Reserve - known deposit worth mining
Open pit mines, quarries
Explosives are often used
Remove large amounts of material
Resources are located too deep for surface mining
Vertical shafts can be used to connect to passages that are cut horizontally or an angle
Reclamation
Land used for mining must be returned to its original state

Required by law since 1970's
Processing and Refinement
Once the ore has been extracted it needs to be refined so that it can be made ready for use.
Metals
Nonmetals
need extensive processing and refinement
usually less plentiful
higher value and cost
need less processing and refinement
