Ahoj prosim ta kolko percent musí mať tá kyselina aby oddelila zlato? a čo si potom nato nalial ked si to dal von z kyseliny?

@BohumilGraman 5 күн бұрын

V podstatě je to jedno, jen když je slabší, trvá to déle. A co jsem to nalil? :-) Nevím, dej čas, ale pokaždé to tam píšu :-)

You did not mention the methods, and this is a negative point. Did you use nitric acid first or aqua regia?

Can't stress this enough, wear an N95 or even a respirator while breaking these plastic connectors apart. The amount of dust and environmental contaminates these computer fans ingest and deposit on these things cannot be at all good to breathe in. Thanks for the video

Hello! I noticed that your solution has tin slag after dissolving pins that were not previously cleaned for tin with nitric acid. I usually have problems with this if I do not remove the tin, which makes it difficult to filter the solution. Do you have any ideas on how to avoid this?

Once the reactions are complete, dilute the solution with water in a 1: 1 ratio. !VERY CAREFULLY! add the acid to the water. The reaction is STRONGLY EXOTHERMIC.

Sodium pyrosulfite (Na2S2O5) stimulates the development of allergic reactions and causes diseases of the gastrointestinal tract. Releases toxic gas on contact with acids. If in contact with eyes, may cause eye damage. But this does not prevent this chemical compound from not only releasing gold from solution, but also being a food additive E223. Пиросульфит натрия (Na2S2O5) стимулирует развитие аллергических реакций, вызывает заболевания желудочно-кишечного тракта. При контакте с кислотами выделяет токсичный газ. При попадании в глаза может вызвать повреждение глаз. Но это не мешает этому химическому соединению не только выделить золото из раствора, но и быть пищевой добавкой Е223.

Ja jsem videl video kdysi davno kde pouzival varici kyselinu dusicnou aby docilil prave toto. Mimo jiny, KDE jste sehnal dusicnou? Ja mam folie z asi 1000 klavesnic (bedna asi 60 x 40 x 40) a ja asi to cely spalim, pak odstranim ten popel s tetrachlorem, pak to vyredukuju elektrolyticky. Jeste se ale musim poradit s jednim profesorem chemie ohledne nejlepsiho postupu.

One thing bro you had to denox?? How much nitric did you use?? If you start with few mills at a time on heat and with lid on reaction stops put few more mills in until it’s resolved and the more legs you remove before you start you will use less nitric because copper takes a lot of nitric and the more copper you need more liquid to dissolve the salts in but good job we’re is the water for SMB you drop gold you need double solution water???????

sulfic acid should be like 96% atleast 86 will not work actually(only little bit). It's long time taking, dangerous, also usage of acid is high. Only one bonus that gold not lost in the process like you can do when burning.
