Raw materials for Glass Manufacturing:
Limestone which is present in the earthen crust across the globe is primarily formed when the remains of coal animals and plants are compacted on the ocean bottom. There are mainly two types of Limestone. The classification is based on the composition. One type is the mineral calcite which contains the calcium carbonate and the mineral type is dolomite which contains the carbonates of both calcium and magnesium. Both the above said types also contain small amounts of other minerals.
There are three distinct types of limestone which are defined by their magnesium carbonate (MgCO3) concentrations:
Dolomite limestone: This type contains about 35 to 46% of magnesium carbonate in it.
Magnesian limestone: This type contains about 5 to 35% of magnesium carbonate in it.
High Calcium limestone: This contains about less than 5% of magnesium carbonate in it.
