It can take 10-20 years from the discovery of a gold deposit to the development of a mine. Production could last from several years to many decades. Gold mines still have a lot of work to do. No one knows for sure how much gold is left underground, but one Goldman Sachs analyst says there's enough to mine for the next 20 years.

The Refining Process. Refiners start with one of two types of gold: a doré bar or scrap. Doré bars are produced by miners and are about 80 percent pure. Refiners increase the purity by separating the other precious metals and less precious metals that are mined with it. Using induction heating, doré bars and scrap are turned into molten metal.

This invention is a method for recovering gold from a refractory sulfidic gold-containing ore by oxidizing a slurry of the ore. Oxygenation occurs in an autoclave at between about 400° F. and about 500° F. with an oxygen overpressure of between about 50 psig and about 100 psig for at least 2 hours.

But if the gold price rises by 20% to $1,200 the mine will make $400,000,000 overall. This demonstrates a 'gearing' effect of 4 times - i.e. for a rise in bullion of 20% the share will rise by the 20% plus another 4 times 20%, i.e. 100% (all other things being equal, which they rarely are).
