gold on ceramic ?

[ejay111]

how would i get the gold or plate off easy and can i use a sulfurlicacid cell 2 deplate it

The easiest method is to use chlorox and hcl as the plating is usually very thin, trying to run them in a sulphuric cell would require electric contact of the gold leaf during the whole process so is virtually impossible.

Hi Nickvc

So, I have had great results using AP to dissolve the gold from CPU'S , but the gold from the CPU'S is so fine cant see it.
I have also read a few posts regarding the CL process and using the CL solution with the ele Cell process...SS rod and steel wool...Do you think I can use the diluted AP solution in the same manner as the CL solution to recover the gold?

unitedgl, you are talking about two different things. recovery of PM's means separating PM's from base metal. once the base metal has been separated from the PM's, then its a matter of refining. AP is a recovery process, its used to separate gold from the copper substrate. hcl/Cl (muriatic acid and chlorine bleach) is used as a refining process. if you confuse the two or substitute one for the other, you will have nothing but trouble if it even works at all.

CPU's should not be processed in AP. there is other, better ways to process this type of material.

Thanks Geo

The following (quote)is where i was coming from, it looks like this person Recovered PM"s with CL and used that solution within the cell to refine the gold onto steel wool then used HCL to dissolve the steel wool and then melt it.

This is Very Simple and is the basis of all Chemical Gold recovery in the Au gold mines in the early days.

Take the gold coated item , (we do this with gold tailings in exploration) Boil it in a solution of Concentrated household bleach,50% water to bleach 50% for 45 Min.

Drain off the solution

Put in plastic pail

Put in stainless Steel rod (one side)

Put in roll of wire wool (other side)

get a powerful battery charger

Attach (plus) to wool and minus to SS rod.

Turn on Battery Charger .

leave 40 mins, Gold will be converted from solution to the wire wool.

Take wire wool and dissolve in crucible in hydrochloric acid, carefully drain off the acid and keep sludge at bottom.

Place crucible over Bunson burner and melt.

Small gold nugget will form in the bottom.

that is simply replacing one type of base metal for another. there is a more direct process to achieve the same thing. is one any better than another? depends on who you are talking to. when you dissolve gold into solution, cementing it out or plating it out of solution will always contaminate the gold with whatever you cement it on. so cementing values is not considered refining, it is considered recovery. refining is selectively precipitating a value from solution while leaving impurities behind. when you cement values, anything in the solution lower on the scale than the material used to cement on the reactivity scale will cement out, so using steel wool will cement everything above steel on the list. this is a good thing if you want to clean up a dirty solution such as your stock pot.
