Processing, smelting and refining gold World Gold Council

In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore

Prospecting and Mining Gold HowStuffWorks

The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. But the search today is more systematic and precise. First, geologists know more about how gold

Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
