The extraction of granite involves the following steps:

1. Quarrying: This involves removing blocks or slabs of the granite from the surface or subterranean deposit. This may be done using drilling and blasting techniques, wire saws, or chain saws.

2. Cutting: The blocks or slabs are then cut to the desired size using saws or other cutting equipment.

3. Polishing: After cutting, the granite pieces are polished to give them a smooth, polished surface.

4. Finishing: Finally, the granite pieces are finished to prepare them for installation. This may involve adding edge profiles, cutouts, or other customizations.

Overall, the extraction of granite is a complex and labor-intensive process that requires sophisticated equipment and skilled workers.
