You are most welcome. There are also some on speed propecting hard rock using this technique.

Thank you. The newer procedure is easier.

You're welcome. Been studying in the School of Hard Knocks and Rocks. :-) While the principles are simple, reality makes things complicated.

Wow! Just saw this one. Thank you.

Thank you. I think you will find lesson 24 (The new and simpler method) even easier. Keith

Thank you

Nice

Make sure to watch lesson 24 for the improved version.

I'm very glad I was helpful. That is what I do this for. Keith

You're very welcome. The technique is specialized for gold less than 50 mesh. Coarser gold does better with a conventional reveal.

I'm glad to have been inspiring. Now for some practical advice passed on to me by a PhD: Major in the broadest field that adequately covers your field of interest but study heavy in that field. In my case he said not to major in extractive metallurgy if I went back to school, but material science with a focus in extractive metallurgy. Mining goes in decades long cycles and if you are looking for a job in a downturn, you can get one easily somewhere else with the broader major while still being well qualified for what you want in a good job market. Nothing stays the same. Be able to adapt when needed. GL to you on your studies and career.

Thank you. A simpler method using the same principles is the latest version kzfaq.info/get/bejne/f7Z1iK2Czp2RfJc.html

Make sure to look at lesson 24. I made it even easier.

You are most welcome. Good luck. Also check out the "Speed Prospecting" videos to see it in use.

You're welcome. Make sure to check out lesson 24 for the simplified version. BTW, this ONLY works on fine gold. The coarse gold slides to the near side of the pan. I am working on a method that recovers everything at the same time with one procedure.

I think if you just click on the HardRockUniversity Icon in front of a video it should take you to my channel. They are all there. Most are also accessible on my web site HardRockU.com without any competition from KZfaq. I also have some other interesting stuff there. Glad you like them. Keith

That link is no longer working.

Thank you. Education as opposed to entertainment.

+konartist206 Thank you. Been busy lately. Hope to have some more soon. Keith

Did you see the new technique in lesson 24? Keith

You're welcome

Glad to help. Thank you for your blessing. Keith

Thank you very much for the kind words. Eventually I plan on having actual field training for sale. Ten hours for 5K is too much IMO though

You are most welcome. It comes in very handy at times.

Glad to help. I am using the process to test some ore we got in CA this week. I am then going to run the good bulk samples over my table today. For every 64 lbs of sample run, each 1 gram of gold recovered is equivalent to 1 Oz/t head grade.. Should be sending the owner a report later today. Keith

You are most welcome. I am finding the technique extremely useful now that I figured out how to do it. It's really nice to be able to get a rough assay in minutes. Keith

Thank you very much. Heading back out to the mine this morning for another three day trip.

@@hardrockuniversity7283 You are welcome. And Good Luck. 👍 I wish, i can find *"Good Gold"* soon too.

You want to try the new method- it's even easier. kzfaq.info/get/bejne/mqudodVmyLyWiWQ.html

You are most welcome.

Thank you. If you have any questions, just ask. Keith

Thank you. Sorry about the delay in responding, I never got as notification. You might want to check out the newer and easier technique in lesson 24. Keith

Thank you, I hope the information is useful to you. You might want to look at lesson 24, lesson 28, and lesson 30 for even more information. Keith

Hard Rock University Im whachin every lesson

I'm glad you find them useful. If I may ask, where are you from? I think I detect a translator program. Keith

Always trying to help someone make that breakthrough. Good luck!

I've been sampling different areas in Central Queensland Australia and now seeing your tutorial I realise I may of missed some very fine colour. Hopefully i won't now!!👍⛏⛏⚒

Be sure to watch lesson 24 for the easier way to do the same thing.

Thank you. Let me know how well it works for you. Keith

Make sure to view some of the later videos on panning micro fine gold. I have learned a lot over the years.

Thank you, keith

You are most welcome.

You're most welcome. Good luck! Keith

Thank you. Don't miss lesson 24 also as it has a simpler method. Keith

You're welcome. Is it working well for you? Keith

Where are you living? Have you watched the other videos listed in the description?

It is not that difficult, just DIFFERENT. Ore runs about 1/3 oz/t

You might want to check out lesson 24. I found out how to do it even easier. Keith

And extremely useful

Thank you.

You're welcome. This is a very useful and easy skill to learn. Lesson 24 shows you the latest method which is even easier. Keith

I would recommend lesson 24 also. It is a modification that is faster and easier. Keith

You're welcome. Make sure you look at the newer and easier versions listed in the description.

It is always good to double check. Micro fine gold is even tougher.

Can you please tell me the clarifier you use? How much of the Jet dry do I use as far as a water to jet dry ratio? I really love and appreciate your video. Thank you!

Watch video 24 improved hand panning.... No wash bottle required.

You're welcome. I never got a notification on this, just noticed it while going through video by video. Keith

Here's the link to the lesson on recognizing gold: kzfaq.info/get/bejne/odKgldyg3Zusmmw.html How much micro fine do you get? If the concentration is high enough, it can still pay well. You just need to use different extraction methods.

Are you sure it isn't biotite mica? It can look very much like gold, but it behaves entirely different in the pan.

@@hardrockuniversity7283 funny you should mention that I am about to watch your vid on gold - fools gold! I am not sure but it was heavy enough I could somewhat separate it with my clumsy technique. It did sink in water except in the stream I found it, that was almost whitewater it ran so fast. This was right below Deer Lodge in Montana and I got excited finding out that was the area gold was originally discovered in MT in the 1800's

@@hardrockuniversity7283 There was a lot of black sand present. I also noticed A LOT of stones which I disregarded unfortunately. Red and green crystals, which I found out rubies and emeralds were not uncommon in that area

@@hardrockuniversity7283 I do have to say I am surprised you are still on after so much time and honored and grateful you replied!

@@robertkamenoff3918 Gold will behave quite differently than Mica in a pan with mica disappearing early on and even fine or flaky gold hanging in there and either mixing with the black sand or lying under it. Even with a lack of experience it should be fairly simple to identify mica. Chalcopyrite can be a little harder.

Not sure of the exact chemistry. It was a commercial pool clarifier sold at Home Depot.

Thanks for the compliment. If you ever have any questions, just ask. My thumb was fine :-) . I do construction also. Tomorrow I'm grouting tile for eight hours or so. Keeps me in shape for a 60 year old geezer. Keith

I think NH is New Hampshire, but what is 'fine BS gold'?

That is correct. As you move the pan side to side while tilting away from your hand, the light materials travel across the bottom faster. At the bottom of the charge closest to my hand will tend to be a line of heavies- including the gold. By not letting the wash water get up that high, you protect the heavies while washing out the lighter materials. At 4:15 you can see the line of heavies I am talking about. You might also want to look at lesson 24 for a simpler method of getting the micro fine gold.

If they are true tellurides you cannot use gravity methods to separate the gold. You have to use intermediate steps or alternative methods. Here is an article that goes over some of them. www.911metallurgist.com/blog/metallurgy-recovering-gold-telluride-ore#gsc.tab=0 I am not personally familiar with tellurides. What is the ore grade? Keith

You have to be careful not to entrain particles between the black sand particles. I usually wait till near the very end if needed. Until then, they kind of 'protect' the gold. At least so it seems to me.

Hello, I can see there may be problems with language so we will go slowly and carefully. To start with I would suggest you view lesson 8 and lesson 24. Lesson 8 will show you some of the ways to identify real gold from fools gold and lesson 24 shows a simplified version of this panning technique that works much faster and easier. I am assuming from you message that you have fine (small) gold in sand or gravel and you need help identifying it for sure and recovering it if it is really gold. Let's take the easy one first: gold behaves differently in the pan from other materials because it is so dense. It really likes to stay where it's at and moves more slowly than similar sized particles of anything else. Almost all gold in sand and gravel (placer gold) will be yellow and all will be dense. Because of that any shiny yellow particles that resist movement better than everything else in the pan are almost certainly gold. The only natural mineral that would be easy to confuse it with is chalcopyrite (CuFeS2). Even then, the difference in density is obvious to an experienced panner (which I assume you are not). Therefore a second easy test is possible: Take some of the yellow particles and put them in a spoon you can dispose of, heat the spoon from below with a torch until it is glowing red, and keep it glowing for a few minutes. Chalcopyrite will quickly oxidize to a non-shiny material- usually brown- with the smell of burning sulfur. Gold will not change at red heat. How much yellow material is there in the sand? Is any of it big enough to try to flatten with a hammer? Keith

Uh..., this is 500 mesh or so. You might also look at my 'speed prospecting' videos for hard rock to see the application.

Happy to be of service. Unfortunately my main job seems to be limiting losses instead of maximizing profits.

It is very ore dependent. They both have their strengths and weaknesses. That is why I am trying to develop my own design that works differently, but with similar physics. The variables are Throughput, Recovery %, and Purity of the cons. Every ore is different and each must be tested to determine the best technique. Annoyingly complex- but interesting.

I used to buy the 'Pool Clarifier' sold at Lowe's by the gallon, but it is no longer available in the gallons. On my trip, I ran out and in Oregon neither Lowe's or Home Depot. had pool chemicals, but WalMart did have Chlorox brand. I haven't tested it yet as I never had a true production run to get through. Whatever you try, make sure to test any effects on recovery with YOUR ore.

If they are sulfide cons, why not? It should free up the gold. Sometimes fine pulverization and gravity works well, sometimes roasting first, and sometimes you need to pulverize and then leach. It all depends on the ore. Sorry for the delay, I got no notification. I'm just going through my channel video by video to see what I missed. Keith

I would expect it to be wider, but about that long with my technique. He might have forced it more into the corner of the pan.

The problem if frequency and amplitude. In wet panning, high frequency and small amplitude gives packing. Low frequency and large amplitude gives liquifaction. Been there, done that. Good idea, just doesn't work IRL. Keith

That is crushed hard rock ore with no concentration. Analysis of the ore showed no significant arsenic. What situation do you have? If you can describe what you are dealing with better, I can give you better advice. Have you done any laboratory tests? Keith

Hello, Thank you for your answer. Yes i have a laboratory tests! i have in 1 Ton Arsenic 131 gram Gold and 74 gram Silver! Regards.

Well, that means you have about $100 per ton entrained value. To make a profit you must be able to mine and process the rock for well less than that. That would be very difficult for an undergound operation, but possible for a surface operation if the rock can be efficiently open pitted. What is the general size and shape of the formation? Keith

I can send you some Videos and Pictures from or mine but that is here in youtube not possible! if you agree, i write you my email adress and you can me write back. we have 131 gram Gold in 1 TON ARSENIC ORE, i think that is more as $100 US DOLLAR. Thank you for your answer and effort Regards

I thought that was 1 and 31/100 grams gold. One hundred thirty one grams is a whole lot different! Does "In one ton arsenic ore" mean "In one tone of ore that also contains arsenic"? or does that mean "In one ton of arsenic concentrates from the ore"? Either way it should be easy to come up with a profitable flow sheet. You can email me at hardrocku@outlook.com

But then the guy holding the nail would have a blacker finger nail! :-)

The translation is a little confusing. Are you asking how to determine the size of the gold particles in the pan?

@@hardrockuniversity7283 Yes , Sir the size and the color...I meant by brown stuff.. which I saw heavy brown grains under iron I used magnetic, the brown grains appear under iron

There is too little information for me to be sure. If it is brown, it is most likely to be some form of iron oxide that is NOT magnetic. Some oxides of iron are magnetic and some are not.

@@hardrockuniversity7283 I'm very sorry to disturb you 🙏🏻 Actually I'm New student in this... I don't know what is the gold colors in panning dish very sorry teacher .. health, wealth for you

No problem at all Mohammad. I like teaching. Gold will look like clean brass. A gold/silver alloy (called electrum) can be pale yellow to silvery. You can practice your panning technique by mixing metal shaving with dirt and then panning down to the metal. It is much harder to learn if there is nothing to separate and identify.

about a dollar at today's prices

what are the dimensions? I'm guessing fine to micro fine. There tends to be a lot of other stuff to separate the gold from in electronic scrap, so they usually use a wet chemical system. There is a book "Recovery and Refining of Precious Metals" by C. W. Ammen that is very thorough including an entire chapter on 'Recovery and Refining Values From Secondary Sources' that addresses the issue in complete functional detail. It's a bit pricey, but well worth it. Keith

Their diameter can range from 15 micrometers to a few hundred micrometers. On average they are 1mm in length. I am thinking about incinerating the chips to ash then panning the gold bonding wires. Using acid or cyanide is out of my comfort zone.

Well, you can certainly try that. n My concern is that there may be some other metallic particles that might be hard to separate. Why don't you give it a go and let me know how it turns out? Keith

Are you anywhere near Tucson AZ?

You are most welcome.

Very fine gold can actually float on water. Gold, like many metals and sulfide minerals tends to repel water like a freshly waxed car. Because of this a small gold particle can get on top of the water and float there. This lets it literally float away. Jet dry acts like a detergent to make the water 'wet' the gold and keep it under water. Dawn dish washing detergent does well also but creates more suds (bubbles) that cause problems during the final steps. Gold large than 100 mesh usually doesn't float, but can if it is coated with oil. For that reason you want to keep oils and greases away from your ore and process water. Was that clear? Keith

Hard Rock University yea thankx

Hmm. I'll have to try that sometime. Thanks.

Thank you

It is a pool clarifier found in the pool chemical department of Home Depot.

Yeah, dawn has its limitations. With this, I can keep the suds enough under control to do the preliminary panning, but I can see how they would quickly get out of control on a wheel. Did you try jetdry?

It definitely should be tested. If the ore has both gold and pyrite, you are almost certain to be correct.

Thank you for the feedback. It was one of my first videos and I am getting better. You might want to check out lesson 24 which is the simplified method of panning micro fine gold. Keith

There are gold tellurides. To what do you refer?

About 2/10 Ounce per ton

I primarily use this to test samples for total gold content. For example, it works well for what i call speed prospecting where I am testing the samples as I am taking them to quickly focus in on the best material. In that situation it takes about 5 minutes per sample. kzfaq.info/get/bejne/r71gabJ8qMnXmGg.html When cleaning dredge cons in Idaho the fastest method was a secondary concentration with a gold cube (no detectable losses) followed by hand panning to a clean concentrate which took about half an hour more. Wayne had the best cleanup panning. kzfaq.info/get/bejne/hMCfiLiaxq_eooE.html That gold was very flaky and hard to clean up.

The pyrite will end up lower in the pan than the gold when done properly

It is amazing what can be done sometimes.

A chemical that causes small particle to clump together and sink to the bottom to clear the water.

@@hardrockuniversity7283 thank you. What is a good one and where do I buy it. And thank you again.

@@daviddorger6916 A good pan? For this task, I use the Stansport 10.5" pan sold at Sportsman's Warehouse. less than $5.
