A Fire Assay, Chalcopyrite vs Arsenopyrite. Проба халькопирита и арсенопирита. 

Greetings from Russia, from the Bryansk region!👍👍👍✌

Cool process. Enjoyed, thanks for sharing 🤠👍🏻

very Good ❤

Hello my friend, cool process. That would be a good chunk of gold even at 10%. All the best and take care. 👍👍

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.

What is the consistency....ahhh...this is like butter

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!👍🏃🏃✒️

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'm from sudbury and wondering where one could go with calaverite. Or how to go about separating it...???

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?

Nice work. Just getting into hardrock mining. Would a shaker table be a good investment to separate the sulphides after crushing??

Good 👍👍 kalau boleh tau pak..itu tungku listrik brp °C..suhunya 🙏 untuk copelasi.

Ijin bertanya tuan guru 🙏, campuran h2so4 + HNO3 apa bisa melarutkan arsenik , sulfur dan biji besi dalam kandungan arsenopyrit?

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.

Did you use silver free litharge?

How would you separate the silver from the gold in the larger prill?

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

Do you have any idea how to make silica

What is the temperature of the electric oven?

Tuan tolong bikin video tentang ciri-ciri/penampakan batu arsenopirit secara jelas di kamera.biar kita tahu.terimakasih

flux nitrato de potasio y acido borico sin colector ✌

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 !!

What quantities are added to 1000 kg of crushed rock?

Kowi terbuat dari apa

Fair sample of 50 grams each rock?... lol
