Open pit is the type of mining used to mine minerals near the surface. It is also known as open-cut mining, opencast mining and strip mining. It is different from any other kinds of mining, because open pit mining no longer needs to use extensive extracting methods which use tunnels into the Earth. If minerals are found near or close to the Earth’s surface, then open pit mines will be used. Some of the minerals which are typically extracted from open pit mines are as follows: clay, coal, copper, diamonds, gravel, granite, gypsum, limestone, marble, uranium and phosphate. Here are some examples of open-pit mines in the world:
The Escondida Copper Mine found in Atacama Desert in Chile, the Udachny Diamond Mine found in Eastern-Siberian region of Russia, the Grasberg Mine located in the Papua province of Indonesia and the Kimberly Diamond Mine located in South Africa.
