Thanks!

Hi James. I have a video showing how I made this rock crusher here: th-cam.com/video/YDCOWNoyT1A/w-d-xo.html But I have since made some modifications and posted an updated video here: th-cam.com/video/Cm67cGC86E0/w-d-xo.html

@@danielflinn3571 Thanks for watching!

Bạn cần những công cụ nào?

Tôi cần công cụ ở đầu video bạn nghiền đá thành bột​@@LetsCrushRocks

@@ronglol552 Máy nghiền đá là một công cụ mà tôi tự làm. Sau đây là hai video tôi hướng dẫn cách làm: th-cam.com/video/Cm67cGC86E0/w-d-xo.html th-cam.com/video/YDCOWNoyT1A/w-d-xo.html

I can try to find the exact flux recipe I used in this video and will post it here if I find it.

I try to keep the videos short because I know people have short attention spans. I will try to show more of that in future vidoes.

Ya these were really nice with all of that visible silver. I'll be making a few more videos processing the different rocks from this box!

I'm not sure how I could translate the video into Turkish!

Haha, I would be happy if it could be translated to polish. Well everyone wants something... Be happy you get to watch it in international language.

@@stasi0238 That sounds like a lot of work!

@@hunnybunnysheavymetalmusic6542 I've still got to build a little flotation tank to concentrate my lead and zinc ore samples. Lots of galena and sphalerite in the shed.

@@hunnybunnysheavymetalmusic6542 I've got plenty of sulphide samples to make future videos with!

I just kind of wing it. I generally want a total of about 2-3 times the weight of flux relative to the sample. So if I have 100g of sample I usually want a total of 250g to 300g of flux. If the sample is very rich in sulfides, I add a lot more soda ash relative to borax. The sulphides create an acidic smelt, and the soda ash is basic, so it balances the pH out. If it is low in sulphides than I do more borax relative to soda ash so the borax can keep the melt less viscous (so it is not so thick and sticky, flows better and allows the lead to collect precious metals better and settle at the bottom). If there is not much silica in the sample, I will add 20 or 30g of silica. If there is lots of quartz in the sample than I don't both adding any silica. I usually go with about 25g of lead as a collector metal to pick up the precious metals. Less than that and you risk not having enough flowing around to collect everything efficiently. More than that and you need bigger cupels and longer time for the cupellation process. I recently purchased some manganese dioxide to help oxidize sulphides, but I haven't had a chance to try it yet.

Thank you! Cheers!

Thanks! Cupelling this I think took around 45 minutes. But the lead doesn't exactly vaporize. What happens is in liquid form the surface of the lead oxidizes very readily from oxygen in the air to form lead oxide on the surface of the lead puddle. That molten lead oxide then slides off and gets absorbed into the cupel. And this oxidation/absorption process happens over and over until all the lead is gone. A small % of the Pb does get airborne, I think 95% or more is absorbed into the cupel.

@@LetsCrushRocks Thank you. You are really creative and skilled in your work. Good results.

@@abdullahnaveed6699 I've got a few silver videos coming out soon, just have to edit the footage. I have a few good copper samples so I'll process those next!

Next time I'll try panning inside to see if that helps!

The reddish colour is usually iron pyrite oxidizing to iron oxide during roasting. So it is a good sign that there are iron minerals in the ore, and gold is often associated with iron!

Thanks! The time it takes to cupel all of the lead away depends on how much lead you start with. A good rule of thumb is that it will take about 10 minutes + 1 minute for each gram of lead (so 30g of lead would take around 40 minutes). But that depends on if the lead is getting good access to oxygen. In my furnace in this video it was hard to ensure good oxygen flow. But I now use a different set up that blows air into the furnace and it cupels much faster. For roasting, once it is up to temperature it shouldn't take too long. Maybe 10 or 15 minutes if it is spread out in a thin layer, and stir it up a bit. Just wait for it to stop smoking and for it all to change colour to know it is done.

@@LetsCrushRocks thanks bro 🙏🏻

Ok, you did, still watching 😅, imagine when the ancients had gold rich ore rocks in their camp fires the gold pouring out.

@@dav1dbone I'd be curious to know at what point in time humans started to extract gold from ore instead of just from placer deposits.

I've been using an iron rod in my more recent smelts! it helps!

show us what it looks like when its done!

@@LetsCrushRocks I would love to. I've got my parts for the most part. Just trying to decide how I want it to work going forward

@@24KGOLDRECOVERY thanks!

Thanks!

@@durtyt4770 Awesome, I'll give that a whirl. Thanks!

Thanks, that's a good call! That would be a lot faster. But I have since added a feed/extraction port at the top so I just drop the rocks in and then tip it upside down to dump out the crushed material.

That's actually how I make soda ash (sodium carbonate). Just take baking soda (sodium Bi-carbonate) and still it in the oven at 200F for about an hour. I'll look into that for borax, though I seem to recall seeing a video where they said you had to actually get it to melting temperature to reduce it, then pour it out, let it solidify and break it up again. Quite a bit of work!

Gracias!

Thanks! I got the bearings from Princess Auto in Canada (C$14.99 each) www.princessauto.com/en/2-bolt-standard-duty-flange-mount-bearing-assemblies/product/PA1000001323?skuId=3870177 You can get them on Amazon for a similar price, sold as a pair. www.amazon.ca/PGN-UCFL202-10-Pillow-Mounted-Bearing/dp/B07W7LHWTM/ref=sr_1_2_sspa?sr=8-2-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1 The Princess Auto ones have a bit of a void space behind the bearing that I don't like. I can't tell from the images of the PNG bearings if they have the same space or not.

If you are in Canada and looking to buy a steel plate, I found this one at Princess Auto that was the cheapest option: www.princessauto.com/en/12-x-12-x-3-16-in-44w-plain-steel-plate/product/PA0009055120

@@LetsCrushRocks Thanks so much!

So I can get the gooooold!

I've seen others where they have an outlet port that drops into a bucket with a sealed lid. The lid then has another outlet tube leading to a vacuum so the material drops in the bucket but the dust is drawn out of the top. I think I might give something like that a try! Thanks for you thoughts on the wobble. I might look at chopping some of that extra bolt off! Cheers.

@@LetsCrushRocks I like that bucket idea for it. I've been trying to figure something out for mine and was coming up empty. So thank you too.

Good idea! I later thought of putting plastic wrap around it too.

Just sent you a LinkedIn message.

Thanks! No visible gold in this one. I'll have to smelt this sample to see if its got any gold hidden in the sulfides. But I have boxes of rocks from all sorts of mines that I have been meaning to crush up and process. Should be a fun season now that the weather is good for working outside up in Canada.

Thanks! I'm just finishing a few modifications to it now and should have an updated video out in a week or two. And I promise the next video won't be so long-winded!

You could get the temp that high, but I dont know how even the heat would be. I haven't done anything with pottery before but I would guess it needs to be an even heat. You'd want to elevate the clay in the furnace to make sure the flame isn't hitting it directly at the very least. (I had to Google what "raku" was by the way).

@@LetsCrushRocks Thank you so much for the quick response! Oops, I guess should have said what raku was in my original question...lol. I know people raku fire pottery in a LOT of different home made kilns and heat them with propane, so this seems like it would work to me. I think my only concern is if the heat ramp up can be controlled? I would not want it to go from ambient temperature to 1950 F in 10 minutes 😅

You could adjust the gas flow with the valve and the pressure regulator to help with some temp control. You can also leave the lid off to start with as things are heating up and then put it on later, I do that when I first start up the kiln to drive out any moisture since it since sits in my shed often for months without use. I should probably get around to uploading an update video. I ended up changing my design a bit... stay tuned I guess! @@amyrp9115

I appreciate the help and just subscribed! I will stayed tuned 😉@@LetsCrushRocks

Thanks man, glad your build worked out! Great idea with the pressure cooker. Cheers.

Do you have a video of you making or using your crusher I would love to see it

@@caseybeckner2625 Working on that! I have a Short video up showing me use it to crush silver ore. But I need to post a longer form video of the crusher showing additional changes I have made to it recently. Hopefully I will have that soon!

me too,same country!

Thanks! Posted an updated crusher here: th-cam.com/video/Cm67cGC86E0/w-d-xo.html

Thanks! Finished some improvements on it, just wish I had more time to use it!

You mean have two chain links linked together on each side? I would have to make a much bigger crusher housing to accommodate the extra diameter. Might also be too much work for my little angle grinder to power something of that diameter as well, but perhaps not.

Yes@@LetsCrushRocks

I don't think I would bother with the outlet port and just load from the top, crush, and then turn it upside down to dump out. The large washer in the middle used to hook on the chains is weak and bends after a while, eventually breaking. I have doubled it up but it still bends. Would recommend replacing it with something thicker. I don't have a drill press so its hard for me to drill large holes through thicker steel. I saw a recent build video by Orophilia that was really good, he makes a nice crusher.

@@LetsCrushRocks thanks alot. i made a steel flailer to make solid steel stair ballisters look handforged, there was alot of trial with errors but i got it done and its useful for beating alot of otherstuff also!Pierre laboom, ""browns finally stair ballister basher"
