Historic Gold Mine Tailings novascotia.ca

Gold mine tailings are the by-product of a mining process used in the 1800s and early 1900s in Nova Scotia and many other areas. The tailings contain arsenic and mercury. They are generally in remote locations. Some are located near people. Most Nova Scotians are probably never exposed to tailings. People who live near them may have some exposure, depending on their activities. There is no

Historic Gold Mine Tailings in Nova Scotia G E O S C I E N

Gold Mine Tailings in Nova Scotia J. Drage Introduction Historic gold mining in Nova Scotia produced over 3 million tonnes (t) of tailings (Parsons et al., 2012). During this period, no environmental regulations were in place and tailings were commonly discharged into streams, ponds, rivers, wetlands and surface depressions. This resulted in the formation of tailings flats that can measure up

In 2018, Atlantic Gold spent over $21 million on environmental efforts at Moose River, which included initial efforts that led to the clean-up of over 50,000 tonnes of contaminated residual material that were the remains from mining conducted in the 1800’s and early 1900’s, better known as historic tailings.

Consequences of Historical Mining Gold a Nova Scotia

The gold-bearing rocks in Nova Scotia contain naturally high amounts of a mineral called arsenopyrite, which bears arsenic. Any activity that disturbs arsenopyrite-bearing rocks could result in releasing more arsenic into the environment. The production of waste rock piles and tailings only served to further concentrate the already abundant arsenic. Arsenic can cause digestive issues, cancer

In the hard rock gold mines of Nova Scotia, the gold is extracted from the ore first by pulverizing the rock and then using chemicals to remove the gold from the other minerals. Mercury. Once the ore is crushed into fine sand by the stamp mills it is flushed down a copper plate that is coated with a thin film of mercury on the surface. Diagram showing mercury-gold extraction process.

Mineralogy and spectral reflectance of soils and tailings

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

Gold in Nova Scotia Mining Technology

None of Nova Scotia’s gold deposits are considered ‘mined out’ by mining industry standards. The province’s historic gold mining activities were limited to veins near the surface. In only a few mines, the workings went below 200 metres, a depth considered shallow in today’s mining.

Gold mining in Nova Scotia

Gold mining has been a part of Nova Scotia's heritage for 150 plus years and continues to this day. Over a million ounces of gold have been produced in the province since mining began in 1861. Although not as well known as the gold rushes of California, the Klondike, Australia, and South Africa, three distinct rushes resulted in an economic boom in the province and saw the birth and sometimes
