Sodium hydroxide is dangerous especially when it is hot. Avoid repeating this process at home unless you have sufficient information about what you're doing.

Hi man, realy nice silver... I have heard about using sodium carbonate instead of sodium hydroxide. Any idea about that?

@PickyPlans 10 ай бұрын

Thanks mate... Both could be used, In this case I don't like sodium carbonate because it foams too much and causes some silver shots to stick to the crucible wall.

Merhaba Salih bu çalışmalar da başarılı oldunmu hiç bazen kralları yapıp çökelti olmuyor kum ve taşlarla çalışıyorum siz maden lemi elektronik lemi çalışma yapıyorsun

İyi çalışma lar temenni ediyorum karbonat yerine hidroksit kullanmanız güzel fikir di altın rafine de gold eritirkende iyi oluyor mu hidroksit ve boraks,🔔🔔👈

Yes you can use sodium hydroxide instead of carbonate

What is the sulphuric acid ratio used to clean silver shots and did you boil it? Just want to make sure if I can use dilute sulphuric acid to wash silver powder or shots with boiling without dissolving silver into it.

@PickyPlans 10 ай бұрын

I'm not sure about boiling the powder but i did it for shots at a concentration of about 5 percent sulfuric acid... Yes it boiled for like 10 minutes.

I'm pretty sure you wont dissolve silver in dilute sulphuric acid.

Regards to you from America ❤️ I work in a small refining station. Sometimes I have silver chlorate left over. I want to try your method. On average, how many grams of dry caustic should we add to the moist silver chlorate powder? I would be very grateful if you answer, thank you and what should we pay attention to during this reaction.

Greetings, Double the weight of silver chloride is good to go but be careful hydroxide will react with crucible add a pinch of silica sand to every 10 grams of caustic to protect the melt dish

@@PickyPlans в шлаке после плавки хлорида еще серебро осталось в этом способе большие потери

@PickyPlans 4 ай бұрын

при использовании избытка гидроксида натрия весь хлорид серебра превратится в оксид серебра и хлорид натрия. а при нагревании большего количества оксида серебра при 320 ° C он превращается в металлическое серебро и кислород, так что в шлаке остается только хлорид натрия. Основная проблема этого метода заключается в том, что избыток гидроксида натрия разъедает тигель.

الافضل هو تحويل كلوريد الفضة إلا اكاسيد تم يتم الصهر. هاكدا قد تفقد القليل من الفضة.

@PickyPlans 10 ай бұрын

لم أفقد أي فضية في هذه العملية. يصنع أكسيد الفضة عندما يبدأ في الذوبان تحت هيدروكسيد الصوديوم

Sorry but its not Ultra Pure Silver. You need to do electrolysis for 999 fine silver.

@PickyPlans 10 ай бұрын

You are right according to the XRF analysis i did the next day it was 995 pure. Not Ultra literally ...

@OwlTech333 10 ай бұрын

I dare to disagree (you don’t have to run it through a cell to achieve 99.99 purity)

@HauCl4 10 ай бұрын

@@OwlTech333 yes I said "need" not "have to" you can achieve 4N with other methods like the fire assay and chemically refine it over and over again. but with this type of equipment it will be very hard to achieve that purity. so its way easier to do it with silver cell.

@PickyPlans 10 ай бұрын

I used to achieve 999+ silver with simpler equipment than these. This time, I let the chloride (from cupellation - parting) sit in the solution for an extended period. As a result, some lead chloride settled along with silver chloride and was reduced to lead metal during smelting, by filter paper as the source of carbon. (The first bar had higher purity.)
