The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron (III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced

The basic processes in the production of limestone are (i) quarrying of raw limestone, (ii) preparing mined limestone for its use by crushing and sizing, (iii) calcining of raw limestone, (iv) processing the calcined limestone further by hydrating to produce hydrated lime if required for use, and (v) miscellaneous transfer, storage, and handling operations.

This process does not melt the rock but changes the rock by growing new crystals from the original composition of the rock. Often the crystals lie in a particular direction due to the pressure. This change is known as metamorphism and the rock becomes a metamorphic rock. e.g. limestone becomes marble with an increase in temperature and pressure (pictured right).

In fact, extracting pure calcium via electrolysis, the developed process is clean and reduces unwanted wastage. However, in terms of mining its ore, there are a few issues, environmentally in particular. In terms of quarrying limestone (an ore of a calcium), the waste product and results of pollution need to be taken into account.

The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9. The sinter process is widely used to process the poor-grade diasporic bauxite ores with A/S below 7, in China and Russia, by sintering the bauxite ore with sodium carbonate and limestone to form sodium aluminate and calcium silicate.

Karstification of many glacially scoured limestone pavements would have begun under acidic soil cover, with biological soil processes contributing to smooth, rounded cryptokarstic surface forms. Holocene soil erosion is attributed to anthropogenic activity, climatic fluctuations and the evolution of the karstic groundwater system leading to vertical soil loss through widening grikes.

Rocks containing groundwater that can be extracted are called aquifers. Some rock types, such as sandstone, limestone and chalk, make good aquifers because they have lots of cracks and for water to pass through. Other rock types, like granite, have less gaps so water can’t pass through. These rocks make poor aquifers.
