Surface Mining

Surface mining is done by removing (stripping) surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits. Techniques of surface mining include:
- Open-pit mining, which is the recovery of materials from an open pit in the ground
- Quarrying, identical to open-pit mining except that it refers to sand, stone and clay
- Strip mining, which consists of stripping surface layers off to reveal ore/seams underneath
- Mountaintop removal, commonly associated with coal mining, which involves taking the top of a mountain off to reach ore deposits at depth.
- Landfill mining involves sites where landfills are excavated and processed.
