How Are Emeralds Mined? | LEAFtv

Open-Pit Mining. One way to mine emeralds is through the open-pit method. Workers dig a large pit about 12 meters deep and then blast the surface with water to reveal mineral-bearing rocks. In the open-pit mining method, a lot of waste rock must be hauled away. The mining area is literally shaped like a pit that can hold equipment and workers.
