Gold Smelting Refining Process
Cu: Hg: Zn: Pb: SiO 2: FeS 2: Al 2 O 3: Melting point, o C: 1063: 960: 108139: 419: 327: 1725: 1170: 2075 : Alloys based on the goldsilvercopper system can be employed for many applications. They can be rolled, flattened and stamped easily. It has been investigated the effect of different elements and compounds on gold bullion properties. For example, deoxidizers are added in order to
