Refining Gold Jewelry Scraps Ganoksin Jewelry Making

Gold of a purity of at least 98.5 percent is normally required for the anode, as too much silver will result in silver chloride building up on the anode surface and preventing dissolution of the gold. Typically, the input material for the anode is the gold from the Miller process, described previously.

Mercury Usage in Gold Mining and Why It Is a Problem

Jul 22, 2019 This process does not result in gold that is 100% pure, but it does eliminate the bulk of the impurities. The problem with this method is the release of the mercury vapor into the environment. Even if the equipment is used to catch the vapor, some still can get into the atmosphere. Mercury also can get into the soil and water if it still is ...
