Hello. I am frome Norway, and this is the first time in here. I qess you work whit chemicals in a daily basis? I am going to join in on this Canal. I am impress of you😊. Take care, and god bless you my friend. Locking forward to follow this canal😊
Thank you! No I'm not work with chemicals every day. Gold and silver recovery/refining is one of my hobbies. I'm glad you enjoyed my work! Take care, and God bless from Hungary!
The "sparkly stuff "at 11:16 is most likely Lead Iodide . it's the reaction between lead nitrate and Potassium iodide . how you got Potassium iodide in the mix is beyond me. maybe in the rinse water or a contamination from iodised salt dust you may have in your kitchen . well that's the only explanation i can think of
Interesting! We don't use iodized salt, just natural salts like himalaya and parajdi salt (parajdi is mined in romania) and I rearly used salt in silver recovery, maybe these salts contain some iodide naturally. The "SMB" I use is not SMB it's Potassium metabisulfit, the potassium defenetly in the "picture". Thank you for the toughts! 👍
@@ogbullion yes there is some iodide in natural salts a very small amount . maybe you could test your Potassium metabisulfite and natural salt with a lead nitrate solution . make up a little lead nitrate ( caution very toxic ) and drop a bit of each in and see if you get the golden rain or a yellow precipitate. if your getting your Potassium metabisulfite from the internet i wouldn't be surprised if has been bulked out with an iodide salt
I do a test on that just for curiousity. The potassium metabisulfit is food grade used for wines and not from a sketchy internet vendor if that metters.
@@ogbullion i'm mostly speculating based on watching a crap ton of chemistry content on youtube . i recall the golden rain experiment used lead nitrate and you would of had some lead in the filters , seeing as you precipitate it out as lead sulphate then filter it out i'm just putting 2 and 2 together that the sparkly crap "looks "the same as lead iodide . i still could be wrong . but if you wanted to test for iodide there would be better people out there who have made videos on the topic
At which part of precious metals refining you collect those filter papers? aquaregia filtering after dissolve all metals or nitric acid solution filtering after dissolve most of metals except gold?
What I don't understand is how there is still gold and silver in the filter papers and as supposed you rinse the filter paper with water very well after finishing filtering the aquaregia or nitric solution bearing silver?
@@ayhamhafez285 i can't rinse 100% the dissolved metals from filters not metter how hard I try, always left some. The dissolved sterling silver and other old silver items always carry some gold that i catch in the filters as black/brown mud. When i filter gold solutions and have silver contamination the filters catch the silver chloride. Lot of ways can have left precious metals in the filters thats why everybody save them.
Hmmm, I think I lost a lot of gold since I didn't save my filter papers at all, usually I use cotton filter so it take a large space comparing to filter paper. Just to make sure that I understand you well, gold that you got from the scrap filter paper was contaminated with silver chloride, right?
@@ayhamhafez285 no. The filter papers incenerated and the silver chloride turned to silver oxide, silver/ or oxide both is soluble in nitric acid, the recovered gold is pritty pure 98-99% the remaining contaminations are possible platinum group metals.
hello brother I have a question that I hope you can answer Can gold evaporate? If gold is dissolved in aqua regia and then aqua regia is evaporated at a gentle heat, will the gold evaporate with the liquid or will it settle to the bottom??
