I'll just create a list of what I know including their advantages and disadvantages. Hopefully somebody can chime in to help me with what I'm looking for.
1- Cementation by copper
+fastest process, easy to wash as most nitrates are water soluble, easy to melt
-copper will be the contaminant along with anything below the copper series, copper price will be significant when processing large lots
2- Silver chloride - HCl/Salt NaOH glucose
+little to no contaminant if done properly
-lots of steps, will require breaking of the chlorides/oxides to very fine powder for it to be successfully converted to metal, washing is also a problem
3-Silver chloride - HCl/Salt iron sulfuric
+faster compared to the 2nd option
-contaminant is mainly iron, washing is tricky because if you increase the pH to about 5 or more you will precipitate iron hydroxide, iron will also drop other base metals if silver chloride was not washed well.
Is there an easier way? I process about 2kg of silver in a week using paint buckets, I use option three and I do the tumbling manually :lol:
