They just sit there and look at you. I'm not an evolutionary biologist but this could actually be a good thing. None of the other surviving animals are eating them. I think the squirrels problem is poor genetics and bad sunlight🤢 That is what probably caused the mutations and deaths.

@philipbender9565 жыл бұрын
You are correct some of the pieces that I have recycled are probably worth more sold as is. I have noticed that unless you're antique sterling silver is perfect (dent and scratch free) you won't get much more than the scrap value. You will also have to wait for someone to come around that is looking for the piece you are selling. I purchase all of my sterling silver as scrap at a discounted price. So I generally end up dissolving everything that my wife doesn't want.

How long does it take for all the silver to crash out after adding the copper?
@philipbender9562 жыл бұрын
It starts to crash out immediately. Depending on how much silver is dissolved in the solution. It could take between 4 and 12 hours. There are other factors in play. If the copper gets completely coated with silver crystal it will stop crashing out. So you need to periodically refresh your copper. Once you no longer see crystal's forming on the copper. The silver is out of solution.

Hello impressive video lots of knowledge. I am First timer and made a mess of mine, used 65% nitric acid, over shot the solution without knowing and added Cooper pipe into it, pipe has disolved partially. Now question is there a way of separating silver from copper which desolved in solution? Thanks in advance
@philipbender9565 жыл бұрын
Just keep adding copper. Eventually you will consume all of your nitric acid. It takes four times as much nitric acid to dissolve copper as it does silver. Once all the nitric acid has been consumed the copper will start displacing the silver. Once all the silver has fallen out of solution you should be able to rinse the copper away with tap water. Any remaining copper or pmg's will be removed upon further purification in a silver electrolytic cell.

How pure is the silver after this step ?

%98 to %99 The last electrolysis step will remove any platinum type metals that are contaminating the silver.

Hi Philip, Please tell me the uses of the remaining Copper Nitrate solution..?
@philipbender9563 жыл бұрын
Unfortunately copper nitrate isn't very useful in the home. It's mostly used in commercial applications as a dye or antifungal agent. I generally add sodium hydroxide to my copper nitrate Solutions to form copper hydroxide. I then filter off the copper hydroxide then I melt it into copper.
