In a crusher they could short and explode.
Disassembling manually is really the best way. But, if you pioneer the way to do bulk lots on a hobby level. You will be set.

Saadat you've got guys on this forum who do this for a living already. I'm one of them. Please trust me when I say that there really are much better things to spend your time on than these batteries if you are looking to recover precious metals.
You have to factor in your own time, and for material like this it's not time well spent when you can pick up better material without really having to try.
I mean this well and please take the genuine advice in the spirit it is intended.

Sure, I know you can because it's what nobody wants and it's also hazardous waste.
Thanks Barren. I'm afraid I confused saadat with another member, and failed to notice the language barrier was because he was from Iran.
Saadat, you asked if you could crush all the batteries together instead of sorting them. As Barren has said, crush mean squeezing, or pushing, or pressing them together. If you hit a battery with a hammer, or squeeze it with pliers, you would crush it. This would be dangerous, as lithium batteries might burst into flames or explode, and at the least would expose you to hazardous fumes.
I did not say you should assemble (to put together), or disassemble (to take apart) them manually. You should sort them manually. That means you should separate them into different piles; all the lithium batteries in one pile, all the silver batteries, in another, etc. If you disassemble lithium batteries, yes, they can explode. That's why you need to sort them, and only crush the silver oxide type.
I'm not sure I understand the quantity you have available. In one post, you mentioned 2 tons per year. In a more recent one, you said you could recover 1,000 kg per year. Either way, that's potentially a lot of silver. It will take a lot of work and a lot of chemicals, and it will produce a lot of waste, but it's a lot of silver.

OK thanks Dave
So you say I must sort silver oxide from lithium cells and then crush with a hammer mill?
How about MnO2 cells ? Any safety risk? (crush Mno2 cells with silver oxide cells)
I can buy 2 ton cells if find a fast way for recovery silver. I want trip to 3 or 4 city and buy cells 8)

Please refer to the items as batteries not as cells. When you call them cells it confuses people from other areas of the world that read the forum because they are called batteries and not called cells.
I said you need to sort them. I've never processed batteries, so I can't say whether crushing them in a hammer mill is a good idea or not.saadat68 said:
I don't know. As I said, I don't process batteries. I'm afraid you'll just have to do some studying on your own.
One of the best pieces of advice Hoke gives is to start small. You don't know how to process these batteries, but you're talking about processing 2 tons per year. I suggest starting with 1 kg. Time how long it takes to sort them. Measure the chemicals you use. Figure out what it will cost to treat the waste. If it seems profitable, try 10 kg. If that works, try 100 kg. Some processes can be scaled up. Some can't. Only you can decide if it works for you.

Many impurities are in my solution like ZnO , MnO2 and some Nickel and copper and ...
Can I get silver purity above 95% with cement and then melting with borax ? or need a silver cell?
Can I sell a 95% silver to shops ?
Edit : Got my answers here

You are trying to process something that you don't even know if you have a buyer for it. You need to find a buyer and see what they will pay before you start processing this material. Since you are in another country there is no way we can inform you if there would be a buyer of your finished material and what their requirements would be,

Any new feedback ?
Your answer is right in this thread. It is roughly 1/3 of the weight.
I don't want to distill mercury and work with mercury fumes in my small workshop so I decide switch to wet method that Juan explained in first post.
I think we must review it because we talk about mercury. I think this process has two problem
This is process for removing mercury:
When we add Hcl to silver nitrate solution we get probebly a mix of HgCl2 and Hg2Cl2 with silver chloride
HgNO3 + 2 HCl → HgCl2 + H2O + NO2
HgCl2 is soluble in water so in washing step we remove some Hg with water. This water has mercury contamination :shock:
Problem 2:
The black residue after adding ammonium hydroxide and washing step is a mix of Hg and Mercuric amidochloride
This is the reaction:
Hg2Cl2 + 2NH3 → Hg + HgNH2Cl + NH4Cl
Mercuric amidochloride is slightly soluble in cold water and decompose in hot water.

I starting to think distillation is a safer and better method to remove mercury from silver now!!!

Thank you

Ammonium hydroxide has water so some HgNH2Cl will dissolve in water and goes to next step. (participating with silver chloride, converting to metal and melting!)

What is best way to wash batteries for removing potassium hydroxide?
This is my process:
Wash with hot water
Let to settle
Decant after one day
But even after 2 days I had very small particles in water. If I want to filter it takes one week for one liter of water!!!
Is there any silver in this water ? It is bright gray from decant step

MANUEL,
I would like to ask you some questions on the work you have done on a more private level. I am brand new at this and do not know how to set this up.
Basically - I am having some issues on understanding the expected amount of silver per pound for a 100 pound amount.
My current "battery buyer" and I do not agree on the amount of silver to expect.
Thank you in advance Mitch -
