G 0 L D OLD most famous of all metals, is the first element G mentioned in the Old Testament: As a material for ornaments, it was used in Egypt as early as the Stone Age. As a medium of exchange; it was in use centuries before the time of Croesus-the proverbially rich King, of Lydia who, in the Gth century B.C., minted the earliest known gold coins: Although today gold is seldom used for coinage, most currencies are still backed by gold, and nearly two-thirds of the world s present gold stock is held for this purpose in the vaults of national banks. Gold is widely distributed in nature-but only in Africa, the Americas, Australia and Russia is it found in large quantities_ A heavy, untarnishable metal, gold is too soft and malleable for most practical purposes_ Alloyed with other metals however, it is well known in jewellery and in the form of gold leaf. Because of its outstanding resistance to corrosion, gold is also used in dentistry and in the manu- facture of electrical contacts and laboratory apparatus. Compounds of gold are sometimes used in medicine and photo- graphy. To extract gold from its ores the method most widely employed is the cyanide process. Discovered in Great Britain in 1887 , this process enabled the world $ gold output to be trebled within 20 years. ICI: makes large quantities of sodium cyanide for gold extraction.
