The true cost of producing an ounce of gold

May 23, 2017As you can see, the cost of mining gold goes well beyond the act of pulling the metal from the ground. Fortunately, more than one-third of gold is recycled from old jewelry, electronics, dentistry, etc. This means that not all consumables made with gold must rely solely on gold that has been freshly sourced from the ground.

Rcovery of gold in pyritic ores

In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores.

Gold Mining Methods

Summary. Historically, the majority of gold was mined from placer deposits, where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock outcrops.Some early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited it over thousands of years.
