9. We don't need to see things to understand them. It is now generally understood that gold is formed in neutron star collisions.

Peru – 162.3 tonnes. Gold output fell for the second consecutive year in Peru, by 6 tonnes, largely due to crackdowns on illegal mining operations in the La Pampa region. Mining is a significant portion of Peru's economy and the nation is also number three in the world for copper production. 7. Indonesia – 154.3 tonnes.

Gold Mine Operation: This is the actual physical extraction of hopefully rich gold ore from the newly developed gold mine. Unrefined rock extracted from the gold mine requires further processing at a refinery in order to fully recover the potential gold deposit (and other valuable minerals such as copper, silver, etc.).

Gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. ... Discovered in 1886, it produced 25 percent of the world's gold by 1899 and 40 percent by 1985.
