Does Real Gold Tarnish?

When your gold jewelry tarnishes, it doesn't mean that it's not real gold; it is not just pure gold or 24 karat gold. Real gold jewelry can eventually tarnish. There are even rare circumstances in which jewelry containing high karats of gold have tarnished but by and large the higher the percentage of gold in the alloy, the less likely that the gold piece will tarnish.

Processing, smelting and refining gold

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 and solvent in large tanks equipped with agitators.
