Gold - coveted by many
Gold’s qualities make it one of the most coveted metals in the world. Not only can it be beautifully shaped and sculpted, the yellow metal conducts electricity and does not tarnish. These qualities make it the metal of choice for a wide variety of industries. Let’s take a look at some industrial, medical and technological uses of gold, some of which are truly amazing.

Gold is not toxic
Thousands of years later gold is still being used for fillings, crowns, bridges and orthodontic appliances. Gold is a bio-compatible metal, meaning it can be placed in contact with a person’s body and not cause harm to one’s health. Pic: AP Photo/Franklin Reyes

How much gold is in your mobile?
According to the World Gold Council, a single mobile device contains up to 50 milligrams of gold. That’s a tiny amount but nearly 1 billion cell phones are produced each year. With a gold value of about 38 cent in each phone, that adds up to €384 million dollars in gold each year. Pic: Julien Behal/PA Wire
Gold is found in most computers
Gold can also be found in most standard desktop and laptop computers. The precious metal is used in a CPU’s memory chip and motherboard, allowing parts of your computer to receive power and communicate with each other. Pic: AP Photo/Jerome Favre
Gold has been used in medicine for 4,500 years
The earliest medical use of gold can be traced back to China in 2500 BC. Chinese physicians used pure gold to treat furuncles, smallpox, skin ulcers and to remove mercury from skin and flesh, says GoldBulletin. Pic: CP PHOTO - Steve White
Nowadays, it's used to treat arthritis
Today the metal is primarily used to treat patients with arthritis. Gold salts are used to reduce swelling, bone damage and to relieve joint pain and stiffness. It’s a slow process; patients generally receive 22 weeks of gold injections before experiencing relief. Pic: AP Photo/Reed Saxon
Gold can be flattened into extremely thin sheets
Gold is highly malleable and flexible. Gold can be beaten into thin sheets, only a few millionths of an inch thick. These sheets, known as gold leaf, are displayed on buildings throughout the world, such as St. Michael’s Cathedral in Kiev, Ukraine. Pic: AP Photo/Sergei Chuzavkov

Gold is used in space...
It’s truly a gold universe. Space vehicles are fitted with gold-coated polyester film to reflect infrared radiation and to help stabilize core temperatures, says Geology.com. Without gold, darker colored parts of spacecraft would absorb significant amounts of heat. Pic: US Funds
It's also found in space suits
NASA also protects its astronauts using gold. Astronauts’ helmets are covered by the extravehicular visor assembly. The visor is coated with a thin layer of gold to filter out the sun’s harmful rays, according to NASA. Pic: AP Photo/Paul Sancya
