how would you use aluminum to extract silver from film?just ideas please
The silver in film is part of a silver salt (silver halides.) It is a very very small amount, probably less than 1 cent worth per roll. You would be a lot better off selling the film than trying to extract the silver from it. If you are hell bent on it, the first step is to expose the film to light. This will break the silver from the halides. Then you can go about trying to figure out how to get the silver apart from the film. I am sure it is possible, but it would involve a lot of work. I imagine you you would spend about $100 on ever $1 worth of silver you could extract.
