Recovering precious metals, esp. gold, involves highly toxic and dangerous chemicals like potassium cyanide and Aqua Regia (a mixture of concentrated Nitric and Hydrochloric acid).
A more low tech approach would be to use a smelting furnace to melt the gold off. However, in some countries, it is illegal for anyone who is not suitably licensed and qualified to attempt this.
In South Africa it is illegal for anyone other than a licensed jeweller to have raw and unprocessed gold in their possession.

The word 'gold' is from the old English word, 'gold'. This word was taken from the really old German word, 'gulth', which most likely meant 'pretty and yellow'. The Latin scientists used the word, 'Aurum' for gold. It is for this reason that the chemical abbreviation for gold is "Au".
Is there a difference between old gold and new gold?
From what I have been told, "new" gold is considered more "pricey" because of the craftsmanship involved in designing that piece of gold. "Old" gold is considered to be less in value - like buying a new car and then buying the same one that is a couple of years old. When buying an "old" piece of gold, the original owner paid for the craftsmanship and design. The only way for some gold to retain more of its original value is if it has a name like Tiffanys.
