The incredible marble extraction process – Stone and Style

The incredible marble extraction process. Extracting giant marble blocks from a quarry is amazing and beautiful. Check the article complete here. Marble deposits can be exploited in open pits, it can be 95% on outdoor quarries and 5% in caves or mines. Marble is located at ground level or at great depths which make the cost too high for removal.
