Open-pit mining - Wikipedia

Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks ...

Open Pit Mines, Southern Arizona - NASA

The Bingham Canyon Mine is one of the largest open-pit mines in the world, measuring over 4 kilometers wide and 1,200 meters deep. Mining first began in Bingham Canyon in the late nineteenth century, when shafts were sunk to remove gold, silver, and lead deposits that played out by the early 1900s. It would take the advent of open-pit mining in 1899 to turn the Bingham copper deposit into

Opencast Mining - an overview ScienceDirect Topics

The open-pit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can ...
