mining processes in an open cast mining

Opencast Mining - an overview ScienceDirect Topics

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.
