Extraction, crushing, washing, screening, grinding stones

 

Calcium carbonate is a natural product that can be found as marl, chalk, limestone or marble.
The very pure limestone that Carmeuse extracts to make lime is light to dark grey in colour with a CaCO3 content of about 98% to produce calcium or dolomitic quicklime (CaO or CaO.MgO respectively).

The pebbel-lime thus produced is screened, crushed or ground and finally stored, all of this according to customer specifications.

Limestone either in the form of calcium carbonate (CaCO3) or dolomite (CaCO3.MgCO3), is extracted (sorted by mass) selectively, according to its physical and chemical characteristics.   Gathered by mechanical loaders or buckets, the rocks are then transported and unloaded in crushers where they are washed, screened, crushed, ground and stored according to their use.
