Humans have been making use of gold since practically the dawn of civilization — as far back as 4000 B.C., the metal was used to make decorative objects, according to the National Mining Association. Since then, gold has come a long way, finding uses in modern medicine and mobile technology.
This precious metal has historically been used as a symbol of luxury, superiority and wealth. Besides jewellery, gold is used to increase the value of a huge range of decorative items, such as medals and badges.
The jewelry industry accounted for a 36.83 percent share of global gold demand in 2020, which amounted to about 1,400.8 metric tons. Jewelry was the largest gold demanding industry worldwide in most recent years, but was the second after investment demand in 2020.
Iron is used to make alloy steels like carbon steels with additives such as nickel, chromium, vanadium, tungsten, and manganese. These are used to make bridges, electricity pylons, bicycle chains, cutting tools and rifle barrels. Cast iron contains 3–5% carbon. It is used for pipes, valves, and pumps.
Smartphones contain about 60 different elements – including not only gold but copper and silver too. All three are good conductors of electricity, and circuits usually receive a thin covering of gold because it doesn’t corrode and so ensures a durable connection.
Gold-bearing circuit boards are increasingly used in appliances like microwaves, air conditioners, refrigerators, and kitchen stoves. A good rule of thumb is: The more technological features that an appliance has, the more likely it is to contain small amounts of gold.
