Gold Recovery from 1.35Kg of Low Grade Computer Pins

[@johntrueblood8234]

Thank you for the video, still micro scrapping for pins and other plated material. Someday ill try this process. Learning a lot through these videos.

[@KKRRenewables]

It’s always great to meet another interested person in the hobby. I’m glad you find the videos helpful, if you have any questions, please let me know. Another great resource is the gold refining forum. If you just search that up on Google, you’ll find a pretty quickly. I really appreciate your view and your comment.

I really appreciate that. I’ve learned a ton about recovery and refining and learned about as much about video editing! 😀. Thanks so much for the view and the comment.

Excellent video bro

[@KKRRenewables]

Thank you so much! I appreciate you and the view and comment.

My friend I've done so many of those pins myself. I use glass coffee pots sitting outside in our Florida sunshine. I do use an air line and fish tank bubbler. I let them sit for weeks then filter it off catch the gold then start again. When I get up around 6-7 cotton plugs I refined it an put my 3/4 to maybe a gram and keep the coffee pots filled.

[@richardhulbert9480]

Lab filters are nice but pricey. On you first filtering try jumbo cotton balls. Promise even if slower you will see a clean filtrate. Stuff them tight if using a vacuum or you suck the plug through and have to start over. Yes that sucks😅😅😅

[@KKRRenewables]

I used to have a bag of those oversized, cotton balls, but I swear I can’t find them anymore.

[@KKRRenewables]

It was recommended to me also to use Charmin toilet paper plugs, but I haven’t tried that yet.

[@richardhulbert9480]

@@KKRRenewables I think that would suffice. I get the jumbo cotton balls at Walmart. I also get the blue ship towels at harbor freight. It's like paper towels times 4. Just saying. Filter papers are best. Cotton is great. Use what you have if you don't have those and hope for the best.

[@theonewhowas7709]

really like how you;'ve upgraded your mic and talking situation, and really enjoy long videos of this subject / of our hobby :) ... do you just choose to not use nitric acid? its relativly cheap.. its not really expensive.. i ordered 450ML of nitric and they sent me 1 liter.. lol.. but that being said.. i was just wondering if you just chose to not use nitric or not.. cause all this could be done alot quicker.. thanks, also.. what is ap solution.. google doesnt help when trying to define what it is.. you're the only one i've ever heard refer to using "ap solution" would be awesome if you could make a video, describing how that solution that you're using actually works as well :)

[@KKRRenewables]

Thanks so much for the views and the comment. I’m glad someone recognizes my effort in editing and equipment as improvement. 😊. I had to use my phone on this one and the wind noise was horrible but I’ve learned quite a few tips/tricks with my editing platform to improve the sound. I really enjoy my GoPro media mod also, which cuts down the wind noise and provides a multidirectional mic. I can no longer get nitric where I live so I’m super stingy with the last bottles I have. I also have a few silver recovery experiments I’m saving the nitric for as they will require a greater volume of nitric. And muriatic acid is long lasting and cheap. My view on AP Solution…. It stands for Acid Peroxide Solution/Method. You create AP by adding a minute amount of H2O2 (hydrogen peroxide) to HCl (muriatic acid). Basically, the oxygen and the Chlorine oxidize and dissolve the base metals. You don’t need H2O2 if you have an air bubbler providing the oxygen. IMO, concentrated H2O2 should never be used in backyard hobbies as it’s very strong, but a cap full of the 3% stuff from a pharmacy is good. Many people will make the point that too much H2O2 will dissolve your gold also. And it will. So use sparingly or a very weak concentration. The other option is an air bubbler. The H2O2 (hydrogen peroxide) just gets the process moving a lot faster. The solution is really Cupric Chloride. I can do a video on it, sure 👍. Thank you for the idea. Have a great day and thank you again. 😊

[@quinton3997]

If you ever run across a old oxygen breather apparatus. I took apart and using it as a vacuum pump works great

[@KKRRenewables]

You mean like an old sleep apnea machine? I appreciate your view and your comment.

[@ANDYGLEGENDSSING]

Bit platinum in it or silver looks nice thou good job

[@KKRRenewables]

Thank you. I appreciate your view and comment!

[@Stalkerrob20]

Did some searches, and I best I come up with is ferric chloride crystals. By appearance and the fact you said there was base iron in some pins

[@KKRRenewables]

I just researched ferric chloride also. Indeed it looks like a match. Thank you so much for the view and the comment. I appreciate you.

[@urbanprospector3007]

Did you check to see if any of the pins were magnetic? If you found some, could you not cupel those pins to get the gold?

[@KKRRenewables]

Yes. I believe you could cupel them also. Thank you for your view and your comment.

[@vytasl7024]

👍👍👍

[@KKRRenewables]

Thank you!

[@prospectorpete]

Youre lucky you didn't have much foaming in the bucket. When I last tried that, it foamed so much it overflowed out of the bucket and all over my concrete

[@KKRRenewables]

Right on, I would not have enjoyed cleaning that up. I don’t think there was enough metal in the bucket to saturate the solution, and foam that much. I thought when I saw the foam that meant that I was saturated, but then I saw the color of the Solution and thought that maybe it wasn’t saturated enough to have a bubble over.

[@leewhite1969]

Are these magnetic or non-magnetic pins?

[@KKRRenewables]

They are a mixture of all pins that I collected. So they are both magnetic and non-magnetic.

[@leewhite1969]

@@KKRRenewables thank you for the response. Most people I have watched from what I can tell have only done one way or the other and I have started to get a collection of them my self and this will most likely be the route I take

[@KKRRenewables]

I think the direction is a personal preference. Good luck on your journey.

[@silver_salvage_savage]

To get it clean id inquart the bead with sterling. Nitric baths until all the blue is gone. Dissolve in aqua regia and drop it with copperas. Probably got some lead or tin in there considering its e waste. Could be pgm's I think that milky stuff was silver chloride. That could be the contaminate. Nice job and yield tho.

[@KKRRenewables]

Great info and suggestion. Thank you very much for this. I appreciate your view and your time. I’ve never been able to correctly identify silver chloride. I need more practice! 😊

[@thelovepapa123]

I watched it and didn't get the knowledge. I don't know what to watch for. Many clips show the values ​​of the substances used. What type of acid is used?

[@KKRRenewables]

Thank you very much for the view and the comment. I shall endeavor to make that more apparent in my experiments. These acids are dangerous though and should only be used with the proper protective equipment, environment, and caution. I use HCl and HNO3 to start the chemical processes. I’d advise reading CM Hoke’s book that’s been updated and made available on the goldrefiningforum.com. a wealth of knowledge. Thank you again and have a great day!

[@richardhulbert9480]

The pins you can't pull or the CPU sockets I rinse and then shake in a rinse water to get what gold I can that sticks to the plastic.

[@richardhulbert9480]

Your bubble over is a nasty green foam telling you the solution is saturated. Add some fresh hcl. You will probably get a hard puck at the bottom of the pot. Fresh hcl can remove that or I typically filter the material off add some water to dissolve the puck then filter again add fresh hcl and some of the old ap then keep on trucking.

[@richardhulbert9480]

Don't worry about the crystals. That I think is brass. I try and separate magnetic pins from non magnetic. Not sure It matters but it's what I do.

[@richardhulbert9480]

Put that old ap in a bucket with some steel and you can get the copper back. Plus it makes getting your waste solution back to neutral and safe to dispose of easier.

[@KKRRenewables]

Yep, I tried to get everything I could. I appreciate your comments, thank you for watching.

[@KKRRenewables]

Yeah, I figured that was the reason for the bubble over. I appreciate the comments and the views.

[@TechTrashCash]

Can you do electrolysis on these next time? Skip the work?

[@KKRRenewables]

I’ve never done that but thank you for asking because I’ve been thinking about it. I have amassed another decent chunk of pins and I really don’t want to do acid dissolution again. I don’t know how to do electrolytic yet but I’ll give it a go! Thank you for the view and the comment!

[@rewalston]

Something that you can do to make your gold drop settle quickly is to put your solution on a low boil and the gold settles really quickly

[@KKRRenewables]

Indeed! Thank you for the view and comment!

[@richardhulbert9480]

I have a roll of lead free solder. That works good for making stannous solution. But everytime i pull off a bga chip there are lots of tin balls. Collect them and workd as good as solder.

[@KKRRenewables]

Excellent!!! Thank you for the advice. Have you found silver in the BGA solder balls. I’ve recently started collecting these solder balls as I’ve understood there to be silver in them. Like maybe the solder for them is different? I am planning on an experiment for these solder balls pulled from circa 2015 networking devices. I really appreciate your view and your comment. Have a great day.

[@richardhulbert9480]

@@KKRRenewables I started saving them for that reason. But I haven't yet tried processing them. I hope you do find some then I will know what to do with mine.

[@KKRRenewables]

Apologies. I did not know you’d replied again. My filters on KZbin comments didnt show replies to replies. I know to check now. As soon as I get enough balls to do it, I will. Hahaha. That’s funny.

[@julianshalders6047]

Our land fills are so polluted by this stuff.

[@KKRRenewables]

Exactly. It’s so critical to get as much of these metals back in the production stream through recycling. I find myself spending a load of time pulling the smallest pieces of metal (like tension springs) from plastics. It’s unfortunate not all the plastics can be recycled. Thank you so much for your viewing time and your comment.

[@magthemagnificent8437]

I wouldn't worry about getting the impurities out of the little bead. I would put it in the safe in the house. Keep doing more refining of ewaste. Once you've collect 100 beads, melt them all together and then get the impurities out.

[@KKRRenewables]

That’s a good point. I really appreciate you. Thank you for the view and the comment. 😀

[@rewalston]

after you rinsed the SMB solution off your dropped gold, you should have given it a boil in HCl that would have cleaned up your powder significantly

[@KKRRenewables]

Thanks! Will do that next time. I appreciate your view and your comment.

[@steveperez660]

You should’ve used some borax when you were doing melt

[@KKRRenewables]

You mean before the melting process or after the melt and before the freeze? I used borax before, but not after…as I recall. Likely really hard to see the before because of my goof on the FPS. Thank you very much for the view and the comment.

[@fellpower]

In this time it takes and the costs of the chemicals and the power for heating, u lost much money. Mow the green - and u get much more income ^^

[@KKRRenewables]

Facts…. But it was fun 🤩

[@TechTrashCash]

That's a lot of plucking bro? Damn.

[@KKRRenewables]

For sure that’s a lot of pin pulling!! Thank you for your view and your comment. It’s nice to have folks recognize the effort.

[@shawnsmith9512]

When you say saturated and the solution is brown, add some peroxide and see if it turns green again. I think you are getting another copper chloride and not sufficient oxygen to get to the 2 valence state.

[@KKRRenewables]

I will try that when I get a chance and put up a short video to show real time results. Thank you for the view and comment, I really appreciate it.

Redissolve run the filter then drop it again make it cleaner

[@KKRRenewables]

Yes, great suggestion! I appreciate your view and your comment.

Probably copper or silver contaminated

[@KKRRenewables]

You are likely right. Hopefully I can get it out when I go for refining. I appreciate your view and your comment.
