Every film either X-ray or photographic, has a thin coating of silver over it. During image formation, silver transfers from image portion of films and comes to the fixing solution called & 39;hypo fixer& 39;. Due to repetition of fixing process of several films in same solution, more and more silver keeps on dissolving in hypo fixer solution.
2 Can you please send me the details of Silver extraction from Hypo waste. 1.Now the in Studio Hypo is not used.

Electrolytic recovery is the most widely used silver recovery method for fixer solution and photographic processing solution. The silver is recovered from solution by electroplating it onto a hode. A controlled, direct electrical current is passed between two electrodes suspended in the silver-bearing solution.
