An Overview of the Open Pit Mining Process ...

Mar 02, 2016  Open-pit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is []

Open Pit Mining - an overview ScienceDirect Topics

8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

Basics of an open pit mine - Mine Engineer.Com

The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine’s life." To expose and mine the ore, it is generally necessary to excavate and relocate large quantities of waste rock.
