So i always kept my Aluminium Bronze slag and skimmed stuff in the hope to remelt when i had a heap to extract every bit i could so here is that video where i try extract as much as i can from 2.85KGS of Slag.

Mate, that was BRILLIANT!!! Talk about recycling. 27% is damn good. I’m kicking myself for everything that I’ve wasted. Four important points: 1) Your Mrs is an angel. If I tried casting on such a nicely paved driveway as yours, I’d be sharing the dog’s bowl all week. 2) I don’t want to alarm you, but there was some strange bloke messing about in your garage - there’s a glimpse of him towards the end of your vid 3) I've heard of this VegOilGuy bloke... handsome chap I'm told... but who's this Dweeb character? 4) Can I hire you to clean my garage please
Yeah i recon i could have really gotten a touch more but on this particular ocassion i just wanted to try it this way as it was my first Al/Br remelt. i should have broke it up more with a hammer and sifted the crap out premelt but thats something ill do next time. Yeah my missis puts up with alot of stuff but shes married to a youtube sensation so she accepts it. That swdweeb guy gonna be the next big thing matey his name will be up in lights (just under our name). Strange bloke yeah but hes cleaning so ill just ignore him🤘😏
HAHAHAHAHAHA that vegoilguy is hilarious...
Should have molten some salt in your crucible before putting the scraps in. Dissolves the oxides, which allows the metal to coagulate; even tiny hidden drops, and stops new oxides from forming. Plain table salt (sodium or potassium) works but you can add some magnesium or calcium chloride too (often sold as deicing-salts) which are more aggressive in dissolving oxides. Doesnt add much cost or complexity and youll be throwing away zero metallic metals.this way.
Dam matey you sound like you know your stuff, too technical for me mate I’ll just stick to what I know I don’t mind if I have to throw out a tiny bit😁👍🏻
Well lets say sounds can be deceiving... I never actually tried this with copper base metals, only zinc and aluminium, but I think it should work much the same. Shouldnt be too technical to try dumping some table salt in your crucible tho; melting metal is an experimental science id say.. I think you might be surprised how much metal you could still get out of it.
Yeah definitely experimental for sure😁👍🏻
Yes, ordinary salt works normally. You can also throw a powder of charcoal, it will restore copper from oxides.
👍🏻
Only just discovered your channel the other week then went on a binge of all your uploads. Very entertaining and well made videos, fantastic collection, and loving the new furnace! 😉
Well thanks Aden I appreciate that . And If you have any people you think might like these vids let them know too. I’ll take all the help I can get my friend . Oh and welcome aboard🤘🏻😁🤘🏻
bigstackD Casting I'll try to, but I don't think I know many who are interested in watching people melt and cast molten metal, but I'll see what I can do! Needless to say, even I was getting frustrating with the amount of slag you had to dig out. I was starting to think, "Is there gonna be any metal to cast at all!?" 😂
I know right it was pretty disheartening but I’m so glad there was some molten metal waiting for me at the bottom😁👍🏻
bigstackD Casting I have to say though, when it comes to the lifespan of your crucibles, you really do push it to its last breath. 😂😂
Yeah matey I certainly do push my luck that’s for sure🤣
I do a lot of casting with lead alloy. Dross is mostly lead oxide. To remove the O atom I add carbon. I just use sawdust but any carbon will work. During the heat the Carbon and excess oxygen makes Co2 and goes away leaving lead and some ash. I get back over 70% back. Should work with other alloys also.
So, you just add the sawdust to the slag while it is hot enough to burn? If you are melting aluminum cans would this also work to float the dross off? redfox007me2@yahoo.com
Doesn't work with aluminum (and aluminum alloys) though, because aluminum bonds to oxygen more strongly than carbon does.
Lead has a relatively weaker bond with oxygen compared to say Aluminum because of how weak the nuclear forces are on the outer most electrons
You are the only that can transform trash in treasure!!!! And I really like your poetic sentences!
Love the quote! :) About 30% recovery is really good, too! Next time I suggest doing some preprocessing before actually melting it. A simple acid wash would do a lot to separate out the metal from the carbon and other crap that you don't want in there, and should improve your overall yield. If you want to really get into it you can start doing displacement reactions to really isolate the Cu and Au specifically.
Ohh that sounds a bit to technical for me but yeah next heap I do I’ll definitely do some clean up first even if it’s as simple as crushing it up and sifting the sand and rocks premelt🤷🏻♂️😁👍🏻
@@bigstackD no no...dnt...its sooo good to c u gting so mch dross out...
You got a lot more out of that than I thought. 👍🏻 great job! I was wondering at first too if you were gonna get any at all. Thanks for the shout out! I’ll have to join that challenge one of these days 👍🏻
Yeah I know I almost thought I was wasting my time I was so glad to find molten metal at the bottom. Hopefully we can pass the 900 sub Mark today then will go for 950 or 1000 next week but will bloody get there🤘🏻😁
bigstackD Casting yes we will 👍🏻 yeah it always hides on the the bottom. After I remelted the slag from those cans I got quite a bit more. Ended up with over 10lbs total
Mmmmm 10lbs Of Solid Aluminium 🤤🤤🤤
Thats what we call a satisfying video. From scraps to coins. Pretty impresive. Keep it up man!
Cheers matey I appreciate that😁👍🏻
Shit, that was pretty impressive man. Nice quote too. Can't wait for the metal casting challenge.🔥🔥🔥🔥
Hey bro did you see you won a gram of gold on eWaste bens channel👏🏻👏🏻. Yeah it was more than I expected from that slag. I’ll probably chuck a corny metal quote in every now and then😁👍🏻
Yeah man, totally stoked. "I actually am a winner" Not just to my mum... That quote was gold mate. Another way to cement your name in history...
Cheers matey 😁👍🏻. Your a winner to me too☺️
You got WAY more than I thought you would. Great job!!
That quote at the END WAS SICK!!
Great yield on the slag melt! A fine stack of coins for the horde! And the start of a new slag collection! :D Devil Forge does very well with all your furnace needs! Thanx D!
Thanks Jerk yes I’m very happy with the result. The furnace is so great but bloody scary to use, I put in the furnace a heap of aluminium today went to the workbench and grabbed a Pepsi came back a minute later and it had already bloody melted😳. God damn I’m loving this furnace 🤘🏻😀🤘🏻
Hey D, I go back and watch older videos you made when I have the time. Always enjoy them. Anyways, on this recovering from slag vid, I just wanted to point something out. Dude, that was a huge crucible compared to the small size coins you made. You poured like a pro. Every single coin was completely filled with no excess on the molds, round after round up until the last little bit that was left. Awesome work man. You should pat yourself on the back for that skill.
Yeah thanks for that 🤗. Some days everything just goes perfect 👌🏻 other times not so much but I don’t stress , no point stressing I don’t recon . The guys I work with wonder how I’m soo laid back at my actual work even after a big fire or explosion but if no ones hurt and we learn something from it I think that’s a good thing , plus as I tell them we don’t get paid any extra to stress out so I won’t be going that😉😁
bigstackD Casting - Big fires and explosions?! What kind of office are you working in? And how do I apply to work there?? 😋
makes me smile when I see how your channel is growing and building a good community of people posting comments - hats off to you mate to reply to us, great recovery - saving 1kg from going into landfill is always a thumbs up
Cheers Dale always appreciate your comments mate 👍🏻. Yeah channels really cruising along nicely it’s certainly starting to have all the hard work slowly start to pay off . Yeah a great recovery Although next time I will crush and sift the rocks and sand out before melting for even higher yield👍🏻
Exactly what I was looking for! Great video bloke
👍🏻😁
That’s pretty good, as I was watching you remove all the slag I was thinking you were going to end up with nothing. 👍🏼
Yeah a pleasant surprise luckily or ide have been pretty grumpy 😉😁
Great to see you recovering all you can ! Great stuff in my eyes bud ! The new furnace looks like it is working great. A bunch faster than the old beater eh. Looks like this was worth the time and gas bud, Well done fella !
Thanks mate I appreciate it. Yes definitely worth doing for sure and this furnace is unbelievably awesome. I melted some aluminium today and it felt like it melted in seconds it is scary and really powerful this furnace👍🏻😁
I am definitely going to use the wool liner if I ever get mine built. I just need to order it now.
Just make sure you use all proper protection. Alot of people say the wool is really really bad but there’s a lot of mixed reviews of it🤷🏻♂️. Safety first Dean👍🏻
Absolutely. Thanks bud !
Matey, Love you Very Much, May God bless you with more❣️
Yay! Crossover video coming soon. Looking forward to that.
😁👍🏻
These recycling videos are my favorite!
Just like 'Trash to Treasure' videos I love seeing useable metal being recovered from the slag.
You are very organized old boy, keep up to good work! Cheers from the UK!
Yeah cheers matey I appreciate it👍🏻😁
So glad I found your channel! It's been my entertain for the past week. Really really cool stuff! Do you ever sell your small cast coins? Particularly the ones with a skull on them? I'd love to buy one, though shipping from AUS would probably pretty cost prohibitive. Anyone you would recommend buying from in the US for something similar? Just looking for a neat little cast something or other in copper or that nice looking aluminum bronze that would make me feel like I have pirate treasure. Thanks and keep up the great work!
Always sparkling beautiful work😍😍😍😍😙
Thank you for your always great comments my friend 🤘🏻😁🤘🏻 😀😆☺️😊
bigstackD Casting love you man 😙😙
That's some really nice coins that could've gone into the bin if that slag were to have gotten discarded earlier on. Smart move to save that stuff. Very satisfying to watch! :)
Thanks matey yeah a bonus to say the least my friend 😁👍🏻. I’m glad you enjoyed watching it😃
Ah, slag! The Triceratops Dinobot from Generation 1 Transformers, and bizarrely, also a Transformer's cussword.
Oh yeah slag , he was voiced by Neil Ross if I remember correctly 🤔👍🏻
Also, sweet AF set-up in the garage, mah dude.
Thanks mate I don’t have a big shed so the garage is my shed , luckily I have a third three car garage or ide be shit out of luck and very crowded😁👍🏻
Really interesting. I always wondered what would happen if you remelted a bunch of slag what the recovery would be. Really cool video.
new comment for the give away, love your puppers and look forward to seeing them both each video
Thanks for sharing
Thanks for watching 😁👍🏻
Nice. Aluminum Bronze.
These are really enjoyable to watch
Well thank you my friend I’m glad you enjoy them😁👍🏻
Just some advice, you need to grind the slag to powder and suspend it in a fluid that is more dense than the slag and less dense than the copper, so the waste slag will float to the top and the copper will sink to the bottom. Then you will get nearly 100% recovery. The density of copper slag is only around 6 grams per cm cubed, while pure copper is about 9 grams per cm cubed. Aluminum is also heavier than its slag and I know that copper is around 3 times the weight of aluminum, but I can’t find the ratio. I hope this helps you in the future.
So now we now how much there was in 1.78 kilos of slag 😂 good to see how you get all of the metals out 👍🏻. I am totally up to date with your vids now. Going to look at your mates channel too!
I'll keep it simple, I love your videos.
🤘🏻😆🤘🏻
Как золотые монеты) Красивый сплав 👍
Amazing
1:10 = "How much do you gonna cast today?" "Ah, just a spoonful."
Hey bud. See the difference between kaowool and refractory cement? If you align refractory brick in there too, you'll increase the life span of the wool so much. Great quote brother. No one really understands it well except people who practice this hobby. And remelting slag is definitely worth it!
Thanks mate i appreciate your always friendly comments 😁👍🏻. Yeah I got a whole roll of this KAowool stuff for $80 so I’ve got plenty to replace it with if ever breaks down Plus I don’t want to take up chamber space as my tongs only just fit now to pick up my crucible 👍🏻. But yes having even very thin factory cement in there as well would definitely help on hundred percent.
Awesome vid!
I guess that's a great yield compared to processing raw ore! Nice shiny chunky coins :)
Yeah mate I’m now starting to wonder about all the slag I threw out over the years 🤔oh well at least I know now but next time I think I’ll crush it up a bit and sift out the small rocks and sand before melting to give an even better yield 👍🏻
@@bigstackD I wonder how the rocks and sand get in there in the first place... You start by melting scrap industrial waste, so how does that crap get in the slag? I can understand metal oxides from melting the metals but rocks?
Good video bro thanks
Holy cow that's a lot of slag!
Digging the new furnace.
Yeah she a beauty that’s for sure 😁👍🏻
Would it work better to break the slag up first? What about putting it on a steel grate so the aluminum melts through the steel and the dross doesn't fall in?
I Found This Video So Satisfying 😍
Thanks matey I’m glad 😁👍🏻
BigStackD AKA the most underrated content creator
That's a lot more than I thought you'd get from that! Every time I try to remelt slag, all I get is the same slag back... ;-)
Yeah I was pleasantly surprised matey but next time I think I’ll crush it up a bit first and try sift out or separate the sand n rocks before melting for hopefully a better yield😁👍🏻
Beauiful. The last big piece of hard slag I am sure scrap dealer will buy that as brass. The smelter Will electrolysis the copper.
Yeah they probably would take it but nah it’s not for them👍🏻
i love that forge!!!!!
Me too🤘🏻😁🤘🏻
Interesting experiment. You saved a Kilo of alum bronze from going to the trash bin. So thats a pro. At the same time you could of melted alot more new scrap and done a bigger pour. But looks like you had fun doin it!
Yeah I definitely could’ve done a bigger pour for sure but just wanted to concentrate on this one and see exactly how much I got so I can work it out for future melts. Next time I will crush up and try remove sand and rubbish from slag before I melt for hopefully a better yield 👍🏻😁
جميل ما تقوم في عمله أستمر في هذا الإبداع أتمنى لك النجاح الدائم
I wonder if it's possible to make a screen filter of sorts from tungsten to filter out slag so there isn't as much waste.
"It's like granola, it even comes in bar form."
Man it may just be me but it seems like it even pours better from that new heater awsome video again.👍👍👍👍🍺🍺🍺🍺
Yeah it certainly does pour better although like you said it would be the new furnace as that easily over heats the metal 👍🏻😁
Nice recovery, 👍🏼
Cheers Fred yeah and to think I was gonna throw it away. 😁👍🏻
How do you get all the materials that you smelt? I have a smelter set up but I don’t really use it cause I rarely get any materials... do you just ask people for all their old wiring and what not?
Never disappoint
Thanks Matey I appreciate your comment😁👍🏻
Makes me happy
🤘🏻😆🤘🏻
You should do a chemical leech out on the sand and rock slag . It may be some thing other than that . You can do it with a fish tank pump . I forgot what home chemicals to use , It step up like a fountain
Now that’s definitely the wrong channel for that 🤔plus I don’t have the vocabulary or the brainpower😁👍🏻
انت انسان...مبدع

I subbed and clicked the bell!
Awesome matey welcome aboard 😆👍🏻
awesome video :) good that you can turn something trash into actually something that is worth a little
Good luck in the challenge! Even if there is no winners and losers I wish you: "Winner winner chicken dinner" 😀
Yeah matey cheers 🤘🏻😁🤘🏻. It’s more just 3 guys producing the same item just in a few different ways . I’m 100% sure mine won’t be near as good as Geoff or Perry’s but I don’t mind there good guys so they can have the glory 👍🏻😁
Can you tell me what is the silvery coating on many brass objects, such as prongs on plugs, antennae, etc.?
I’m no expert but I know that taps and shower heads and that type of stuff it’s very thinly chrome plated over the brass , my electrician mate says electrical switches and some plugs have silver in them or are silver coated so there’s a couple ideas for ya. Even gold plated electrical things are around everywhere but gold plated anything contain very little gold , fun fact an Oz of gold can be flattened out into a 300 square foot piece of gold 😯. A bit of rambling here I know but hopefully I answered some of ya question😁👍🏻
Nice
cool melt!!
Cheers bro 😁👍🏻
Muy bueno
soon 20k subscribers. congrats
Yeah 20k will happen next month I recon 🤞🏻🤞🏻 👍🏻
Just what do you do with all your coins or Ingots? I'm thinking of doing the same thing.
Bravo my rich Bro.....
🤘🏻😆🤘🏻
What do you think about buying a ready made forge like the one you have VS building one like your old one? I'm trying to scrounge up materials for a forge but it's taking forever
Honestly mate If I had the money wen I started I would definitely have just bought one that’s ready to go to save sooo much rootn around. but there is alot of satisfaction to have made your own . Although with the time it takes to scrounge up all the pieces then cut it size it build it cement it weld it I would just get one that’s already to go 😁👍🏻
would a slotted spoon or steel mesh be good for slag scraping? im not sure i the slag is too fine for a slotted spoon, or if the liquid metal is too thick for mesh strainers, but i figure if it works, you would be able to remove more slag and lose less metal.
Yes a slotted spoon should work fine as this molten metal can be as thin as water if it’s heated correctly but steel mesh would not work👌🏻😁
Having said that it wouldn’t really work with aluminium only brass and copper and these mixed metal alloys . aluminium has a very thick surface tension so wouldn’t work well 👍🏻
I'm curious to know how long you had to run the furnace to remelt all the dross. I have a few KG's of it myself.
I love your videos
I smell a give away...LOL. Nice yield from all that slag. I do the same with my lead slag.
Yeah definitely well worth melting again for any extra yield will always be a bonus I reckon😁👍🏻
👍
Not a bad haul yes yes
Those remaining slag look very nice
😁👍🏻
Wow
😁👍🏻
😎👍
When you melt slag metal how much metal, general percentage, do you actually recover? Curiosity is getting the better of me! God bless❣
First time that I've seen so much slag...
Just asking because my scientific mind is curious but if you melted a bunch of different metals together and filled the crucible up would the density of different metals be layered if you just let the crucible cool and put it all out as one block?
Not bad , I’m with ya on not waisting an ounce .
i wonder how much worth of coins and ingots you got on your shelf at this point. do you ever cash the stuff in or do you plan on one day having everything turned into something else at one point.
Kinda scary the thought of getting into this as a hobby with OCD. The amount of gas and time I'd consume refining slag over and over trying to recover every last atom.
It's amazing what can be recovered from slag...
Indeed 👍🏻and to think people would normally throw it out 😁
I have a felling that your going to reach 1millon subs before next year
Here’s hoping Jake👊🏻😁
@@bigstackD no hope, i can feel it ;)
That pile of slag reminds me a little bit of gold maybe like it's precious in some way
This may be a silly question, but why do you add the aluminum to the other Metal?
Ok, just ONE more melting video, then I'll get on with my productive day
My good Sir, I'm catching up on all your older Vids & I'm just curious. What kind of Beer do you drink? Australian or American? -A Fan from America.
1000th like 👍😎👌
Massa
27% that's pretty dang good. I know 2 people personally that's done muffin ingots and trial sand molds. (beginners stuff) I'll be willing to bet that they threw away their slag.
Yeah i used to throw away my slag but from now on I definitely won’t. If I skimmed the metal properly there probably would’ve been a lot less than 27%, it could’ve been lazy skimming on my part but either way people have found it very interesting
Out of curiosity did you use any flux (basically light table salt. Which is a mix of sodium chloride i.e. regular salt, and potassium chloride) Perry has a video using it to get better yields from swarf.
Oh ok swarf🤔. I’ll have to look that up👍🏻. Nah I never ever use fluxes mate to the disappointment of a few people🤷🏻♂️.
Swarf: fine chips or filings of material produced by a machining operation. also known as chips, turnings, filings, or shavings, but generally called swarf when there is a large pile of debris or waste resulting from machining or other subtractive manufacturing processes. Why use flux... I suggest watching these three videos 1) without using flux: kzhead.info/sun/lbmAgZlvfYidaac/bejne.html 2) Here is a video where Paul mentions the whole oxidation thing with cans when you don't have a metal pool to dunk the cans under. kzhead.info/sun/o5SMXcevsX1oeoE/bejne.html 3) An attempt at following Paul's example and getting a better yield from swarf (but likely using too much flux): kzhead.info/sun/qtSvZ9WDZ4yQZok/bejne.html reprocessing dross is something that likely needs some flux to get a better yield.
Oh cool mate I work tonight so I’ll definitely check out those links 😉. Thanks bro appreciate it 😁👍🏻
I would love to have a beer with you while you do some metal melting.
Where do you live ?
@@bigstackD sadly International. India actually. We have blacksmiths and all but not like this cool in KZhead videos.
Oh well 🤷🏻♂️. Maybe 1 day .

Have you thought about getting different shape ingot molds like a octagon shape or something. Just to be a bit different. I don’t watch many different melt channels so I’m not sure if it’s already done by other people
I actually bought a heap of graphite blocks and I will be grinding out different shapes with my Dremel hopefully I’ll have a steady hand and can do it properly👍🏻😉
Awesome can’t wait
Great videos by the way. Straight to the point and not a bunch of unnecessary talking
