How to Use Bleach on Gold Ore to Remove Gold | Sciencing

 · Gold is an almost nonreactive 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. This was the first commercial method used for gold ...

Electrorefining requires a much lower voltage than electrowinning and much higher concentrations of dissolved gold in heated hydrochloric acid media. Current densities in electrorefining are many times higher than in electrowinning. As an alternative to the Miller chlorination process, gold dore or other impure gold can be leached in chlorine–chloride media. The leached gold is then ...

Electrowinning refers to the process of using electrolysis to extract a metallic element from the compounds in its ore. Copper occurs on Earth both as native copper (the uncombined element, Cu), and in ores (copper compounds, or mixtures of compounds, from which copper metal can be extracted profitably). Copper ores are usually copper oxides, copper sulfides or copper carbonates. Most copper ...
