Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner.

Quarrying is normally associated with the extraction of rock using opencast techniques and leaving large holes in the ground. 1km of motorway requires 125,000 tonnes of crushed stone. Mining can be opencast but more often involves digging tunnels below ground. Normally topsoil and underlying bedrock is removed (known as overburden) and stacked ...
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
