Most sources highlight that it was in use in the ancient towns in Mesopotamia, such as Babylon, which is modern-day Syria. Heraclitus, a Greek philosopher, extensively wrote about gold smelting during the civilization of the Greek empire. ... The refining process aims to achieve a high gold purity parentage. The process includes cupellation ...
King Croesus' Gold begins with a prologue (Ramage and Craddock) introducing the reader to the Sardis excavation of the refinery, with a brief explanation of the processes involved in refining gold and silver, most notably cementation (a parting process that separates the silver from the gold in a gold-silver alloy) and cupellation (a …

Common impurities found in gold ore include silver, copper, iron, and sulphur. These impurities need to be separated and removed through various refining processes to obtain pure gold. Refining Process Steps to Follow. The initial step in the gold refinery process involves the extraction of gold ore from the ground.
The technique of smelting mined gold ore concentrates reported by Diodorus Siculus as being used in Egypt in the Second Century B.C. has been simulated in the laboratory. A considerable degree of refining was found, comparable with that yielded by the medieval process of cementation with salt, and with a negligible loss of gold.
Native gold and silver are very rare – they are usually found blended into lead ores. The cupellation process is one of the best ways to extract these precious metals. It starts with the construction of a cupel, a small bowl that will contain the alloyed metals throughout the process.
Gold, however, is routinely found in nature as an element unlike copper and iron, and most other metallic elements. Gold, although rare, can be found as flakes or nuggets. As shown in the illustration below from an ancient Egyptian tomb, the Egyptians used charcoal and blow pipes to reach the temperatures needed to melt gold.
In many cases, gold occurs in low-purity ore in the form of flecks or fine grains. Vast quantities of soil or sediment must be processed to find tiny quantities of gold. For situations like this, the first step in the refining process is physically separating the gold particles from the surrounding earth.
Gold processing includes ore preparation, extraction of valuable content, and refining of precious metals to obtain pure gold. Techniques vary based on the type and location of …
