Calculating amps for square inch of anode
« on: May 27, 2020, 09:33:08 PM »
I understand that Kep indicated that one could process silver using 10 mA per square inch. So if my anode had 6 square inches on one side does that mean that for two sides I would have 12 square inches and therefore I conceivably apply 120 mA and produce good Colloidal Silver? TIA

The side of the anode pointing toward the cathode counts. The back side not nearly as much.

I can't say I've ever seen anyone running more than about 20ma with a 1ozt silver bullion bar though But then that doesn't have 6 sq-in surface area on a side so you have to be talking about a larger bullion bar, right?

Even if you can, at high currents like that you may well need a stirrer and for sure would need to process at a higher temp (I assume you're talking about higher than 20PPM - I can't say if you could do 20PPM cold at that high a current).

Definitely recommend a stirrer for higher ppm and currents.
