In fact some of us prefer to not use peroxide. With an air bubbler peroxide is just another chemical we can get by with out. Keep it simple when possible.

True. It sets itself off quite nicely if you simply leave it.

The only need for peroxide is a capful to kick start the process, after that no more is required. And even then, only the household 3% stuff works to get it moving.

Jeśli przyjmiesz dokładnie tę samą mieszankę, co osoba na filmie.
Wystarczy, że policzysz 0,6 grama na kilogram i ustalisz stawkę rynkową zgodnie z tą wartością.
Nadal jestem ciekaw, skąd wziąłeś liczbę 0,13%, skoro w rzeczywistości było to około 0,6%, mniej więcej?
Jednak w prawdziwym życiu możesz otrzymać cokolwiek.
Czy to jest Ebay?

Pomylił kilogramy z funtami i wyszło mu 0,13%.

Welcome to us.
But in English please

So I am finally at the next step dissolving the gold into Aqua Regia.
It seems that my gold is dissolving but the filter paper isn't.
Do I need to increase the ratios or am I using the wrong coffee filter?

Coffe filter is not good for refining.
It should decompose but your AR need to be hot.

Its for the lack of better equipment right now.

The beaker is at 60 degrees. Do you think the solution needs to be hotter?
Also after an hour the filter starts to decompose

How did you prepare the AR?
Almost boiling at least 70-80C and then time.
Magnetic stirring helps too.

Because it’s my first time working with nitric acid I thought I take it slow.
I dropped the filter paper containing the gold foils into a beaker.
Then I added 50ml of 30% HCl and 6ml of 53% HNO3.
I waited a bit and the color started to change. After about an hour I added 6ml of nitric.
Then I put everything on a low heat to speed up the reaction.
In total I added 18ml of nitric and it’s been on heat now for about 2 hours.
The paper is dissolving but very slow but since I am not used to work with these solutions I want to take some extra precautions to get familiar with the process

Good plan and I think there is plenty Nitric.
But you should have at least 70C maybe more.
But don't let it boil.
Vigorous stirring like from a magnetic stirrer will help.
