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 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

After the obtained gold slime is simply pickled to remove impurities, the gold ingot can be directly smelted. What’s more, the new process of electrowinning of gold has the following advantages:
The gold is mixed with the sodium cyanide which leads to the following Elsener’s equation and reaction. This is done to make soluble gold; Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of
