Historic Gold Mine Tailings Nova Scotia

2009-9-4  Historic Gold Mine Tailings FAQ 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.

Biological effects of gold mine tailings on the intertidal

2017-1-15  1. Introduction. Nova Scotia experienced its first gold rush in the 1860s after the discovery of gold in a quartz vein at Mooseland in 1858 (Bates, 1987).This was followed by two additional gold rushes which accounted for the development of > 60 gold districts throughout Nova Scotia from the 1860s to the mid 1900s.During this time, total gold production for Nova Scotia was estimated to be 1.2 MOZ.

Biological effects of gold mine tailings on the intertidal

From 1861 to the 1940s, gold was produced from 64 mining districts in Nova Scotia, where mercury amalgamation was the dominant method for the extraction of gold from ore until the 1880s. As a result, wastes (tailings) from the milling process were contaminated by mercury and were high in naturally occurring arsenic.

Consequences of Historical Mining Gold a Nova Scotia

Cyanide was also used to extract gold in historical mining. If cyanide leaks into the environment, its impact is immediate and lethal to people and wildlife. Cyanide does degrade over time, unlike arsenic and mercury, and despite testing, none has been found in the tailings in Nova Scotia. Abandoned Mine

Gold was mined in 64 districts in southern Nova Scotia between 1861 and the early 1940s, followed by limited, intermittent production up to the present. There is extensive dispersion of arsenic- and mercury-bearing mine tailings in the receiving environment downstream from many of these sites. Elevated mercury concentrations, highest near old stamp mill foundations, occur because of the
