- ABSTRACT. Photographic waste is one of the wastes produced by the paper and printing industries. Photographic waste usually contains metal ions mostly silver, sodium, potassium and iron. Since silver is photosensitivity material and its valuable increasing price, people tends to recover the silver from photographic waste to reuse it in paper and printing industries.
Electrolytic Silver Recovery - Industrial Wastes

- Electrolysis, or more specifically electrowinning, is the most widely used and universally applicable method for silver recovery in the photoprocessing industry. An electrolytic silverrecovery cell consists of a cathode and an anode. Oxidation occurs at the anode (positive electrode) and reduction at the cathode (negative electrode).
