I love GF ! I run a few hundreds of lbs of GF a year. Those residues i capture from processing are saved and processed at the end of the year. There will be karat pieces. Silver chlorides. All kinds of stones. Those residues from the filter papers will contain activated carbon and will contain gold residues. There's a special process for all the residues i have developed over the years. They add up! The silver is and added little bonus also. I offer 95% accountability on recover. The other 5% is mine down the line. Plus the silver is free besides the gold residues. Then there's the processing fee on recovery after that. Gold silver pro taught me that GF is a poor mans treasure. Great show of processes brother!
My wife bought two big boxes of junk jewelry in the dark at a yard sale Saturday morning. We picked through it and found nearly $3k in karat gold. The seller knew there was gold but was too lazy to pick through it. He wanted twenty bucks for both boxes. My wife offered $15 and he took it. He told her, “there’s probably gold in there.” People are clueless about gold.
@@sreetips wow! Nice find. I find karat gold mixed in with GF pretty often. Most folks have problems identifying the difference. It got to where i can pick it up and feel the weight and look at it and know 99% of the time what it is.
Being able to correctly identify what you got is key. Some pieces can still fool me. But after looking at the material day after day for over a decade, it almost becomes second-nature.
Around $1400 worth of AU....plus $500 for your stamp of approval..... Then throw in a $100 respect note.. so theirs $2000+ Thank you for teaching what once was a underhanded screw everyone secret... That the refiners kept quiet..... I've said this before and I'll say it again... You are the first person 2 show this.... and many different precious metal recovery secrets... Thank you for teaching your method....bravo..
Another tip. After you do the two hot hcl washes on the first drop wash it twice with cold water. Then do two COLD washes with hcl. Let it sit about 15 minutes each. Then cold water washes twice. Then a hot wash. The cold hcl will absorb way more silver chloride eliminating most if not all silver chloride problems you are seeing in the 2nd run filtering steps. The hot hcl washes are missing it.
I really like how informative your videos are. I have a friend with a hard rock gold mine, just a hobby set up. The processes and knowledge from you videos have helped so much in processing the smelted ore......can't thank you enough for providing this kind of information. Been watching your content for few years. Only thought it was for my personal entertainment, however it really helped with issues like removing lead from solution and getting better recovery of precious minerals. Thank you and always enjoy your content. Also thank you for your service!!
If i may offer some advice. The copper you got from the silver came from not washing correctly in the funnel. After the hot water washes and while the silver is still hot disconnect the vac from the funnel. Empty the funnel of the used nitric because now you have chlorides coming. Then wash the silver with warm hcl allowing it to soak and sit it the funnel for a few minutes with no vac. The hcl won't harm elemental silver. Repeat twice. Wash with hot water a couple times. Try that. Use with all you silver powders.
It's always wonderful to see what you end up with and the fine gold you get is always so beautiful in the bars and buttons. Amazing that you got 8 grams more than expected. 👍
Amazes me every time just how much work goes into refining this stuff. Here in the UK the cost of chemicals and the gas to run the torch would be way over the value of the end product.
43rd! Love your channel! Finishing stage! YES! It amazing to watch what comes out of your chemical solutions! The finished product is fantastic! Roger in Pierre South Dakota USA
I have a question as well as an idea for another episode. You appear to be very precise and neat… How did your walls get so splattered? You could do an episode called “how much precious metals is stuck to my walls?”
i did notice at a point on the video, i thought it was metal/debris on the beaker, but it was the splatter. There have been some boil overs on the channel. plus, it may have been a used hood, so it might not be his mess.... but i noticed it to. :)
I always wonder if Sreetips will do a "Garage Sweeps Refining" video. From all the stuff I've seen flying out of beakers, buckets and melt dishes over the years.
dude i love that you made a salami look like copper but filled it with silver here my friends is chemist and a magican all in one :) on top of that he never gives up even when someone puts hardmode on without telling him. ps non english speaking native and on phone
the sodium metabisulfite is some sort of miracle, the first time you dissolved the gold the solution was green but the SMB only precipitated the gold and the green stayed in solution, then the second time you dissolved the gold the proof was that this time it was the expected orange color. wow. incredible.
Your GF videos are some of my favorites! I’m curious if you could treat that silver/copper button with a small amount of very dilute nitric acid. Will that preferentially dissolve the copper mostly leaving the silver alone? I’ve also wondered if treating your silver shot the same way before running through the silver cell would up your purity and allow you to get three cycles out of a batch of electrolyte. Just an idea, I’m not a refiner.
Awesome bar at the end there! Don't blame you for not chasing after the undissolved pieces - but that might have added another 2-3 grams or something? Either way, really beautiful bar at the end! 👍👍
I really think I'm getting the gist of this. I know there's a lot more to it than just recovery and refining such as dealing with waste, safety, cleanup, and equipment but at this point I think I could do a run and I'm really thinking about it small scale.
I used to do reactions outdoors. When adding reagents I’d approach from the upwind. As I got close the wind currents would wrap around my body and pull the dangerous fumes towards me. Even after turning and walking ten paces I could still smell the fumes, in my hair, clothing, and in my eyes. It’s repeated chronic exposure of small amounts of these concentrated vapors that will cause big health problems. No way to safely do these reactions without a fume hood to draw the fumes away.
@@sreetips Understood. If I were to make an attempt I'll put a priority on some kind of ad hoc fume hood. It doesn't look like a complicated thing to build. Doing foundry work, I bought a gas mask with NBC filter but I think the stuff you're working with could get into the skin and blood. I won't mess around about it. I won't proceed if I can't get 100% ventilation.
@@heliarche outside in a pinch (not with dangerous gasses but with nuisance gasses and dusts) you could try using a large electric fan to blow the fumes away from your person. Just a thought
A few months ago I was melting some old jewelry in a crucible And a few days ago I looked at the crucible and it had diamonds stuck in it I was like WOW. I wonder how much gold or silver or diamonds left people have inside there crucibles after there Experiments
Hi, Sreetips, great to watch your videos. Thanks for creating them. Can you / or do you recover any acids used in the entire process and/ or in the gold waste from your rinses?
Have you ever considered going down another route when refining such scrap? For example the electrolytic method is much less wasteful and consuming. It also feels less labor intensive, because most of the action happens while you are not there. Similar to silver cell. Melt the stuff down (removing steel parts is good and reduces waste solutions further, but is optional), cast into anodes, and dissolve them in a fairly concentrated copper sulphate/sulphuric acid solution that can be reused many times (when steel is removed) using electricity. Sell the recovered copper for some extra pennies (it pays for the electricity) and recover the precious metals as anode slimes.
@@sreetips I got the fundamentals from this video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kQSymhh8HcU.html I recommend using a more efficient current source, but it works like that. Can be scaled up very easily for large amounts. What is the carrier metal of gold filled stuff? This electrolysis works best, when it is mostly copper.
Surprised to see the electric furnace, neat. I wonder at times, why not use hydrogen to cement the metals, would generate less waste and as far as i remember it comes out with higher purity. I'm a bit baffled the silver and copper didn't alloy. Also, I feel the washes would be easier if you left the gold in the recipient you use for filtering and do the precipitation.
Definitely know nothing about this stuff, just love watching your videos... could you have started out with cupellation to separate out the silver and gold from everything else and then add sterling silver and recovering the gold that way?
Is pure silver softer, in an anealed state than sterling silver? I'm curious to know if the aloying elements in sterling make it more or less workable? I use silver in my knife making and am curious to know which would be a more workable material.
i have to wonder... i don't know IF this is getting too personal but how much was spent on attaining the gold scrap in this process? Amazing video in any case... double thumbs up brother!!
That's a tasty looking bar 🤤 Also is there a difference in weight between the solution when it has gold in and the same amount of solution but without gold in?
Do you think the copper colour/layer is due to copper oxidation on and otherwise pure silver, I know copper oxide is one of the harder ones to get rid of when cupeling
If you simply melted the gold-filled scrap and made golden cornflakes by pouring the molten metal into water and then dissolved the metal alloy in nitric acid would it be effective and economical? The idea being to use base metals to dilute the gold content like in inquartation. The idea is to create a gold sponge and plenty of base metal solution for the silver jar or stock pot.
18:05 - my GOD that pink hue is incredible. While I have some familiarity with processing gold, I'm less familiar with other metal processing... what causes that incredible shade?
hi sreetips. always fascinating and educational to watch your videos. if we don't have a furnace, will the incarnation step work with a propane torch? thanks!
Have you ever just had a slug of gold mud slide into your waste beaker by accident? I'm at a part where you're doing your final clean and the thought occurred to me how it would really suck after all that effort. LOL it's giving me agita.
You should go on Reddit’s bullion feed and tell them you’re selling gold bullion because you’re a RU-vidr your bullion might hold a price standard for people later on in life as I think you’re RU-vid’s best refiner
I am guessing you cemented out the silver to enquart with the gold. I wouldn't mind seeing a video on the metals table. I wonder why copper came through with the silver?
It'll get run through the silver cell and come out pure silver. That could be used, but would kind of be a waste, since once used that way it would have to be put through the same process again. Sterling silver scrap is easy to get and works fine for that.
How much does the weight of the refining fluid change after you precipitate out the gold and the silver? I watch these videos and wonder if there is a noticeable change in weight as you do each step.
Yes there is. I performed an experiment to compare gold solution to same volume of plain water. Search “Wohlwill Process” on my channel and I do the experiment in that two-part video series.
I just had an idea, with the copper contaminated silver "puck" could you put it into solution and intentionally turn the silver into silver chloride to separate it from the copper? Making copper in solution, and silver chloride in the filter? You would then have to do... something to turn it back into silver metal (I would have to look up what the process was my recall is just not that good).
What happens to the excess sodium metabisulfite if you put in more than necessary to precipitate gold? Does it get dissolved into the remaining liquids?
Hey Sreetips, I don't remember which video you linked the info for your bulk buyer in Dallas. I want to say that it was one of the $47k gold bar series from 2020 but Couldn't find the info. Would you mind if I could get that info from you? I have a friend and myself who are going to start a recovery and refining outfit.
Question. Is it possible to recover Au from a colloidal solution that has been synthesized using a citrate reductant? Gold nanoparticle size approx 30nm in solution.
