IntroductionWhat is mining?Mining is the extraction of minerals, metals and other materials from earth.
Mining of stone and metal has been done since pre-historic times.
Minerals are a nonrenewable resource, and because of this, the life of mines is finite.
Mining around the world
Environmental impacts
- Habitat modification.
- Changes in topography and landscape.
- Surface and groundwater contamination.
- High levels of residues.
- Fugitive dust emissions.
- Changes in land - use and soil management.
