GOLD RECOVERY USING A SULFURIC ACID STRIPPING CELL

This is the second video ( with sound ) where I will demonstrate the easiest way to recover Gold using a Sulfuric Acid Stripping Cell.
the operation of this Cell is due to the sulfuric acid that converts to persulfuric (H2SO5, Caro's acid) when it gets close to the anode, which then will dissolve the Gold as the dissolved Gold moves away from the anode and reaches the regular sulfuric acid it will precipitate out as the Gold mud.
What I prefer with this method is that it doesn’t attack the Copper or Zinc due to a Passivation layer (a protective oxide film )that forms when the acid concentration is above 60%. This is why I think this process is the better for processing plated and Gold filled items because it won’t dissolve the base metals which makes the processing of the Gold easier, in my opinion.
Please be extremely careful with Sulfuric Acid wearing proper PPE is a must .
We will process the low grade pins in Copper II Chloride (AP ) in the next video .
Thanks for watching

Looks like a nice little nugget is about to appear!

I’m going to process some more stuff then add to it , I have some pins in bleach and HCL now

That is good morning in cat’aneese. I speak that 5hit fluently !

That’s good , man every time I start video production she has something to say . My daughter had to have her . She feral , fight with the other cats , I have just started being able to pet her when she eats

Does the final ammonia boil convert the oxides? Strip the base metals?

Cleans up and removes copper . I was told by people way smarter to use ammonia to clean the gold up
