Gold,which has been prized for it’s natural beauty, to some may be a symbol of ones relationship or a token of another’s affection for them. Gold, however is much more than that. The earliest known history of gold and humans is believed, according to archealogical digs began in the Middle East, where the first known civilizations began.
Throughout history it has been a symbol of riches and wealth and a definate source of greed. But more specifically it is a precious and one of the heaviest metals known to man. And it’s ability for withstanding even the most corrosive elements has made it well suited for use in coins and jewelery. The most purest form of gold is of course 24 karat.
How gold is recovered?
The most common methods of recovering gold are mining or panning. Mining can be traced as far back as 3500 B.C. It is the process of recovering gold from the earth by local laborers who use special tools and equipment. Panning is a mostly manual technique where in a shallow pan filled with the sand and gravel collected which may contain gold are submerged in water and sifted untill only the gold remains.
The panning material is collected from stream beds. Panning sites are usually marketed as tourist attractions, where they are open to the public, allowing visitors to pan for they’re own gold. There are also several other methods such as metal detecting, in which a person simply walks over an area using a metal detector that can scan below the surface, this method is highly popular among “Gold Diggers” due to the fact that this device is highly mobile and easy to operate and with it’s powerful sensors, can scan for metals at least a meter below the surface.
Among several other countries, gold deposits are located in several states in the U.S including Arizona, Colorado, California, Washington, Nevada, montana and South Dakota. Ther are two types of gold deposits 1. Lode deposits, which are generally extracted by drilling or blasting. 2. Placer deposits, which require hydraulic mining or panning. After the gold is recovered and separated it is ready to be refined.
How is gold refined?
After the gold is seperated from the ore it is ready for refining. There are four main processes in refining gold which are floatation, amalgamation, cyanidation, and carbon- in- pulp. The process used depends on the initial grinding of the gold ore. All of which are combined with chemicals and solutions to extract the gold.
Since gold is very malleable and ductile it can be alloyed with other metals such as silver, copper, platinum or nickel, to form coins and jewelery. A karat is a unit equal to 1/24 of gold in an alloy and measured by it’s purity, so 24 karat is pure gold while 18 karats are 18 parts gold and 6 parts other types of metals.
How is gold melted and manufactured?
Gold bars are produced directly from gold that has been melted down in bulk in a large holding crucible in an induction furnace. It is then poured into a preheated transfer crucible, after this process the melted gold is then poured into the sized cast-iron bar moulds.
After the moulds have been poured they are immediately dropped into a tank of water for cooling. It is then cleaned and weighed, then marked with the weight and stamp of the refiner and the purity of that batch of gold along with a serial number. They are then ready for distribution.
Making gold into jewlery.
Gold, throughout history has generally been used for monetary exchange, and has been used to honor the rich and powerful namely royalty, however, today it is generally used for making jewlery, and luxury items. The gold is usually used with base metals in the making of jewlery due to the fact that it is so soft, in it’s purest form it would bend and be difficult to work with.
Though there are several methods used in jewlery making, the most common method used is the ” lost wax” casting method. The object to be created is first sculpted in wax, when the wax scupture is completed it is encased in plaster, after it has hardened an dried it is then put into a kiln or oven this will cause the wax to melt, leaving the hollow image inside, it is then put into a casting device that will use force to drive the gold down where it will fill the hollow spot, it is then broken to reveal the piece of gold jewlery where the sculture once was. It is now ready to be cleaned, polished and ready for show.
