I find it fascinating how entertaining this is when you would think it would be so boring. I firmly believe most of that comes from how complete Sreetips is not only in his demonstrations but, most importantly, in his explanations. You could take the contents of his library here on KZbin and start this up yourself. Glassware to fume hoods is right here.

[@golder70]

Great part 1&2! The cloudiness comes from AgCl which is soluble in concentrated HCl when pH is very low and the higher the better the solubility of AgCl... when rinsing the filter with distilled water the pH rises and the AgCl comes out of solution. Those microscopic cristalsl of AgCl serve as cristallisation core for the gold when dropping it. You have to either concentrate the gold solution by evaporating most of the remaining HCl and then dilute with water and all the AgCl comes out, then filter and drop the Gold OR you boil the dropped Gold in concentrated HCl several times. But this is not so efficient because inside the gold powder units there is an AgCl core which is liberated when you redissolve the gold... Exolained this in extenso in some of my vids.

[@sreetips]

You’ve explained this before. I can see it now. Thank you

[@roberthayward9299]

Thanks for another great, honest video. I have a couple of comments but first my qualifications. I taught chemistry for more than 30 years. The cloudy precipitate is very likely silver chloride IMO. You skipped the inquartation/nitric dissolution step that would have removed the silver for later recovery. The passivated metal you discovered after your first aqua regia dissolution adds further evidence to the silver chloride hypothesis. Easy to be wise after the event of course. Couldn't be sure but the little "tail" at the end of your ingot evidences that some contamination remains in your gold. I see lots of comments regarding recovery of value from your cemented copper. Probably wouldn't be cost effective unless there are some precious metals retained in this copper but an electrolytic refining step for copper might be worth considering. Thanks again for your videos. I really enjoy them.

[@gnomespace]

Love the come-back part! Old prof used to make us put a section at the end of our projects (there is a name for it that escapes me) that was specific on what went wrong. His opinion, and I totally agree, is that errors are where half of learning takes place. Books are ouststanding base sources of what others have found, but when you screw something up and can figure out how and why you pump up you own knowledge base and gain confidence to step further out. Or something like that.

I watched both from the beginning and when you calculated the 2.5% in, I kept hoping for more. I saw there was a lot of silver in so I got some of my hope up but the weigh-in at the end made this worthwhile, 2700 is better than 2000 dollars, especially with all that work.

How is it that at about 5:00 you can filter the Aqua Regia solution through paper? I would have assumed it would eat the filter paper.

[@sreetips]

The filters hold up well with cold aqua regia solution. A hot solution is not the same. Even a hot silver nitrate solution can cause a filter paper to fail. That’s why I have a vacuum switch on my system to shut off the vacuum pump at about 7 inches. Sulfuric acid, forget about it. Hot or cold, the paper filters won’t hold up. That’s why I use microfiber glass filters to filter sulfuric acid solutions.

I love your videos and am at the very begginer of jewelry manufacturing and refining. I found in my search that if youa don't want to pay outrageous for your gold inventory it's best to try and find the the carated gold and gold filled scrap. I get where to find gold filled items but where do you find the gold carat for refining and resell. Any info would be greatly appreciated. I have 1500 grams of gold filled so far and all the real carat gold I found even scrap is way over charged on ebay and the other selling sites. Any help would be very useful.

[@sreetips]

Yard sales, thrift store, resale shops, consignment stores, flea markets, estate sales. Got to get up early and be there first or the gold will be gone. People on eBay know what they have and want top dollar - eBay is not a good place to buy gold. You can’t sit on your computer, in your pajamas, and expect to buy gold online at a discount. However, you can find it at deep discounts at the aforementioned places if you know when, where and what to look for. Most people believe, incorrectly, that paper dollars are more valuable than gold. We can use this misconception to buy gold at a discount. But it’s not going to fall in your lap. You must hunt. Good luck.

[@arcare001]

So when the copper cements out on the iron, is it replacing the iron or does the iron stay the same, still an angle iron and relatively the same amount of iron? And if it just plates out on the iron, after the entire surface of the angle iron is covered with copper, does the cementation stop?

[@sreetips]

Please see “reactivity series of metals” the copper “cements” out on the iron as the iron goes into solution. The two metals trade places. Once the reaction is done, I’ll have metallic copper in an acidic iron solution.

[@scott2296]

It looks like you were battling silver or lead, or both. Your filtered solution would turn cloudy from the water you had used to wet the filter papers prior to filtering and the water used to rise the papers afterwards. Not that it needs to be identified but if whether or not the white contaminant turns purple in sunlight, this could prove useful under certain circumstances. Next time, instead of repeatedly filtering, start over again by getting all the solution back into a single vessel, add hydrochloric to drop any silver, add sulfuric to drop any lead, let sit for a half hour or so, preferably chilled, then do the filtering. No need to be shy with the hydrochloric and sulfuric in this situation, won't hurt a thing, so be generous. It looked as if you were using distilled during the filtering process, if you had been using tap it would have dropped even more of the contaminant out of solution.
