and turns into quicklime (calcium oxide).
Surface limestone mining. All over the world, the limestones are generally mined from a quarry or the open pit mining. It is the easiest way to remove the limestone without causing much destruction. In surface mining or open pit mining, the top soil and the overburden covering the mineral is removed. Then by the process of drilling the rocks or ...

· Haematite, coke and limestone are fed into the furnace through the top. The following process takes place inside the blast furnace: Coke is added to haematite as it acts as a reducing agent for iron(III) oxide. Carbon, which comes into contact with haematite, reduces some of the iron(III) oxide. Reduction of iron(III) oxide:

When limestone is subjected to heat, pressure, and chemical activity, the calcite in the rock begins to transform. This is the beginning of the process known as metamorphism. Starting at a microscopic scale, the calcium carbonate in the rock begins to crystallize or recrystallize into finegrained calcite crystals.
The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.
