The stages of mining: 5 lifecycle processes explained
Soil, rock, and vegetation over the mineral seam is removed with huge machines, including bucket-wheel excavators. Open-Pit Mining is a technique of extracting rock or minerals from the earth by their removal from an open-air pit. Open-pits are sometimes called 'quarries' when they produce building materials and dimension stone.
