From Tailings to Treasure? Miners Make Money

2015-5-7  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, 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.

Historic Gold Mine Tailings - Nova Scotia

2009-9-4  What are gold mine tailings? Tailings are a by-product of a gold mining process that was common in the late 1800s and early 1900s. Gold-bearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold. The remaining sand-like substance, known as tailings ...
