Seeing In Gold

 

• The symbol of the metal originates from the Latin word for gold called aurum 

There are no records of gold’s actual year of discovery since it existed during the prehistoric times in the form of nuggets in river and stream beds. In 2000 BC, the Egyptians actively mined the metal that was obvious from the objects found in the graves of the royal family.

By 640 BC, gold coins made by alloying Au with silver began to circulate in the Kingdom of Lydia. It was only during the reign of King Croesus when pure coins were minted

Every year about 1500 tonnes of gold are mined of which two-thirds comes from South Africa and Russia
