When gold was mined in Nova Scotia in the late 1800s and early 1900s, crushed rock was spread over liquid mercury. Gold particulates stick to the mercury, so the gold-bearing mercury could be easily separated from crushed rock. The mercury could then be evaporated, leaving the gold. Theremaining crushed rock as a sand-like substance known as tailings. It was typically dumped into low-lying areas of lakes and streams near the mine. The mercury was recovered for reuse, but some was lost through spills and has accumulated in the tailings. (Nova Scotia Environment)
