Post in English or you will not get much responseO cijeni se može pregovarati. Prah nije pročišćen. Znamo da prva ekstrakcija praha sadrži i nečistoće. Čak i po izgledu praha, poznavatelji mogu prepoznati što je u njemu. Paladij se nalazi u najvećem omjeru, a slijede platina i zlato. Ima olovne, bakrene i osnovne metale jer nije iznova pročišćena. Sadrži i neke bijele ostatke tijekom nastavka tretmana dušikom i klorom, ali još nisam siguran je li to krom ili rodij. Ne otapa se u dušiku, ostaje bijeli talog. Otopina na bazi klora topi sve, ali nakon vađenja svega navedenog, u ostatku otopine daje kristale nalik smeđe-crvenoj igli, što ukazuje na rodij. Ovo je prvo izvlačenje iz rude.
I do not know, but it do not translate other languages to English in the posts.Zašto automatski prevodi svaki tekst za mene na engleski?
I'm reading, but I don't know how to enter the text in English without it being translated immediately.I'll try to get rid of it. I think that the text remained exactly as I entered it.I do not know, but it do not translate other languages to English in the posts.
So here your posts arrives in Polish.
Do you not read your posts after you have posted them?
Hmm I did not know there was ores in Poland containing PGMs.The metal powder was extracted from the ore with chlorine at high temperatures and reduced with FeSO4. FeSO4 from chlorine water removes all PGM and gold as well as a certain amount of base metals. The powder is not purified. It contains palladium in the largest proportion, followed by platinum and gold. along with precious metals, it also takes part of lead, copper and other base metals. We can agree on the price.
If you want to sell it you need to state how much it is and I guess many will need to know the origin to be interested.The metal powder was extracted from the ore with chlorine at high temperatures and reduced with FeSO4.

Anyway Copperas (FeSO4) will not drop other than Gold of the Precious Metals, some traces may follow the Gold.
This is often used to separate Gold from PGMs.
What kind of tests have been done to verify the existence of PGMs in the powders??
How is it processed and tested?I've read that in many places, but maybe because it pulls the powder out of the chlorine solution, it also pulls the other metals. I got this after processing. It's not about Poland. Croatia.
This do not seem like crystals, it seem to be something manufactured.I am not sure if these are rhodium crystals or some other metal. They are also found in that powder in smaller quantities.
Listen, this is not Twitter, we don't repost information without adding something new, comment or question.
I used the process with ammonium chloride and yes, precisely because everything is too complicated, I would be happy to sell the powder that I get from the first extraction. The book by C.M. H. I translated and downloaded from the Internet.How is it processed and tested?
I suggest you read these links if you are going to stay on the forum.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: Screen Readable Copy of Hoke's Book
2. Then read the safety section of the forum: Safety
3. And then read about "Dealing with waste" in the forum: Dealing with Waste
Suggested reading: The Library
Be aware salts of PGMs are extremely toxic.
There is more to it than Ammonium Chloride, that is just the final step in order to partially separate it.I used the process with ammonium chloride and yes, precisely because everything is too complicated, I would be happy to sell the powder that I get from the first extraction.
