I am recovering some silver (about 3 troy ounces) from a batch of inquarted gold that I just completed. The silver dissolved into a nearly clear solution, but had some fine dark powder in it so I filtered that off.
The silver is cememnting out nicely with coils of 10 gauge clean copper wire suspended in the silver nitrate solution with string.
I have stirred the silver nitrate vigorously then filtered the nice new silver powder out and placed it in a corningware casserole to start drying.
Hoke, page 79, describes a process for ridding cemented silver of excess zinc. The zinc is from a DIFFERENT process than the one I am using.
Hoke says to mix up 1 part HCl to 15 parts water, and pour it over the cemented silver powder and watch for bubbles. When the bubbles stop on stirring, then wash well with clean hot water and allow the silver powder to dry.
Here is my question:
Can I, or should I, use this process on my cemented silver powder to further reduce any contamination of my cemented silver powder?
Is there any value to doing this, or is it just a wasted step?
Is there some other, more effective process to use to rid the silver powder of any contaminates?
I am just trying to get the purest silver I can with the method I am using (copper cementing).
I know the eltrolytic cell is the best way to get real pure silver - that is on my plate for the near future.
