It's amazing how much Copper you can get from crushing and smelting down a small rock of Malachite ore. If anyone has a better way of doing it, please leave us a comment on how to do that. PLUS - all the Copper we smelted down today we will be giving away ....how do ya like them beans. Next, we will turn that Copper into Gold using the Philosophers stone ....stay tuned .
They say you learn something new everyday, and today I learnt all about copper. Loved it. Thank you so much Jeff. Years ago I can remember watching my dad melt down lead to make fishing weights. Always fascinated me. But, through dad's work trade, he ended up with severe lead poisoning! So, whenever he melted down lead, he had to drink a pint of full fat milk. This helped to neutralise the lead in his system. He's nearly 83 & having radiotherapy treatment (had 3rd dose today) but he does buy the fishing weights instead now!! Many thanks for all your hard work Jeff. Much appreciated. Take care.
I agree I have better pours and avoid fast cooling I also use a bigger mold it doesn’t have to be filled to the top a 5oz to 10oz molds are nice and they avoid spill over
Hi Mr. JEFF, (and Slim) Post bar making you can use tomato paste to clean copper. The acidity of 🍅 🍅 🍅 cleans the bottoms of my copper kitchen pans quite well. Worth a shot smart feller.
What a great video Jeff. Very interesting to see this and that great ripper shout out, at 58 seconds. And the extra funny stuff…. The ear guy and the “what’s that?” guy.. love watching.
If anyone knows how to cast nice metal bars it will be the Australian guy from the bigstackD Casting YT channel. He made an art out of making metal bars from all sorts of scrap metal. He also shows how he does it, and how he gives the bars a nice finishing polish. I'm sure that if you watch his videos that you can learn from it. And besides that it is a joy to watch his videos.
I like it when Jeff pretends his a novice, he explains "see the mistake" I made, so, other words, don't go be a fart smeller and do this here at home kids, thermal shocking, water vaper creating bubbles in the cast. If anything, it's being in a hurry, having stage fright to perform in front of camera lences in a timeous fashion and not the fact that he does not know. OH he knows, OH the humanity...take 6...
I asked BigstackD to do a copper ore video a couple of years ago , as far as I know he still hasn’t done it . But I am more than happy to be corrected. Well done Jeff for doing it .
I just came across this video and I'm so glad..Bro you're f*ckin hilarious....I'm talking seriously entertaining..Can't wait to watch more of your content !!
And thank you enough you are the man I like all your educational videos thank you thank you Jeff for taking the time to do that there's people out here that that really love that profession and are just learning and thank God it's through you good man
Eureka Yeee Haaa I think I will keep the course natural looking Copper nuggets Jeff.. Well done on sharing your process on converting natural copper oar to bars.. Have a wonderful weekend Jeff and Lila.. Cheers Tony Famo59 and Wendy 👍🥂⛏🤓
To get a decent looking bar from metal, you should get your mold hot enough that it glows and keep it there until you are finished pouring, this allows the metal to stay liquid for longer so that bubbles rise up and out, and the liquid is able to level off. You'll still likely get some defects from the bar shriveling up in the cold, but it'll shine up very well.
I've seen other people also sprinkle some powdered graphite in their mold when they pour in their smelted metals. Does that make a significant difference?
@@dionh70 If you are using a steel mold or similar, it helps improve the finish and release of the metal, but if you use a graphite mold it's made of the stuff.
Many years ago, I visited a copper smelter in upper Michigan. They poured the copper into molds made of copper. Immediately after the mold was filled, the whole thing was sprayed with water. Shortly after, the ingots were solid enough to be dumped out of the mold into a pool of water. The ingots were quite nice looking, being only slightly discoloured. Possibly a mold of the same material resulted in the ingots being so nice,
Smashed the flux! Lol! Why did I find that very tongue in cheek? Or is it just my way of thinking 🤔?? 😂 Hope you're both keeping well over there my lovelies & not too hot 🥵 Stay safe.
The mineral itself is more beautiful, and in my opinion more valuable than the garbage piece of copper you get, besides all the process needed and cancer from the dust. Nice and informative video anyhow.
What up Jeffery Scott here Hey, that's awesome, beautiful stuff. Thank you for sharing that smelting fun. I'll tell ya what though, it looks freakin hot! Oh that's right, it wasn't hot at all, due to the cozy weather. Lol Hilarious!!🤣🙂
Thanks Jeff, I have a few good copper vain’s on one or two of my claims. I haven’t done anything yet the copper yet. Because I wasn’t sure how to smelt it out. So thanks again & please keep the videos coming.
Nice video bud I go up to copper country quite often... Aka the keweenaw peninsula of Michigan... Going to have to try some of the techniques you use in your videos
Addrock and bigstackd use cardboard under the crucible when firing copper to stop sticking must just be that ash that stops the sticking if you need to penny pinch 👌
Very satisfying video, some people use borax to melt copper so it can clean all that unpured copper out of it!! I'm new to your channel so far I'm loving all your videos, take care and God bless
Hi, Jeff I would get your mould nice and hot pour at 1200 degrees C and pour at least 1 pound of copper or about 1/2 a kg for perfect bars and should turn out perfect 👍 Thanks for sharing. PS I poured 5 bars just yesterday about 6 pounds each😃beautiful 👍
Crushing the ore qill be a faster/better reaction because crushing the ore will increase the surface area exposed to the chemicals/gases during the reaction in the furnace.
when we were purring molten chocolate in the mold we tap it so that the liquid gets settled all around and the air bubbles go away. dont know about copper but it works with choco 😁
First of all, Thanks for all your hard work and great videos. The most likely source for advice for cooking and pouring would be Jason. He uses a cone mold almost all the time. Large enough to hold all the stuff you are pouring. I've seen Dan Hurd, yourself, Brent Underwood and others pour bars with limited success. The one channel where I saw pretty good results pouring bars (silver) was Rob Finds Treasure. Robs copper bars look like bread also. I'd try Jason first. He helped Brent recently with lead and silver. Best wishes...oh yeah!!!
BigStackD is a channel where he smelts all kinds of recovered metals into ingots in his garage. His results vary, but he seems to use a variety of techniques while pouring, so his ingots vary as well.
Haha!! When the rooster crowed on your video, my rooster heard it outside and crowed back!! He is still going. LOL. I have a mess of copper ore to smelt that I got from the mines up in Michigan's UP. Looking for the best way to do it.
Jeff I remember living in Havasu watching the GPAA channel. Begged my dad to take me. He never did! I’m 38 now, still want to go out and do it. Do you have personal classes? I would love to bring my son out. He loves watching you too!
Get a Propane Torch like a Bernzomatic TS8000 (Swirl flame version) and lay it flat flaming the mould from above while you get the crucible so it keeps the mould heated, and keep it going on the bar surface during and for 4-5 seconds after pouring. Slows the surface cooling of the bar. Same method to get smooth PGM bars
Heating your molds up before pouring would help to get rid of any moisture in/on the molds. Steam generated from that moisture would cause bubbles on the surface. A tiny bit of water will expand into a large volume of steam.
@@darrenbrisson4336 If you have oxides on the mold surface and traces of other salts from previous use you have a potential to hydrate those salts with water molecules. This water is not just sitting on the surface but is actually locked tightly into the salt structure. The humidity in the surrounding air might be very low there but it is never zero. These salts can pull water directly right out of the air. That's how those silica gel packets work to bring down humidity. This " water of hydration " is so tightly bound in the salt structure it can only be freed with extremely high temperatures. Molten metals like copper are at a high enough temperature to explosively release the water as steam bubbles in the molten metal.
If you take your pieces of pure gold/copper and put them into a bar mold and remelt them your bars will come out looking nice. You want to avoid pouring the molten metal. This allows the molten metal to use gravity to settle without any holes or imperfections in the mold.
You might also be to take the mold right after to pour the bar into it and put it back into the kiln or furnace. This way you wouldn’t have to wait as long for the gold to become molten again. And the liquid gold would still level its self off in the mold.
Hie jeff, love the apparent simplicity of you process. Whats the name of the flux and thinner you use and how much would you use per kg of oxide copper ore
Hey Jeff, that’s awesome, always loved smelting. If you get a chance, look up Steetips on TH-cam. This guy is a genius meticulous garage chemist. He shows precise brake down on gold and silver. I think a smart feller like you will enjoy it. Your copper should be 4.3 Oz
2 things for a good copper bar: 1: you gotta top it off with flux when you reheat it, and 2, then you reheat it in the mold [typically in a refractory/heat-treating type oven] and let it sit there at the melting point for 2 hours, then really slowly let it cool back to at least the freezing point before letting it completely cool outside of the kiln/oven.
Professor, I always recommend my friends to watch your videos. Completely professional. I think there was some gold in your copper metal. Is it so? Because when I melt malachite, there is gold in it.
I'm a fart smeller when it comes to smelting jk I haven't even coated my foundry yet and it has almost been a year .many if I find some green rock it will motivate me. Thanks again for the vids
Yes pretty good. You know ive thought about making a bar with depleted uranium in it, to weigh it down, have some other material around it and goldplate it. :P Im no bar maker, so i dont know what to do. But what i do know is that they make rings and jewelry with brass (a copper alloy). Ive seen guy with fluid 3D printers, and vacuum casting having great results. Like VOG (vegoilguy), and Clearmind Jewelry. Im thinking about doing such a thing, and if i get good results, im going to pour it with silver and gold too... Greetings, Jeff
There's something you put in molten copper to keep it from absorbing nitrogen. Grant Thompson struggled with that. I know copper is more common and less valuable, but that color has got to be the prettiest and most unique in the periodic table. It all deserves to be cast into cool steampunk-looking machine parts or something.
Is it correct to fill the crucible with charcoal before melting the copper ore with a little iron, cover the crucible and heat it up? Or is it correct to add the copper ore to the iron pan and roast it before melting it? Advise

THERE YOU GO BOSS!! LETS COPPER!!!!!
In a previous life I sold air pollution monitoring systems to a smelter in AZ. They have some of the scariest smokestacks I've ever been up! 🤠
@@motokenzo763 Intresting, I remember as a kid seeing active chimnies but not anymore! Thanks !!
I think if you heat up your molds the bars will come out better.
Could you use electrolysis to remove the copper
Hey Big boy! It's me Dave from Florida! I love the fact that you are doing videos again, anything you do is cool with me!

thats great Sue, you betcha and you too
Wtf is great bout what Sue said. You fw
Sreetips has a torch aimed into the mould as he pours the metal in it keeps it right up to temperature till the end of the pour.
Copper boils way faster than gold, sreetips melts gold or silver only.
I agree I have better pours and avoid fast cooling I also use a bigger mold it doesn’t have to be filled to the top a 5oz to 10oz molds are nice and they avoid spill over
not really I have been melting and don’t have problems
Heat the mold red hot before and during the pouring, the shock of heat difference is minimal.
Try skimming some of the slag off before you pour.
I used your Parkes process from a long time ago. It worked perfectly
Great to hear!
All these years and you're still making great, entertaining videos :)
thanks
Everybody needs at least one dude like this in their lives
I love this guys energy!

Grinding it up is the answer Jeff.
Was working with copper all day and was wondering the smelting process. Loved the video and answered my questions!
Glad I could help!
Great to see Jeff up and about, don't care none, just the smelting of mental is enough to get my AU boiling.
Very hot mold 👌with a bit of graphite or sawdust to eat the oxygen and stop sticking 👌

The preheating technique is what Sreetips uses on his channel, he usually uses map gas or acetylene
And if you cool the bar slower the wrinkling will be less significant

First of all, Thanks for all your hard work and great videos. The most likely source for advice for cooking and pouring would be Jason. He uses a cone mold almost all the time. Large enough to hold all the stuff you are pouring. I've seen Dan Hurd, yourself, Brent Underwood and others pour bars with limited success.
