Refine a small amount of computer parts

[golddie]

I would like to try to refine a small amount of computer parts that have gold as an experiment.
I have 2 questions.
1) If I use javex will that be acceptable
2) Can I use sulfur dioxide gas or other metals like copper to cement the gold instead of SMB

HCl-Cl= Clorox Method = 4 Parts Muriatic, 1 Part Clorox (added in small increments).
Used to dissolve gold foils and powder. Drop gold with SMB, NO urea needed.

Thanks

What the heck is javex? I would not use copper if you have one of the other items available it will produce dirty gold.

Golddie your reference to clorox as javex must mean you are north of the border .
look just go to any wine and grape supply place and ask for some by name sodium metabisulfite if you refer to it as SMB no one will know what you are looking for.
if you are in the GTA pm me and i will give you directions.

Hi shyknee & Barren
Thanks for your help
Than javex would be the same as Clorox.
I will ask around for SMB and if I need more help I can ask you
Take care

If you have a Home Depot up there they possibly have it. Or you might be able to order it online from them.

Javex is bleach, it's just become the house hold name for bleach
Just like saying kleenex for any nose tissue or Xerox for any copy

fixed error oops

no fixed my error, hcl and javex are two diiferent things
but javex, bleach and clorox are the same thing

1. Rinse the entire contents of the filter into a straight walled beaker and cover the black sediment with HCl to twice it's thickness in depth.

2. Heat to 60C.

3. Add 10 mL of Clorox and stir until the solution no longer fizzes with tiny bubbles.

4. Repeat Clorox additions with vigorous stirring after each until color of sediment changes from black to a tan/light brown/gray or completely dissolves, whichever comes first.

5. Test solution with stannous chloride for gold.

6. Do a coarse filtration on the the liquid to remove the bulk of the sediment.

7. Thoroughly rinse the sediment in the filter.

8. Perform a final fine filtration through a vacuum filter paper and a frit or with a charmin plug.

9. Heat the filtered solution on low heat to drive off any excess chlorine.

10. Add SMB to precipitate the gold.

leach base metals first.
