Inquarting With GOLD FILLED Instead of Silver

[@williamfoote2888]

-That white gold in your 14k portion is Rh plated. -You could use the Au electroplated material to inquart. The Au is plated on brass, which is Ni and then Au electroplated. Just assume that all the electroplated weight is 'inquart.' You'd be adding in the same Cu and Zn that's part of your Au filled material. -That junk metal is 'brass' or 'Zn diecast', that is zincate immersion (Na2ZnO3) coated, Cu flashed, Cu plated, Ni flashed, then Au flashed. Zn is just as useful to inquart as Cu or Ag. It all comes out when you do your HNO3 boils. -The material at the bottom of your melt dish is likely stainless steel. -I'm surprised at how little slag you have floating on top. That'd be your Zn or maybe Pb oxides. Looks like they might have been rinsed out into the drain when you spatter cast your melt into the cooling water tank. -The activity series isn't going to predict reactivity with acid. If anything, the reaction you got would be from the amount of Cu and Zn in the inquarted gold. Whatever Zn you add to your process will pas all the way through to your final Fe waste stream and be discharged in any liquid supernate. -Jeez. I didn't even consider Sn. -That white sediment on the bottom of the beaker, after the HCl boil, is your PbSO4. -Double, triple or even quadruple up on your filter paper for the Buchner funnel. In the old days, we'd use an asbestos fiber filter mat. I'd think you could use an activated carbon layer on top of the filter papers to help you get your clear solution. Of course, you'd need to add the carbon to your filter paper stash for later metal recovery. Yes, the filtration step will be slow, but less sensitive to high pressure vacuum. That IS nice Au! Long road to well done!

[@lazerwolfdiecast]

It would be cool to see a video explaining the cost to profit ratio. Like how much you spend on chemicals, electricity, and metals compared to the value of the finished product.

[@anthonyrstrawbridge]

I believe it is negative. The scrap metal cost is fixed at scrap value. The refining costs are expensive. If you add up the two costs it is a big loss. Also, a percentage of the scrap material is lost during refining. The gold value in dollars per weight is the same regardless of purity. I don't think the cost in dollars is his mission. The silver from karat scrap is very profitable IMHO. 👍 The costs of equipment repairs, replacements, and upgrades and now replacements again, has been significant.

[@guygordon2780]

Not only is the Zinc more reactive, but as it is removed early, it's absence will leave channels through the remaining mostly copper alloy. Those channels will add a lot of surface area, thus speeding up the remainder of the extraction. You might find yourself using this more often, to save time. Lets hope it doesn't add any problems. Of course, you could also inquart using a mixture of sterling silver and gold filled scrap.

[@DFPercush]

Might be worth experimenting to see at what percent of zinc does the gold start to fall apart and form suspensions.

[@johnson2207]

Using silver feeds the silver cell.

[@lazyman114]

I think he spent maybe up to 10 hours extra to recover 6 extra grams from the gold filled scrap. Combined with the extra headache, I think it's not worth using this method.

[@guygordon2780]

​@@lazyman114 Trying something new always takes more time. Doesn't mean it's not worth trying. Best way to learn something new. The problem Steetips ran into is not inherent to this method. It's a problem whenever the inquarted gold is much less than 25%. At 25% you get a gold sponge.

[@Sanzus2]

Ended up with a good looking bar! First drop the liquid was the same color skin turns when wearing gold filled jewelry! Have you thought about going to a greater gold percentage with the alloy to see if it prevents it from going colloidal?

[@sreetips]

Didn’t think of it for this run. But it’s not a bad idea.

[@Sanzus2]

@@sreetips the other thought would be to re-melt after the first couple of nitric acid baths when you are no longer getting a reaction and most of the zinc is gone. You would be left with mostly copper and some silver and it might keep it from breaking down into colloidal.

[@1911darkstar]

Beautiful bar! Super interesting process this time. It looked like you were loosing quite a bit when the gold was in that finely divided state during the pouring off process. It’s really interesting the different states the gold goes through during the process. Any ideas for future inquarting, i.e different metals or just going to stick with sterling?

I have more sterling that needs to be dissolved so I’ll probably use that.

[@roberthayward9299]

Great work as usual Sreetips. The zinc and copper will use a little more nitric acid than the silver would have because these metals both have a valence of 2 rather than the valence of 1 for silver. Interestingly, under some controlled reaction conditions, zinc will form nitrous oxide "laughing gas" instead of the brown nitrogen dioxide that usually forms.

[@vinnycordeiro]

Considering that a lot of colloidal gold went to your temporary waste container while cleaning the precipitated gold, the yield was really good. I believe it was so close to the theoretical yield because of the extra from the gold filled material, about 5 to 6 grams. Anyway, that's a messy alternative to be used when you have no silver/copper readily available, but it is surely not ideal.

[@daftwulli6145]

well sure it is messier, BUT on the other hand you do 2 refinings in one, scrap and carat, so it seems like it does save work, and quite a bit

[@kwinterburn]

Don't know whether this might be useful but I used to have to extract settled sediments from the liquids, the problem was you couldn't Syphon off all of the liquid, so I got a wine bottle with a plastic screw top, cut off the bottom with a tile saw, then you could fill with the liquid and leave it, the sediments settled on the plastic cap right in the neck, so you could Syphon off almost all the liquid without disturbing the sediment, it's also how the painters extract pigment from water based paint out of brushes, it just flows out of the brush and falls to the bottom without circulation,

When you get the purple gold nanoparticles in suspension, I wonder if adding a small amount of SMB would act as a surfactant, and cause them to condense? I know that it can make particles of many atoms when it reacts with chloroauric, but I wonder if it can have the same effect on particles in suspension. Next time you get some 'purple gold' it might be worth putting some in your spot wells and trying different remedies like copperous, or even lye. If you can find an additive that efficiently condenses colloidal gold, it might open up other refining options.

Kindest regards from sweden so excuse the bad english

Considering the amount lost in waste that was a excellent total. Way more than I thought.

I know a lot of pieces not plumb would always be either under or over karat stamp. Would that interfere in inquarting ?

[@sreetips]

There’s a “Goldie locks” range for inquarting. Too much silver and the gold will crumble to a powder making separation of the silver difficult to pour off. Too little silver and the nitric may not be able to penetrate.

[@radekc5325]

I have this question: when you have gold dissolved in aqua regia, and you drop it out with SMB, do all metals drop out? Or are there any metal contaminants (like, say, copper) that would stay in solution, if they were present? Obviously sodium stays in liquid since it's part of SMB, so I guess it would be an example that answers my question, but I do wonder if there are other, more relevant, metals, that are left behind by this step.

[@nothanks1877]

If you do water boils after the initial nitric boils you should dissolve out and remove 99.999% of the base metal nitrates prior to the aqua Regia. The filter then removes most of the sulfates that were insoluble in both water and aqua Regia. Ideally that means very little is in the solution your adding the SMB too. It should in theory at that point be functionally pure chloroauric acid in water. The cloudiness of the first crash are the nanoparticles left over that pass the filter. So you do the second aqua Regia dissolve to give yourself another filtration chance to get them out. Each time should be 99.5%+ removal of contaminates so two is normally enough for three 9 gold. Three often gets you close to four 9 gold. Rarely worth bothering for more than four 9 gold.

[@sreetips]

SMB is fairly selective in that it will precipitate only the gold and leave the copper in solution. HOWEVER, it will precipitate out platinum group metals, in trace amounts, if they are present in the gold solution. Ferrous sulfate seems to be the most selective of all gold precipitants. It (ferrous sulfate) “will drop the gold, all the gold, and nothing but the gold.”
