Gold mining is the resource extraction of gold by mining. As of 2016, the world's largest gold producer was China with 463.7 tonnes. The second-largest producer, Australia, mined 287.3 tonnes in the same year, followed by Russia with 274.4 tonnes.
The use of electricity is one of the latest methods used for purifying gold. This process is commonly referred to as the Wohlwill process. Using this method, the impure gold is placed in a solution made up of gold chloride and hydrochloric acid. Then, electric current is passed through that solution to remove the impurities from the gold.
