Good morning, just to inform you that when you are going to generate a basic slag in the foundry, you must use basic crucibles to prevent the attack of the slag to eat the crucible, you must use magnesia - chromite crucibles with the following characteristics: MgO 62.5% - Cr2O3 17% - Al2O3 6.5% - Fe2O3 11% - SiO2 2%. As a general rule, if the foundry generates a basic slag, basic crucibles should be used (magnesia - chromite) and for foundries that generate acid slags, acid crucibles should be used (High alumina - silica) which has the following characteristics: Al2O3 70% - Fe2O3 2% & SiO2 28%. In the particular case of sulfide ore smelting if you are going to generate basic slags, just make sure that the crucible is basic base (magnesia - chromite) or if you use acid crucibles (Alumina - Silica) you must change the formulation in such a way that you generate an acid slag, I recommend the following formula: sulfide ore: 130 grams Borax: 80 grams Soda ash: 124 grams Silica: 7.12 grams Lead: 38 grams o 41 grams fo litharge. Charcoal: 2.5 grams To determine the amount of iron I suggest weighing the iron bar before and after melting, the bar should be cold at the time of weighing, the difference in weight would be the amount of iron to add for that mineral. I hope you find the information useful, thank you for your attention and have a nice day.

I think the molten lead needs to be able to "breath" so all the base metals will be oxidized
@mbmmllc4 жыл бұрын
The lead needs access to the oxygen for the reaction to take place. When I open the door it looks like lots of fumes because the furnace is flooded with O2, but when the door is just cracked no fumes come off because there isn't enough O2 for the lead to "burn". Over 99% of the Pb goes into the cupel during this process if done correctly.

Good stuff, I've learned a lot binge watching your videos over the last week! Just to be clear, this method does not work with iron pyrites, they would just be absorbed into the slag along with the FeS created by the iron bar+sulfur from the copper, lead and arsenic sulfides, right?
@mbmmllc4 жыл бұрын
Actually this does work well for pyrite. The iron bar does release some metallic iron to convert everything to FeS (iron pyrite is FeS2) any gold will be released and collected by the collector metal

@USMiner4 жыл бұрын
@@mbmmllc I'm still trying to wrap my head around this in the case of iron pyrite, could you explain the process a bit more. What is happening to the FeS2 during this process? Is it decomposing thermally into FeS during the start of the smelt, or is it being oxidized by the Lye or somehow snagging an O atom from the Borax? If it thermally decomposes to FeS, how does it release any gold contained before being absorbed into the slag? I can see the iron bar taking up the spare S atom, but wouldn't gold still be locked up in the sulfide if it wasn't oxidized by something during the smelt?

A bit worried about that respirator description. A P100 is just the particulate part of the filter. It does protect from fumes, not vapors. SO2 is considered a Vapor. The difference is apparantly how the metal or chemical behaves. Is it still particles or not... Your filters are pink so i assume they are 3M's 60929S P100 combined filters for Mercury Vapor/Chlorine/Sulfur Dioxide Gas and particulate. Not just P100 filters. Please guys be safe, do not use a normal P100 filter for this. It will not stop any gasses unless it is a combined filter made for the task.

Why did you move away from the sodium carbonate for this method? The sodium carbonate has a pH of 11.6 and caustic soda has a pH of 14.0. They are both very basic and should work the same right? The sodium carbonate would be a safer method and looked like it worked in your previous video on this method.

Good question. I have a video coming out soon describing the difference in detail, but essentially with the soda ash a bunch more material needs to be drove off and it tends to boil and froth in the crucible.
