JEE : Electrolytic Refining
Therefore, electrolytic refining plays a vital role in refining metals using electrolysis. In electro-refining, impure metal is made anode, and pure metal is made as a cathode. The anode is the place or electrode where oxidation takes place, or loss of electrons takes place, and the cathode is the place or electrode where reduction or gain of ...
How is Silver Refined?
This process uses zinc which is later removed from the slag. The remaining high-grade silver will still need further refining to meet a target purity of 99.9% fine. Electrochemical Methods for Refining Silver . Electrolysis uses an electric current, a silver anode, and a low-acidity electrolyte to deposit pure silver crystals on a silver …

High purity submicron size silver metal and zinc oxide was prepared using a new recycling process from silver oxide batteries which is already used in many kind of small devices. It is well known that the recycling of battery waste residues not only protects the environment but also improves the recycling economy considerably.
Zinc refining
Zinc refining is the process of purifying zinc to special high grade (SHG) zinc, which is at least 99.995% pure. [1] This process is not usually required when smelting of zinc is done through electrolysis processes, but is needed when zinc is produced by pyrometallurgical processes, because it is only 98.5% pure. ...
