Openpit mines are characteristically engorged until either the mineral resource is exhausted, or a mounting ratio of overburden to ore makes more mining uneconomic. When this occurs, the exhausted mines are at times converted to landfills for disposal of solid wastes.
openpit mining Mining. a method of mining in which the surface excavation is open for the duration of mining activity, employed to remove ores and minerals near the surface by first removing the waste or overburden and then breaking and loading the ore.
Openpit mining. Openpit mining is probably most advanced because of developments in mining lowgrade copper deposits and iron ore. It is suitable for much of the resource if it is done on a large scale and will allow lowcost removal of most of the resource.

Open pit mines can be used in coal mining, and they are used extensively in quot;hard rockquot; 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.
Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow. This form of mining differs from
