Game cartridge fingers!!!

[watcher6880]

Somewhere I read that sulphuric acid was easily attainable through auto store such as NAPA. would that be a wise choice by forum standards?

For the sulfuric cell look for Rooto drain cleaner or any other that has a plastic bag wrapped around the bottle. Make sure it is high percentage sulfuric acid.

The acid they sell at auto stores is diluted at about 30%. That will not work for the cell as it is, so the drain cleaner is a better source.

These are the muriatic acid bottles, correct?

Rooto (drain cleaner) is sulfuric acid to use in the sulfuric cell. The stuff from Napa (for batteries) is only about 30% sulfuric and can not be used as is for the sulfuric cell. You need 98% and better sulfuric for the cell.

Muriatic acid is in the paint section for cleaning bricks and concrete, and maybe in the pool chemical section if its the right season in your area.

well I have been reading up on Lazersteve's PDFs and these have clarified a lot of issues I have been having. The AP process seems to be what I am leaning towards (hcl and hydrogen peroxide) for the fingers. But my question is, would the SMB possibly drop more out than the gold?

 

[watcher6880]

Also once it precipitates the gold into a black powder then the AR refining process would be necessary to bring it into it's natural tan powder form?

 

[watcher6880]

My biggest worry is contaminated base metals from the tin soldering getting into the mix. I have not seen this occur before but was told that tin contaminants can cause the AR solution to "gel".

After you have dissolved the base metals in HCL/H2O2, You will need to pour the solution through a filter to separate the Gold foils. Then you need to rinse the foils with HCL a couple of times until the solution is clear. Then rinse with water and decant. After that, you cover the foils with HCL and very slowly add some Clorox bleach. Be aware of the fumes. That will dissolve the Gold. Pour that solution through a filter to separate any left over particles of plastic, solder mask, or other trash. Let that set for about 24 hours, then add about three times the amount of water. This is the point where you can add some SMB to precipitate the Gold. If you followed the process correctly, the Gold should already be pretty pure and will not need further refining. I suggest you go back to Steves site and watch the AP videos, it is explained quite well there. :|

Umm, :roll: I am going to have to get back with that as per my version of the media player is supported by 64bit and the media player on Steve's site doesn't want to play with it

I have problems with the videos there too. I think it's a Microsoft thing. Maybe if the videos were in a form to play on a VLC player or similar, it would be easier for people who don't run Windows to see the videos. The Firefox plugins don't always work there. :|
Anyway, I wouldn't use AR for these fingers. I think it is just adding expense and more dangers to a simple, proven process.

Hey guys just wanted to give you an update and thank you all especially Claudie. I started my first batch using the hcl/h202 method described on steve's site on a small test batch. Liquid immediately went to a nice yellowish green color and the foils were fizzing and falling off. Magic!!! In an hour I will be checking on the solution and will take pics. I juat can't wait. I hope all of my studying pays off. Again thanks a bunch to everyone on this forum who does not have to but shares their knowledge so that others may achieve as well. Truly unselfish. I'm glad to be a part of this community.

Since my last post, All of the fingers have been removed into the solution and as per Steve's instructions, sprayed water (minimally with a small finertip spray bottle) to remove any excess gold back into the solution from the spent fingerboards. I now have two jars full of the foils in the solution. Just makes me happy to see such progess. I guess what I am wondering is after I have filtered it all out, what is the best way to remove the fold flakes that stick to the filter regardless of turning it inside out to use for an hcl wash (of course after removing most of the trash and chip pieces). After this I should be ready for my hcl-clorox dissolving the foils.

hey guys
Umm.. watcher how long did it take (rhetorical no answer needed)
I did this the first couple of times :roll: but if you want to see your gold a little quicker i suggest you buy a fish aerator ( air pump ) at walmart

The cheap one i think is $6.00 in the pet/fish department
and an extra package of hose (the clear tubing )for the pump
put the hose on the outlet of the pump and the other end in the AP
solution, the closer to the bottom the better so you see bubles coming up

Some here like to take a sewing needle, heat the tip and poke a few holes to the end of the hose in the solution

I wouldn't worry about tin yet as the fingers look to be close cut and have no solder if that is correct
good luck 8) 8)
thanks steyr223

Watcher the small flakes on your filter papers can be recovered, my suggestion is to save all your used filters, let them dry and store them in a plastic tub and when time allows simply incinerate and wash with Hcl and then dissolve with either AR or Hcl and bleach....it can be a decent amount if you save them long enough 8)

Hey watcher
I use a pump up spray bottle
Just hold the filter in the bottom of a bucket and spray from top to bottom of filter untill clean,then toss the. Filter in your filter storage container
let your gold settle and slowly pour off just the water (leave gold In bucket
As Steve shows add muriatic acid just enough to cover foils and slowly tilt bucket about 45° and roll back and forth as to make the muriatic roll past your foils
Let settle pour off into stock pot repeat 3 times last time let sit for 1/2 HR then pour off. Don't worry about water at this point it can be poured off before the hcl/Cl
Thanks steyr223. Hope this is helpfull
