What is an example of mining waste?

An example of mining waste is tailings, which are the materials left over after the extraction of valuable minerals from ore. Tailings often consist of finely crushed rock, chemicals used in the extraction process, and water, and they can pose environmental hazards if not managed properly. Additionally, overburden, the soil and rock removed to access mineral deposits, is another form of mining waste that can lead to habitat destruction and soil erosion.
