Introduction Of Gold Mining Process

Heavy equipment is used to extract gold in underground mines such as the Campbell mine in Ontario, Canada. After the rock containing gold is removed from the mine, it is ground into dust in a crusher. Several methods have been developed to remove the gold from this dust. In the past, mercury trapped the gold by forming an amalgam. However, mercury is extremely poisonous
