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 In a hard rock mine the bottom of the pit would be the

Opencast Mining an overview ScienceDirect

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 sustain There are many advantages in open pit mining method
