Silver crystal refining

[Yggdrasil]

What I was thinking was dropping out the copper from my electrolyte so that I could keep using it, instead of having to make it over each run and save on acid.

I was rinsing the silver crystals with distilled water over and over until the rinse water showed no color and nothing when treated with HCL.

You can't get the Copper out without taking the Silver first.

i do not know of a way to simply take out the copper, to free it up for re-use on silver. at least, not with out a lot of effort and cost. the only way i am capable of recovering the copper on my own, is to drop it out with a metal of higher reactivity. but even then, your nitric is just tied up with another metal in solution, and will not help you any more with silver refining.

4metals posted a video above of recovering your copper using fractional distillation. it is a very long and tedious and not as easy as the video shows. i'll also mention it is a very dangerous method. hot sulfuric acid is not a joke, and i do not recommend playing with it.

for all sensible solutions until you're a master chemist far beyond my ability, once the solution turns too blue (and you'll learn when that is after trial and error), you'll know it's time to swap out the solution for a fresh batch of silver nitrate, and resetting your silver cell. if the last run was perhaps contaminated, you can just run it through again. after a while, you'll realize you're really only using up the silver nitrate by loading it with impurities from the silver, and those impurities lead to using up your silver nitrate. and it's the pure that is being left behind. so the more pure silver you feed into it, the longer it will last.

good luck, and happy refining!
