Gold Mining in South Africa Africa Mining IQ

In 1975, South Africa was responsible for producing 40% of the gold ever mined. By 2010, however, China affirmed its status as the world’s largest gold producer with production of 324 tonnes of gold, followed by Australia (222.8 tonnes), and South Africa with 219.8 tonnes. Today, South Africa produces only 4.2% of the world’s gold.
