Mining vs. Quarrying — What's the Difference?

Key Differences. Mining is the process of extracting ores, coal, precious stones, and metals from beneath the earth's surface. It often involves digging underground tunnels and shafts to reach these materials. On the other hand, quarrying is specifically the extraction of stone and other construction materials from open pits or quarries.
