Open Pit Mining IntechOpen

2021-2-17  Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main topics that will be discussed in this chapter will include

Open Pit Mining an overview ScienceDirect Topics

Large, low-grade ore deposits are usually economically attractive because it permits high recovery of the resource and allows sufficient space for large and efficient mining equipment. An open pit mine could recover almost 90% of the oil shale in a very thick deposit [17]. It is said that strip mining could provide an even higher recovery.
