Help with reverse electro plating

[qst42know]

All i have is 98% concentrate sulfuric acid, Should i boil it?

Your sulfuric at 98% is as concentrated as it is going to get unless it has been exposed to moisture from the air.

For concentrating it only needs heated, boiling is the wrong idea. Boiling concentrated sulfuric emits a deadly white smoke and it's not necessary to heat to such a high degree to drive out the water.

Can you teach me what should i need to do with 98% Diluted sulfuric acid before i can use it for my Reverse Electroplating Cell?
And also can i use a 6V 10A battery charger for this?
Thanks alot as you are always begin so helpful..

Best Regs....

Concentrated sulfuric acid is one of the most dangerous substances used in refining. Do not attempt to proceed if you do not have proper lab equipment and safety gear and procedures. Just google pictures of accidents with hot sulfuric to see what it can do with skin or lungs. One drop of hot sulfuric and your eye is gone, one breath of white vapour and your lungs are burned.

Invest to proper lab glass and vessels, start slow and small, be safe.

Yes, I am trying to start small. I have brought a 1L Pyrex breaker, goggle, glove, mask and a 6V adjustable AMP from 2amp to 20amp. First, After i saw Steves viedo i thought i could just simply start with 98% sulfuric acid that i brought from battery store and pour in in the breaker then black wire on lead anode and red wire on copper mesh But end up copper is dissolving and stick to the lead and also gold is not in black powder form, it strip out from the pin in tiny gold flake form and refuse to sink(End up a mess).

I am hoping to get someone who is keen to teach me step by step here and what should i do with my 98% diluted sulfuric for it to be able to use in my Sulfuric gold cell.
Thanks

If the sulfuric is attacking copper it's not concentrated enough. Concentrating battery acid is covered in the forum handbook.

Thanks Qst42know,

I have read it and will try it tomorrow(Page12). So one more question regarding the voltage and Amp for my battery charger please, May i know is 6V 10amp ok for a 1L breaker and normally how long does it takes to strip those pin(10Grams gold pin per batch)?

Thanks again.....

Many here have used a 6 volt 10 amp battery charger with success.

Making a basket that fits a 1 liter beaker is going to be a bit of a challenge. You want to try to keep 3 inches between the anode and cathode. And the edge of the basket should be as low as possible on the front edge to give a straight line between the pins and the lead strip.

You may not be able to fit 10 grams of pins in a basket that suits these requirements.

Most pins in a well designed basket should strip in seconds.

Franciz,

Have you studied the many posts on the forum discussing this cell?
Have you visited Lazersteve's web site? (See his posts for link).
Have you read the General reaction list? (And have you seen catfish's document on concentrating 32% battery acid?
Have you read the dealing with waste?
Have you read the safety section?

Can you answer these questions with a yes, and then you should have no trouble running your cell.
If your answer is no, spending some time studying these will help you (answering your questions and give you a working knowledge of the process), and (save everyone time answering your questions, many of which you have no clue to ask about), it may also give you some more questions, of steps you have not got to yet).
Without studying first you can expect to make every mistake that is possible, then spend your time asking help to get out of all of these messes, believe me that is not a quick way to learn, reading and studying you will spend far less time learning and be up and running, instead of constantly working to clean up a mess.
You will also discover many other hidden secrets of recovery and refining when you look for your answer to this question by studying, you would miss that information by asking a member a question and getting one answer.

I wish to remind anyone using this cell or concentrated sulfuric acids that if they have to dilute the acid, always pour the acid into the water.

NEVER POUR WATER INTO CONCENTRATED SULFURIC ACID.

The water would steam violently and could splash this acid all over you, at minimum eating holes in your clothing, or worse blinding, or burning you horribly.
If you are new to this make a note in your mind and on your wall.

A whole world of knowledge is just setting there waiting for you to discover it, and use it to recover gold and valuable metals. you will just miss if you do not read it.

I will try it again in this few day after concentrating sulfuric acid and i will update here for result if i do have any problem again please allow me to question again

Thank you Qst42Know,
I really appreciate your help. It seems i got the most direct answer from you.
May you success in everything you wish.

Dear all,

May i know how deep is the gold cell used in Steves website. It look great and i am looking to buy 1 on Ebay but it seems most of it got only 2inches deep.
Thanks....

The sulfuric cell in my video is about 3.5" deep. I sell them on my website (store link below) for $10 plus shipping and they come with a plastic lid. The manufacturer of the dish I use in the video changed to a wider design and slightly shallower (about 3" deep). On the shorter dish mount your anode outside the cell so it does not get in the electrolyte.

Thanks Steve,

I will try concentrating the sulfuric tomorrow and try a few pin on a breaker to make sure i know how to do it.
If it does works then your dish will be the best for me for few hundreds grams per batch.
I am just afraid if i don't know how to do it then the dish is useless to me.
I am not going to give up for sure for learning new method of recovering GOLD!!!
By the way, you have made a great video and those equipment for sales are all in great price.
Thanks for sharing...

HELLO ALL,

I have already concentrated the sulfuric from battery acid, I boil it until left 1/3 of the volume. I have also try using lead and also a copper wire to hold a pin using 12v 15A current. Guess what??? I succeed to stripped the gold pin without the acid attacking the copper !!!LOL...SUCCEED!!! Thank you everyone for helping all the time... This is the best forum i ever met, All professional is here helping one and other.
I am contacting Steve to combine shipping for his Dish and his copper mesh for my little gold mine machine... :lol:
After if i got the dish and copper mesh from Steve and if succeed please allow me to Post a step by step guide with Picture for anyone who know nothing about chemical or found it difficult to understand but willing to try until it succeed no matter what like me.

Personally i wish to thanks Qstknow and Steve for trying their best to make me understand more with their experiences, THANK YOU!!!
I may still have a long long way to go to master it but this is already a good start for me. Please allow me to ask question if i had problem for gold recovery in future...

Thanks Everyone Here,

WARMEST REGARDS,
Francis

Dear All,
Help needed again, I have stripped about 1.5Kg of gold pin in 2litre of sulfuric cell.
Now i have problem recovering the black powder, I pour the black liquid slowly to new container with 4litre of water. The problem is those black powder refuse to sink.

Should i add more water?

Franciz

 

[qst42know]

You can clean what did settle quickly and set the remaining dark solution aside. If it doesn't settle in a few days it should when you re-concentrate. You can use this over and over, you will get it eventually.

You can test a small amount of the dark solution with HCL for silver.

 

[Geo]

let everything sit for a day or more, until the liquid at the top is close to clear (you can see light through it). then syphon down to the powder. the liquid syphoned off needs to be in a container with a lid, tightly capped. the powder will have some acid in it. place this in a container that will hold the acid+powder and 3 more equal amounts of water. add the acid+powder SLOWLY to the water checking to see how hot it is getting (too much heat can cause glass to break). when all the acid+powder has been added stir and let powders settle (this may take another day) completely. when settled, decant this liquid to another container to reclaim your acid later. add water back to the powder to the level before and let settle. let this settle and decant to another container, neutralize this liquid and discard. repeat the last step until water remains clear. decant the last time and process powder.

Dear Qstknow and Geo,

Thanks for your advice. I will wait and see if it settle down to the bottom tomorrow since it is only 3Hr since i dilute the cell.

Thank you...

I friend, i have one question on the process:

After having stripped the gold with the cell, can i recovery gold from sludge, filtering the soltuion and whashing the powder?

Thanks
