Why Is Open-Pit Mining So Devastating to The
2022-3-30 Open-pit mining is a process of digging the earth’s surface to extract ores or minerals present in a shallow layer. In case of mineral ores present deep down, we require an underground tunnel to remove them. That’s not under an open atmosphere like open-pit mining. The shape is already determined and optimized for maximum profit in surface mining.
