Mercury
Do you know what kinds of chemicals are used to extract gold? In addition to sodium cyanide, mercury is also commonly used in gold ore recovery.
Mercury, which appears in liquid form at normal temperature, is highly volatile and chemically stable, and is neither soluble in acid nor alkali. Mercury has a long history of use and is widely used in the fields of medicine and electronics. Usually, thermometers are common in our daily lives. In addition, it can also extract gold from it's the ore. It has been the first choice for many gold ore dressing plants because of the advantages of lower cost, higher efficiency and convenient operation.
The principle of using mercury to extract gold (amalgamation method) is mainly that after the mercury is added to the slurry, the surface of the gold particles is wetted by mercury, and then the mercury diffuses into the interior of the gold particles, causing a chemical reaction. Au+2Hg=AuHg2. Finally, the solid of Au3 Hg will form. When the obtained solid matter is heated, the mercury will volatilize into an elemental form, and the gold will exist in the form of sponge gold. Mercury amalgamation is generally divided into two types, mainly internal mercury amalgamation method and external mercury amalgamation method.
