I have alot of silver that I want to process in an electrolytic cell (over a pound of dried, cemented silver powder).
Your DVD "Silver, A to Z" gives specific directions for a 1000 ml cell.
Would it be possible to increase the volume to 2000 ml by just doubling the amount of electrolyte - ie, 200 grams silver powder, 234 ml nitric acid, and then enough distilled water to bring the total volume up to 2000 ml in a 2000 ml container?
By making the cell larger, I could made the anode basket & filter bigger and install more anodes - plus reduce the amount of time harvesting & cleaning the cell.
Also, I am going to use cememnted silver for the electrolyte. First I will boil the cememnted silver in Hydrochloric acid to remove impurities. Then I will dissolve the cememted silver in nitric acid. Then filter to remove gold or platinum that may be present and then proceeed with the cell construction.
I also want to remove any lead or tin that may have made it into my cememnted silver. Is there a process for doing this?
When harvesting the silver crystals from the cell, I plan on filtering the electrolyte. But I will not let the silver crystals make it into the filter.
Instead I will leave the crystals in the container after pouring off the electrolyte into the filter. To remove any electrolye still clinging to the crystals, I will wash the crystals over and over in boiling water, pouring the water off each time, into a filter paper if necessary, but not letting any of the crystals enter the filter paper. Then dry and melt.
Please correct me if I have made any errors to the above process.
Thanks so much for your help.
