Product Description

High Purity Limestone

The raw material for all lime-based products is a natural stone. limestone, which is composed almost exclusively of calcium carbonate (CaCO3). 

It is widely geographically available all over the world, (the Earth's crust contains more than 4% calcium carbonate,) and it is used for many different purposes.

In the lime production process, the blocks of limestone or dolomite from the quarry are blasted, crushed and sorted by size in screening plants. At this stage, a part is used directly as aggregates for road construction, for concrete or other applications.

Another part is ground to lime fertilizer or pulverized into limestone powder, used in applications such as for cleaning flue gases, for animal feed or for fillers in many products (concrete, asphalt, etc.).

The rest of the high-quality limestone, with defined particle size, is calcined in a lime burning plant at a temperature of 900-1200°C, at which temperature it is decarbonized in either vertical shaft or horizontal rotary kilns fired by gas, oil, coal, coke or other fuels. During that process, carbonate is converted into oxide (CaO) and CO2 is released.
