Smelting gold . It is thought that gold has been smelted since 6000 BC; first done by the Babylonians, in current day Syria. Today, it is a highly sophisticated treatment process, but the fundamentals for smelting gold remain the same. In very simple terms, the first step in smelting gold is pulverising or crushing the ore.

Gold exploration in the lower layers of soil to get the primary sediment deposits began in 1860 with gold using a cyanide treatment system. And in 1960 the method of processing lowgrade gold began being applied, which carried out the processing system through leaching heap, this process is basically developed from gold processing system using cyanidation .
Smelting gold usually involves hightech and highcost tools to perform. Mostly, mining companies do the procedure, which sees one material bonded to or released from another in the presence of extreme heat. However, prospectors, and people at home, can smelt their old gold using some simple steps.
Jan 18, 2017#0183;#32;Gold smelting is a long process and involves a number of steps. Here are the major steps you should follow when smelting gold: 1. Gold Processing . The first step in gold smelting involves processing the gold ore. The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore
If the gold can not be concentrated for smelting, then it is leached by an aqueous solution: . The cyanide process is the industry standard.; Thiosulfate leaching has been proven to be effective on ores with high soluble copper values or ores which experience pregrobbing: the absorption by carbonaceous components which preferentially absorbs gold and goldcyanide complexes.
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis.
The smelting process removes impurities such as copper, iron and zinc while the refining process is necessary to extract precious metals like silver. Note that to remove impurities via smelting, a flux {oxidizing agent} is required. Gold smelting does not provide users with 99% pure gold. Obtaining 99% pure gold would require a refining process.

1/3/2019#0183;#32;Smelting gold is a popular choice for those with outdated gold jewelry that is mixed with other materials. Smelting gold is a technique for refining and shaping metals that has been in use for thousands of years. The discovery of this process marked the beginning of the Bronze Age as gold smelting was used for the creation of new weapons for war.
Gold processing Gold processing Refining: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more
