SILVER contacts recovery - running large batches

de-soldering silver contact points - running large batches

[@davidtweeddale2027]

Thank you very much. I have watched your videos and am now doing exactly as you have taught with great results. The only thing that I have done differently is doing the Portland cement cuppelation twice using fresh Portland on the second go around in hopes that it absorbs the base metals easier as it affords more unused surface area.

Thank you so much for freely sharing your knowledge!

Those contacts will have to be chemically treated to separate the high quantity of cadmium thats in those contacts which is a toxic metal, it's best to leave the individual contacts loose so the nitric acid can dissolve them quicker.

Verry good Killer.Whats Cadmium

Nice silver bar! Any idea what the purity of that kind of process was?? I know it was almost 2 years ago, but I'm looking to start my silver recovery in the future and I'm looking at different techniques!!!

999 can be achieved using cupellation kzbin.info/www/bejne/g6inl4iunLOrm6M

[@wilyamvogtoraytto9519]

no judgement was good but one? .why did you melt it more then 2or ,3... thanks

[@OwlTech333]

each melt eliminates different contaminants

[@hafeezrehman3566]

Good very easy idea

Hi. Iv been getting silver out of contacts for the last few years and there is about 63% silver in each contact. Doing this way is much easier than with acid and iv tried it, i dont think you can reach a purity higher than 90%, mybe even a bit less

[@OwlTech333]

Stone Age 999+ can be reached kzbin.info/www/bejne/g6inl4iunLOrm6M

Where do you find contactors that big?

[@510Redneck]

Old Industrial gen sets.. breakers etc. have a good amount

What is solder made of? Does Solder contain Silver? Is it worth trying to recover silver solder from copper arms?

[@euro6110]

Good

Owltech how much i earn for my 300grams of silver contacts???how much per gram?

[@OwlTech333]

Depends on the silver content, as most of them are not pure silver

@@OwlTech333 How owltech....My silver is from contactors and relays and I think it is 95% silver..how much is it?

[@OwlTech333]

@@pinoypinoy467 How could I know that? The points vary from 30% to 99% Ag which ones you have and how many of each? How much do they weigh?

[@tagamontanosa9586]

what if I mix platinum and silver what would happen.

[@OwlTech333]

taga montanosa if the silver to platinum ratio is bigger than 9:1 then some of the platinum will be dissolved by nitric acid

[@tagamontanosa9586]

thank you ah really I thought that platinum would be harder than silver so I just assume that maybe silver one will be dissolved.

bukan hanya Ag di situ juga terkadang ada pd

Not in these ones

good! how many?

OwlTech owltech....i have 400g of silver contact relay...how much i earn with it?????

[@shujin7024]

@@kaylajjdahajj9636 it is said somewhere in there comments that it contains like 35% silver, lets say we downgrade this to 30% for fun, 30g of silver x4 you got 120g of pure silver, that's worth around 100$USD but you need to put some effort into getting it out into pure silver :) hope this helps even if 5 years late to this party
