One of the most expensive noble metals known to mankind is silver (Ag). Mining is the major method for obtaining silver. Apart from mining, a potential source for silver recovery is possible from radiographic waste films as well. The waste photographic films, X-ray contains 1-2% (worldwide) black metallic silver which can be recovered and reused. Methods for recovery of silver from x-ray waste include Chemical Precipitation, Electrolysis, Metal replacement cartridges, Biological method by enzyme production and extraction of silver by glucose, Electrolysis Process. In our project, silver from the used radiography films was recovered by Leaching and Precipitation. This method is one of the most efficient processes while compared to other methods of extracting silver from waste radiographic films. The photographic film was initially leached, Precipitated and heated to get silver metal. The resulting silver then had to have several stages of purification. The method was efficient and environmentally friendly to obtain silver compared to other methods.
