· These eventually find their way, together with gold and silver, into the copper refinery anodic slimes (see Chapter 47). Most large copper refineries, therefore, normally operate a PM plant where anodic slimes are treated. The process used can vary from plant to plant. Processes used could be essentially pyrometallurgical in nature or a combination of pyrometallurgical and hydrometallurgical ...
Metals commonly alloyed with gold for jewelry purposes include: silver, copper, nickel, iron, zinc, tin, manganese, cadmium, and titanium. In addition to enhancing gold's strength, alloying changes some of its other properties, too. For example, some gold alloys stain skin or cause allergic reactions. The gold itself doesn't cause these reactions. Rather, the alloyed metals do. Wedding ...

The anode sludge will contain valuable metals such as silver and gold. Metals above copper in the electrochemical series (like zinc) will form ions at the anode and go into solution. However, they won't get discharged at the hode provided their concentration doesn't get too high. The concentration of ions like zinc will increase with time, and the concentration of the copper(II) ions in the ...
