The process flow diagram shows precipitated calcium carbonate (PCC) production from limestone[/caption] Calcination. Initially, the limestone from a quarry is stored in bins. Typical extracted limestone contains about 75 wt.% of CaCO3. Mined limestone is crushed in a jaw crusher and calcined (burned) in a vertical-shaft lime kiln at about 1,000°C.
Limestone and dolomite are mined by opencast methods and sold either in bulk, powder or slurry form. Several companies reclaim residual limestone 'fines' from slime dams. Quicklime Limestone is converted to quicklime through calcining in rotary or vertical kilns. In the lime process, for
