- In this video, I assay two different rock samples from two different gold mines. One sample had gold running in chalcopyrite and the other had gold running in arsenopyrite. The results were very surprising!
В этом видео я делаю пробу двух разных образцов камней из двух разных золотых шахт. В одном образце золото было в халькопирите, а в другом в арсенопирите. Результаты были очень удивительные!

Cool process. Enjoyed, thanks for sharing 🤠👍🏻
Hello my friend, cool process. That would be a good chunk of gold even at 10%. All the best and take care. 👍👍
very Good ❤
Professor, your work is excellent and I am proud to be a member of your group. Why didn't you use borax? I usually put an iron rod in the molten crucible to remove the sulfates from the molten solution. Thank you very much for sharing your experiences in Fire Ace or other gold mining methods with us. Thank you. Hashem.
Greetings from Russia, from the Bryansk region!👍👍👍✌
Hello from Northern Ontario
Hello, friend! Great video clip! 👍👍👍I really liked what you do!in support of the channel.
Hi Kevin, very nice to meet you. You talk about your hobby in an interesting way!👍🏃🏃✒️
Тоже рада познакомиться ольга. Спасибо
👍
What is the consistency....ahhh...this is like butter
Wondering what safety precautions you took while working with arsenopyrite in regards to its dust when crushed and arsenic vapors released when roasting and smelting. Have some samples of my own ive been thinking of running and i know arsenopyrite can be quite hazardous
I use a good respirator.
same issue here.
I don’t consider this to be very responsible. A respirator won‘t adequately protect one, especially not with a forge inside and using Pb instead of Os.
And roasting it inside.. I mean - hey, do whatever you want in your house but maybe it‘ll have to be condemned.
That's a lot of Lead. 😬 Do you have the safe means to collect the vapor of Lead, so you can reuse the leftovers of Lead?
No, I don't collect the lead vapor. It is not worth the trouble.
I'm from sudbury and wondering where one could go with calaverite. Or how to go about separating it...???
I would use nitric acid to remove the silver and other sulfides from the gold. Or smelt the ore using a lead collector metal and then cupel it.
Nice work. Just getting into hardrock mining. Would a shaker table be a good investment to separate the sulphides after crushing??
If there is free gold then yes!
@@exploringnorthernontario9627 so in your case cell froth flotation would be most beneficial due to the sheer amount of sulphides I suppose?
@@u2ooberboober I prefer to avoid the sulphides and find free gold through gravity systems.
@@exploringnorthernontario9627 I know what you mean. I just finished my first cupel about 30mins ago. Got a tiny tiny bead of gold from it. It was a fun learning experience but definitely wish I could get free mill gold.
Ijin bertanya tuan guru 🙏, campuran h2so4 + HNO3 apa bisa melarutkan arsenik , sulfur dan biji besi dalam kandungan arsenopyrit?
Very sorry, but I have never tried using H2S04 for that purpose.
Good 👍👍 kalau boleh tau pak..itu tungku listrik brp °C..suhunya 🙏 untuk copelasi.
1150C
Did you use silver free litharge?
Yes, the litharge contained 50% lead and no silver.
How would you separate the silver from the gold in the larger prill?
Nitric acid bath to dissolve the silver into solution and the gold is left as residue. Thanks for the question.
@@exploringnorthernontario9627 cupel pota yerine portland çimento kullananları gördüm beyaz portland çimento olurmu veye çimento yönteminde değerli metal kaybı olurmu teşekkürler
I would put the prill in nitric acid to remove the silver.
I can hear your kiln make a puffing sound which could mean your air source from your air blower is not providing enough oxygen and needs a better flow rate. Maybe you can connect the blower by a hose to the back of your injector and see if the puffing stops. I watch Jason from Mount Baker Mining as well. He uses a shop vacuum to provide his air source with a diverter and ball check valve to adjust the air flow. His diverter can connect to a second injector when he uses his larger furnace that has two fire injectors. It is just my opinion that your wonderful furnace is being starved of oxygen and thus not working efficiently and reaching higher temperatures. I apologize in advance if I'm in error.
Yes, that is exactly the case. I must admit that I have been meaning to do this for a long time. Thanks for your comment.
Do you have any idea how to make silica
Yes, that is easy! Find some quartz and grind it up into fine powder.
@@exploringnorthernontario9627 This is the material used in metal smelting
What is the temperature of the electric oven?
2000F
Here, where do I live? I did not find / ledad flux. Is there an alternative to it?
@@karimrazak3798 You can use pieces of lead as your collector and experiment with various amounts of silica, sodium carbonate, borax and carbon. You can read this link. It has many different smelting recipes: goldrefiningforum.com/phpBB3/viewtopic.php?t=23280
flux nitrato de potasio y acido borico sin colector ✌
Did you just evaporate a gold? But how? Why your heat box looks clean? There must be a lot of red-hot dust that has evaporated from the vessels
The gold does not evaporate. The lead evaporates and is absorbed by the cupels, leaving the gold and silver.
@@exploringnorthernontario9627 but what about anothers metals, in particular a copper from chalcopyrite, why it didn't leave?
@@user-fp8xb5tb1o The copper was absorbed by the cupel along with any other base metals, leaving only silver gold and PMGS.
@@exploringnorthernontario9627 Thank you for answers, have never heared about that before. Great videos :)
Tuan tolong bikin video tentang ciri-ciri/penampakan batu arsenopirit secara jelas di kamera.biar kita tahu.terimakasih
Kuring teu nyieun video anyar leuwih ti 1 taun. Kuring miharep sangkan leuwih usum panas ieu.
Are you serious ?!! You can work just on that arsenopyrite getting at least 5 grams of gold daily/ 1 kg !! Get a furnace, crucible 4 .. crusher .. roast and smelt .. I cant believe you didnt do that !!
Kowi terbuat dari apa
What quantities are added to 1000 kg of crushed rock?
For this amount, I would not use a lead flux. I would rely on the gold and silver content to be my collector metal. You would have to experiment with how much carbon, silica, and borax to use depending on the type of ore you are using.
How much borax and carbonate do I put?
@@karimrazak3798 As a rough estimate, I would say you need to add 50% to 100% carbonate to ore ratio. So, 500kg to 1000kg of carbonate. The amount depends on the PH of your matt. You can start with 500kg and if it boils violently you can add more to neutralize the PH. As for borax, I would use 250kg -350kg. Too much borax and the flux gets too thick. Don't forget to roast your ore first.
@@exploringnorthernontario9627 I mean. 1 kg. (1000g)
What materials are in the crucible with ore?
1=.....
2=.....
3=.....
Fair sample of 50 grams each rock?... lol
