Although over 75% of the gold used every year is made into jewelry, there are other uses. Gold is very flexible and is used in many industries for various purposes, depending on the purity. Many industries use gold for jewelry-making all the way to food applications.
Coins/bullion: Currency is one of the greatest uses as gold will always hold value even if the dollar collapses. Take American Buffalo coins, for example; they are 24K gold, pure as pure can be!
Computers/technology: Since gold is a terrific conductor of electricity, it is often found in computers and technology. You will even find small amounts in cell phones, about $.50 worth!
Aerospace: Being such a great conductor, various circuit boards for spacecrafts use gold as a shield to keep the temperature of the spacecraft stable.
Dental: We’ve all seen rappers with golden grills. Gold is not just for looks though! It’s highly useful in the mouth and can be found in fillings, crowns, bridges and other dental applications.
Medical: Not only is gold used in medical appliances and instruments, but it is also literally used as a “drug” for medical purposes for various conditions, including radiation treatment for certain types of cancer!
