Environmental Issues in Gemstone Mining Gemstones

Environmental Issues In Gemstone Mining Gemstones

Environmental impacts of mining largely depend on the methods used and the geological context that governs how easily the minerals can be separated from the ore material. Unlike gold mining, which often uses potentially toxic chemicals such as mercury and cyanide, gemstone mining does not depend on chemicals for extraction of the rough material.

Open Pit Mining Techniques Surface Mines Rock Or Mineral

Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.
