Crushing & Panning Gold Ore From Western Gold Mines
Вставка

- Here I crush and pan out a couple of samples of gold ore I brought back from western gold mines I visited on my recent vacations. I first reduce it to pieces with a hammer. Then I crushed it with my jaw crusher. Then I pulverized it into a fine powder using my manual impact crusher and an improvised ball mill. Panning the samples revealed gold, copper, garnets, sulfides, fools gold and possible silver. In a future video these samples will be smelted in an effort to recover the gold and silver.

Find some old dead treadmill and rip the motor and the 2 end rollers out of it. You should be able to rig that up into a rock tumbler big enough that you could fit a propane tank or a bucket on. You could ball mill a lot more material at once that way. Of course you would probably need a lot more balls and let it run for a day.
I built one for polishing rocks and I can fit three of those barrels across it at one time. 2 roll back to back with each other, and 2/3 of the way across, I have a stationary wheel that the third barrel will ride against so it doesn't interfere with the screw lid on the other 2. I also put a stationary roller wheel at each end just to keep everything in place so they don't go rolling off. It's a 90 volt DC motor, but I think I've got mine running on 12-16 volts. It's a multiple tap Transformer and I don't remember what the voltage was that I ended up picking to be a good speed but its fairly low. Just goes through a rectifier and into the motor. It sure makes polishing rocks go by faster when you can fit two small barrels and one bigger one on there at one time.
I have plans for the future. In the short term I am going to get a pneumatic hammer to do the pounding in the manual ore crusher. That should speed things up and make my life a lot easier. Long-term I am working on a flail mill. The future could get interesting.
You should check out Dan Hurd's pulverizer, its essentially a concrete grinder in a metal cylinder. He gets a pretty fine powder quite quickly out of it

Hello Mr Omegageek. I know this comment isn't really relevant to the video, but you have not uploaded any mirror making videos recently, and I need your help.
I'm taking an attempt at making a "telephoto" mirror lens for my DSLR camera. Essentially a miniature Newtonian telescope. However, due to it's objective nature, the plane mirror must sit parallel with the parabolic mirror.
Therefore, I'm tasked with cutting a hole in the parabolic mirror. I've obtained the blank, but I'm unsure whether to cut it right now, with it's full thickness - hell of a lot of glass for my diamond crown bit to chew through, or to cut it once it's been ground to shape, I'll have half as much work but I face a much larger risk of cracking it, right?
Also, I will need to turn those blanks into mirrors somehow. A local observatory offers aluminizing the mirrors for ~$0.30 per square mm, which would run me over $1500. On the other hand, I can try with the silvering kits, which range from $40 to $250 or so. Do you think the optical quality of home silvered mirror can perform well enough for something like this?
Yes, the weather has been bad here for months. Running my kilns during thunderstorms with the power flickering and going out is not practical. So no glass-working videos lately. Normally when coring a mirror it is best practice to core most of the way through from the back first. Then grind and polish the mirror while it still has center support, to prevent any issues arising. Then once the mirror is done, core the rest of the way through from the front, to prevent the core from spalling out at the edges. I'm surprised the coating cost is so high. here in the US coating a small mirror doesn't cost much more than $100, and there are many shops that could do the work.
Very cool, I'm looking forward to that smelting!
Excellent idea the ball mill rock tumbler! What diameter, how many spheres?
Hi Mike, A lot of time & energy spent crushing your ore. Hope you find more gold specks in your pan. Looking forward to the smelting video! What metal do you use in the cupel? Take Care, Jim
Thousands of ounces per ton? Imagine having 1000 ounces a ton ore,id be in heaven lol.
How much does something like that mini ball mill cost?
That looks like it would be perfect for me doing ic chips.
Im exciter for the smelt
Is that gold splatter on your desk?
No, just a trick of the light. It's just crud.
Süper bir çalışma olmuş 👍
If you had 5lb of the sulfides what about of gold might be in it?
I think you would have been better off roasting the powder oar
Lets smeltttt
If you heat the ore up in a fire then drown it in water, it will crush up with your bare hands.
Lol
