Open cast mining is used in situation where the minerals are relatively shallow or less concentratedUnderground mining is used for deposits at greater depth higher grade deposits or vein oresUnderground mining is more expensive but less environmentally destructive.
Openpit mining is a method in which an ore is removed by digging a pit in the ground and is used to remove copper gold iron as well as nonmetallic minerals.
There are basically two types of mining i surface mining in this type of mining the minerals or rocks that are to be mined are exposed at the surface or very close to the surface.
There are two types of room and pillar mining–conventional mining and continuous miningConventional mining is the oldest method and accounts for only about 12 of underground coal output.
Underground mines are more expensive and often used to reach deposits that are deeperSurface mines are usually used for deposits that are shallower and less valuablePlacer mining is used in river channels beach sands or other environments to sift valuable metals from sediments.
