There are various ways to separate and recover gold, depending upon the nature of the ore. When gold occurs in a relatively coarse, free state, it can be recovered by mechanical means such as gravity traps and shaking tables, where the gold separates out because of its high specific gravity. Cyanidation is a chemical process used to recover gold th...
Gold is found across the Canadian Shield, in British Columbia and Nunavut, and on the island of Newfoundland. It was first discovered in Canada in 1823 along the shores of the Rivière Chaudière in the Eastern Townships of Québec. In 1858, following the famous rushes in California and Australia, gold was discovered in the sands of the Fraser River i...
The first to prospect and mine in North America were Aboriginal peoples who used minerals, including gold, copper, silver and cobalt, for tools, weapons, art and other objects. They discovered gold throughout the Pacific northwest and their attempts to defend their claims led to the Fraser Canyon War of 1858 and the formation of Indian reserves in ...
Canada's mining industry is expending tremendous effort to overcome a long history of environmental damage. One example of mining's environmental impact is gold mining's release of thousands of tonnes of toxic mercury and cyanide into the environment. In 2004, the Mining Association of Canada (MAC) began promoting a program called "Towards Sustaina...

North Carolina was the site of the first gold rush in the United States, following the discovery of a 17-pound (7.7 kg) gold nugget by 12-year-old Conrad Reed in a creek at his father's farm in 1799. The Reed Gold Mine , southwest of Georgeville in Cabarrus County, North Carolina produced about 50,000 troy ounces (1,600 kg) of gold from lode and placer deposits.

The east coast states are more populated, so it would make sense more gold deposits where found. I read theories that gold was formed from stars going nova after the big bang. Prior to Earth's final formation these now ancient meteors/asteroids deposited gold all over the world. Gold would be found closet to the Earth's core. As gold is a heavy ...
