Did you know about Gold?

• The world’s largest gold producing region, the Witwatersrand in South Africa, was discovered by an Australian prospector, George Harrison, who was working on a farm in South Africa in 1886. He tripped over a rock outcrop and, on closer investigation, found gold in the rock. He made a claim but later sold it for £10.
• It is estimated the amount of gold extracted from 50,000 mobile phones is the same as that extracted from 110 tonnes of ore.The Minoans of Ancient Crete created the first gold cable chains – jewellery chains made from a series of links – between about 1900 BC and 1200 BC.

• Mercury was once used to extract gold from ore, a process that was used for centuries, at least since the time of the ancient Egyptians. Ancient Andeans are also believed to have known how to use mercury to extract gold
