The largest physical disturbances at a mine site are the actual mine workings, such as open pits and the associated waste rock disposal areas. Mining facilities such as offices, shops, and mills, which occupy a small part of the disturbed area, are usually salvaged or demolished when the mine is closed.
Mining operations generally progress through four stages: (1) exploration, or the work involved in assessing the size, shape, location, and economic value of the deposit; (2) development, or the work of preparing access to the deposit so that the minerals can be
Ironrich rocks are found all over the world but the rocks are only oregrade and suited for commercial production in some countries. The limitations to iron ore mining are not because of the size or grade of the ore, but rather the costs associated with mining the ore and transporting it.
