My name is Michael Henderson and I live in Hesperia, CA. I have been doing research for the last few months on how to covert silver oxide batteries into elemental silver. Today, I came across this site and have spent the afternoon trying to develop a process. I came across Manuels post which, in addition to the general reactions list, set me on a path I would like to pursue. I do, however, have some questions specific to my situation that I hope someone can answer.
1. I live in Southern California and have been unable to locate a source for nitric acid, HCl, NH4OH or NaOH. Can someone offer guidance on where I might be able to aquire some locally?
2. The cells that I have were from a military spec battery used on aircraft and are very large. The primary metals are silver and zinc. I have opened them and have found that they seem to be composed of a grid like mesh with a blackish sludge. I'm assuming this material is the silver oxide. Would this assumption be correct or is the grid the silver, not the paste? How would I go about checking?
3. I wanted to make sure that I have the process correct before proceeding.
Dissolve in nitric acid --> add common talbe salt to precipitate out the Ag and Hg --> filter and wash the white ppt --> add aqueous ammonia to the white ppt to remove the Hg --> filter the liquid --> add HCl to the liquid to reform AgCl --> add NaOH --> wash and add karo syrup --> wash and filter
Any help with all of this would be wonderful.
