Read MoreWhat 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 ...
