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.

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.

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.

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.

I do enjoy your videos. My father would let me do some precious metal refining in the backyard. I mostly did silver scrap but did study and try some gold computer scrap. My setup was a few flasks and plastic buckets. He would come out and ask me what I was doing and then go back inside after I explained. You might try Refining Gold with Dibutyl Carbitol to separate the gold solution from persistent contamination. Oxalic acid as a final precipitation agent is supposed to yield high purity gold.
