Extracting Gold HowStuffWorks
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.

Leaching Process - Chemistry of Extracting Substances
An example of the leaching process would be the leaching of Al 2 O 3.2H 2 O (or bauxite) with a heated and concentrated solution of sodium hydroxide. In this example, the concentrated NaOH dissolves the aluminium present in the bauxite whereas the impurities such as Fe 2 O 3 , TiO 2 , and SiO 2, are not dissolved by the reagent.

How to Use Bleach on Gold Ore to Remove Gold
2017-4-24 Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
