The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed.
Pre-Melt. Prior to actually refining it, the impure gold is melted.
Chlorination. Injected into the molten metals is Chlorine gas, which forces all metals but gold to float.
Degolding. Once the molten chloride slag has been recovered from chlorination, soda ash is added.
Electrolysis. Through this process, gold is brought to 9999 purity.
Final pour.

How did they refine gold in biblical times
In emotional gold refining, the mined ore is crushed and ground into a powder that must then be washed, used, and refined frequently. During these washes, all unwanted non-metallic elements are largely removed; only sterling silver elements remained.
How did ancients make gold
Gold was first found on the surface near river plains in Asia Minor, such as Paktholos in Lydia, and from 2000 B.C. The Egyptians also mined underground, and then the Romans in Africa, Portugal and Spain. In addition, there is evidence that the molten Romans contained rare ore particles such as wrought iron pyrite.

How does fire purify gold
In an exciting process called refining, it is liquefied in a furnace and then soaked in large amounts of soda and borax. This effectively separates rare metal impurities and other metal strains. In fact, there are a number of interesting scientific and technological methods for refining gold.

What is the process of refining gold
The two most common refining methods used to obtain fine gold are the Miller operation and the Wollville operation. The Miller process uses chlorine gas to retain impurities when the gold runs out; melting impurities are released to some extent on the surface of the molten refined gold.
