open pit mining method

Opencast Mining

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...

Uranium: How is it Mined?

Open Pit Mining Open pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below Ore grades are normally less than 05% This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft)...

Basics of an open pit mine

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...

Heap leaching

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems ,...

Uranium mining

Depending on the deposit, uranium is mined in one of three ways: open pit, underground, or in situ recovery Open pit When uranium is found near the surface - usually no more than 100 meters deep - it can be extracted via open pit mining In this method, soil and waste rock is removed by heavy equipment, allowing the ore to be accessed...
