Hydrogene Peroxyde

[Karaboga]

I have a question. What's the difference between hydrogene peroxyde 3% and 6%. Apart from the pourcentage. Is there a difference in the process or does it take longer to remove the gold? thanks for the reply.

With higher concentrations H2O2, Hydrogen Peroxide, the gold will dissolve faster.

thanks

Is your goal dissolving gold or removing gold from copper traces?

Because if it is for making AP, you do not need H2O2.
Experienced refiners can work with it to speed things up, but i do not recommend it to beginners.

How is your studies going?

How is your studies going?

compared to the beginning it's better but I still have things to learn about the components and how to processes like chips or capacitors.

I have another question. After the hydrochloric bath i use hydrochloric and bleach to dissolve the gold. And my ratio is 4/1 (200ml Hydrochloric and 50ml Bleach). Is it good?

Have you already read Hokes book?

We never use ratios, and that is even more important with HCl/Bleach.
What do you do with the HCl bath?
Remove Tin?

the HCl bath is to remove the gold, the metal under. After filtration ill add 200ml HCl and bleach until saturation for dissolving the gold and i wait 1 day for the next step

 

[Karaboga]

it's more or less 50ml

HCl, will not touch Copper alone and as such will not release the Gold foils.
You need AP for that, HCl and air bubbling will fix this.
There is no need to filter it, shake/clean off the foils with water and siphon off the fluids.
Add HCl to cover it and then a bit more, add a few drops of Bleach(Hypochlorite) until it no longer reacts then add more.
If you premix you will loose most of the Cl- and risk neutralizing the HCl.

You have not studied enough to understand why you are doing what you do.

Put your things away in a safe place and continue your studies before you try again.

He is using HCl + H2O2 for his AP and HCl + bleech for the filtered foils.
He was asking about the strength of the peroxide, which he does not need when using an air bubbler.
His terminology is a bit off, but the basics are there i think.
More studying needed though. I agree.

no i don't premix. I put the materials into the beacher, pours HCl after that i pour bleach little by little until there is no reaction. And i use also peroxyde with HCl in the first step so don't worry

A very interesting document about the cupric chloride leach.
And my visualization of how CuCl works.

You need to get your names and chemical correct so we know what you are talking about.
Your posts indicate you are mixing them and letting it stand for a day.
This is wasteful and may result in neutralized "dead" acid, now you tell us you do not do this, which is good.
Read the PDFs given to you by Martijn, they are quite useful.
