15/12/2010  Tailings containment facilities are regarded as the world's largest man-made objects. Terminology. Mine tailings' size and composition depends on the mining method. For hardrock metal mines, tailings are usually a very fine mud or powder, which is left over after ore is crushed and valuable minerals are extracted from it. Tailings may also contain chemicals used for mineral extraction.

From Tailings to Treasure? Miners Make Money

07/05/2015  Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts.org, another strategy is to produce thickened tailings, which are pressed or have chemicals added to remove excess water. Thickened tailings can be mixed with cement and used in construction or as backfill in underground mines.
