Quick Summary

Mining is the process of extracting valuable minerals from the Earth's surface. Minerals are naturally occurring inorganic substances with a defined chemical composition and physical properties, though coal is often included. Ore refers to metalliferous minerals or aggregates that can be mined profitably.1

Area mining is a type of strip mining used for near-surface, flat-lying deposits. It involves creating parallel trenches, or strips, to remove overburden and expose the mineral seam. The overburden from new cuts is used to fill the voids of previous ones. This method is suitable for minerals like coal and phosphate. Reclamation of the land is a standard part of modern mining operations.23
