AgCl to Ag using Al

AgCl to Ag using Al

I’m trying to figure out an effective way to chemically separate Ag from AgCl. Currently I’m experimenting with aluminum. I’m running into an issue with the Ag forming a shell around around untreated AgCl. This is how the boss wants it done but I’m struggling to make it work.
The current process is removing Ag from nitric acid using HCl, rinsing and collecting the AgCl. Placing 50lbs of the AgCl into a cement mixer and adding water. Once blended slowly adding fine aluminum until roughly 2.5 pounds has been added, always keeping the temperature below 120 F. If anyone has any tips, tricks, or completely new processes I’m open to all suggestions.
