Mine tailings (the ore waste of mines typically in the form of a mud-like material) originate from both coastal and land-based mining activities and can be disposed of in the marine environment. These mine tailings disposals are known as "submarine tailing disposal" in shallow waters, and "deep sea tailings disposal" in deeper waters (Vare et al. 2018).
