Nov 01, 2018· Open pit mining (also known as strip mining) is the process of extracting ore, minerals and/or fossil fuels that occurs on the surface of a particular mining site. When considering all the mining operations in the world, at least 40 percent of mining takes …
Jul 31, 2017· 2. 2 Introduction Open pit mining is the process of mining a near surface deposit by means of a surface pit excavated using one or more horizontal benches. The term open pit mining is usually used for metallic or non-metallic deposits and sparingly used for bedded deposits like coal. A quarry is a type of open pit mine used to mine building ...
The open pit or open cast mining method is the obvious choice for a property with a wide area of mineralization exposed or existing close to the surface and continuing to greater depths. The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks.

Open-pit Mining. Open-pit mining is a method in which an ore is removed by digging a pit in the ground, and is used to remove copper, gold, iron, as well as non-metallic minerals. It is normally used when the rock layer above the ore is too weak to allow underground tunnels. In this technique, circular steps, or 'benches', are dug around ...
Oct 08, 2019· The two foremost kinds of surface mining are open-pit mining and strip mining. Open pit mining involves digging out rocks to form an open pit or borrow pit, from which resources are then extracted. An open pit mine generally has stepped sides to minimize the risks associated with collapse and a large ramp for mining equipment.
Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is employed when the orebodies are extensive, low in grade, and relatively near the surface, …
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Open Cast Mining/Strip Mining Introduction As the name speaks, it is a surface mining system in which deposit is opened to the atmosphere and after removing the orebody, the over burden which was blanketing it, is cast back in the worked out area. This is also known as Strip Mining.
