It's almost the same procedure . Dissolve alloy in nitric acid , precipitate lead in chloride form filter, treat with sodium hydroxide to get lead hydroxide, smelt with charcoal and borax. From the solution get the zinc out by alkalizing solution get the zinc hydroxide and melt with carbon and flux too
Is the decanted solution a pure enough form of stannous chloride to use for testing for Gold in solution? I need stannous chloride and have no use for the lead
Oh boy, I am pharmacist, so I know something about chemistry, but I never worked with metals in such way. Just very basic recovery and exploring cupelation (I bought micro furnace, cupels, extra pure lead, bismuth...). Also I bought basic things for silver electropurification (AgNO3, DC power suply...). I have to learn a lot...
Or you can just electrolyze the shit out of a chunkier bar of solder in some sulfuric acid. Tin leaches out when you crank up the current and plates out. Pb stays behind as PbO2. It even stayed together for me and i basically have a rod of PbO2. Well, some tin will stay behind in there and there's a metal core, but yeah, that's the lazy way lol. I got some 20g of tin like that over a few days. It looked like your spongy tin at 8:23, with spikes on the bottom. I burnt most of it trying to melt it in air, like you at 12:00, it's just too powdery. A crucible with a lid and flux help to keep the air out while melting.
@@PickyPlans The one caveat is that i don't really know the exact alloy i did this with. I just assume it's regular 60/40 ish. I used a few solder rods as thick as a pinky finger. After I ran it a while i was able to break off the tip and it was brittle. The part of the rod above the solution was still metal, so i assume there is a transition in there somewhere. I dont want to break it any more really lol. But yeah thin stuff should go faster, just has to be enough to hold itself together. It tended to expand as it turned to oxide. I did this like 10 years ago so it's kinda fuzzy, but i still have a pellet of tin and the rods lol.
@Picky Plans I think I know a way to do a better separation and purification of both lead and tin from solder. After dissolving the solder in the mixture of hydrochloric acid with either nitric acid or hydrogen peroxide, you can prepare a solution of sodium polysulfide by heating sulfur with a concentrated solution of sodium hydroxide (the solution will go from yellow to orange or even dark red depending on the reaction time and the polysulfides present). After the tin and lead solution has cooled down to room temperature dilute it with water or neutralize some of the excess acid with sodium hydroxide until it is just mildly acidic, and then add enough sodium polysulfide solution until the solution is yellow, orange or red indicating that there´s polysulfide in excess. In this step we´re precipitating the lead as black lead(II) sulfide while the tin is converted into soluble sodium thiostannate(IV) which allows us to separate them by filtration. After filtering and washing with water, wash the lead(II) sulfide with ethanol the help it dry faster. As for the filtrate, just treat it with dilute hydrochloric acid to precipitate the tin as yellow tin(IV) sulfide (it will also precipitate some sulfur which will be mixed with it, but probably can be separated by dissolving the sulfur in some xylenes), but be careful as the reaction will also release hydrogen sulfide which is pretty poisonous and stinks like rotten eggs. The lead(II) sulfide can be converted into lead(IV) oxide a.k.a. lead dioxide by oxidizing into white lead(II) sulfate with hydrogen peroxide and then dissolving it with sodium hydroxide to form soluble a soluble complex which can be turned into insoluble lead dioxide by adding sodium hypochlorite and probably heating to help the reaction.
Thanks for the explanation and the tips. Seems great but the part , diluting HCl containing Tin and lead chloride causes most of the lead chloride to percipitate out as needle crystals. I like the recipe and it is a good practice for the metallurgy of precious metals extraction. What i do
First dissolve alloy in nitric acid Collect white paste dry it (preferably) on it's own and no heat. Then try to dissolve it in hot concentrated HCl. Add enough to dissolve all So you have SnCl2
@_MuhammadRasyid_KIM_ lead isn't easy to dissolve in HCl but if you want to do this to solder alloy You can only dissolve it in conc. HCl the dilute and cool it down to get lead chloride. To turn Sn2+ in solution into Sn+4 you can bubble Cl2 gas into the solution.
@@PickyPlans Cl2 is dangerous. My lecturer doesn't give a permit to use these gases in the laboratory. would u like to give me another recommendation about oxidizing the Sn2+ to Sn4+ in this experiment that we can get the high purity Sn and low impurity? 🙏🤔 How about form SnO2 from SnCl2.2H2O? how to make SnCl2.2H2O from SnCl2? Thanks a lot, Mr🙏
@Picky Plans The reaction between tin and nitric acid doesn´t produce any tin nitrate but instead it forms tin dioxide a.k.a. tin(IV) oxide. The correct reaction is: Sn + 4 HNO3 = SnO2 + 4 NO2 + 2 H2O
Both reactions are correct... This reaction you referred to, is the reaction of tin metal with concentrated nitric acid, Which creates metastannic acid, The reaction with very diluted nitric acid makes tin nitrate....
@@PickyPlans Yes, it does happen to some extent. However, tin nitrates are very sensitive and unstable and decompose to tin dioxide quite spontaneously.
Coordination to chloride ion will lead the equation to Produce SnCl4 and going through the reduction in presence of excess Sn metal, SnCl2 Forms .In this case the product stabilizes.
I have to tell you sorry it won't be lead bicarbonate as with the exception of the alkali metals and ammonium bicarbonate all other bicarbonates of metals are unstable and decompose to normal carbonates. Lead just precipitates as normal carbonate otherwise very interesting method😊
@@PickyPlans that so great👌🏻 I hope you point at all processes exist and choose best and cheap and ideal way (Chlorine gas,AR,AP,...) for remove base metals and dissolve PGM and precipitation PGM. Best regards my friend 👍🌹
@@PickyPlans there is so weak and less info about Ruthenium and iridium ... I read just in the book and never do it but you have good and best lab and good ability for this plan work with ore contains (Au-Ag-Six sister platinums-base Metals)😉

I have to say this is perhaps the most interesting recovery channel, it is genuine not copying others and practical. I wish you remain on that line.
Now, if this guy could show us how to separate Lead from Zinc, he would have a very popular video!

That would be exactly I route I would take. Minimal effort and acceptable purity.

What i do
I understood some of the words he said
Can to tell me how to purify tin metal??
U can do it by electrolysis of impure tin
@arshadnoman9584 of course!
Can you tell me how to make Sn+4 from Sn-Pb alloy?
Is it possible to form SnCl4 or SnO2?
First dissolve alloy in nitric acid
Collect white paste dry it (preferably) on it's own and no heat.
Then try to dissolve it in hot concentrated HCl. Add enough to dissolve all
So you have SnCl2

Lead compounds are not soluble except nitrate. You should melt down the wire and pore it on something cold this will seperate tin from lead ~
