Clean free gold from primary unoxidized ores is bright and clean and if brought into contact with clean mercury amalgamates readily and quickly Gold from oxidized ores on the other hand is almost invariably TARNISHED lightly filmed with a non gold bearing film and frequently COATED rusty with a heavy film in which oxides of iron are an important part.
22 07 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
