To test if a rock has gold, rubbing the rock and smelling it can be informative. Gold doesn't have a smell, but pyrite, often confused with gold, smells like rotten eggs due to its sulfur content. This method is easy and doesn't damage the rock, but it won't differentiate gold from mica, which also doesn't have an odor.
Amalgamation, which uses mercury and gold particles to form an amalgam, is often used in small-scale mining operations. This type of ore is generally processed by flotation, which concentrates the gold in the non-ferrous ore concentrate and then recovers the gold during the smelting process.
In addition, the application of flotation and other methods of concentration to gold ores followed by cyanidation of the product thus obtained not only concentrate the gold but also frequently concentrate the detrimental impurities. The net result is the complication of the chemistry involved in the cyanide process.
