The whole reason behind inquartation and parting is to reduce the gold content so that the AR can disolve the gold. If the silver content is too high, silver chloride will form on the outside preventing access to the gold by the AR. You could literally boil 20 Karat gold in AR for days with no joy. Too much silver and your gold ends up too fine ...

To be accurate after inquarting your gold scrap and dissolving your base metals and silver in nitric you will have contaminated gold powder and copper, silver and other base metal nitrate. To remove your silver you need to cement it out with copper which will leave you with silver and trace amounts of gold, copper and any PGMs in the solution.

6 - Melting of pure 24K gold. Now that our gold powder is clean and dry it's time to melt it into a button, pour ingot or even casting grains. Note: If a re-refining is desired, incinerate the powder (red hot) and repeat all steps from step 3 of this tutorial. A- Transfer gold powder to a watch glass or other vessel.

Metals, The 12kt gold bar is already 50% base metals, by adding of the weight in sterling silver in the melt the result is 6Kt gold alloy, or 3:1. Here's my math for a 50 gram bar of 12kt gold: 50 x 0.5 = 25 grams of pure gold and 25 grams of base metals plus silver. 50 grams of added sterling + 25 grams of base metals plus Ag in the scrap ...

Dec 22, 2010. #4. Maybe it is just me, but something seems odd here if you are asking these questions yet buying and having refined lots of 22K+ gold, 50+ kilos at a shot, at a profit. If you are serious, give some further details and we have members here that can help. I remain skeptical for the time being.

Inquarting is still the way to go if you are "toll refining" lot by lot and paying the customer on out turn, but if your lots grow and you decide to skip the individual lot processing for bulk refining, think tumblers. This type of tumbler is very effective, the larger one tumbles buckets from 5 to 12 gallons.

The second way is to add copper to bring Au content to less than 37% and treat the alloy first with Nitric Acid to remove silver plus all base metal impurities. Once done, recover gold which is practically more than 99.90 % pure, and go through the aquaregia process to recover all gold of fine quality.

It takes (about) 4 times more nitric acid (67 - 70 %) to dissolve a gram of copper compared to dissolving a gram of silver. It takes (about) 1 ml nitric to dissolve a gram of silver - so (about) 4 ml of nitric to dissolve a gram of copper. So your cost for the acid goes up 4 times for every gram of copper you add to do your inquarting.

The Platinum is 4.9%, again for a small lot. This is all head math so I should check it. Anyway over $700 per week is a lot to give up. Depending on what you spend on nitric acid, which may be a lot if you pay what small users in the USA pay, you should be able to save some serious money refining in house.

Interesting. Great idea. I think it could easily be done, at least for yellow, green, and red alloys, which contain only gold, silver, copper, and a little zinc. White gold, with it's nickel or palladium, may cause a problem. After silver inquarting, on an average of 50% gold - ballpark numbers: Au = 25%, Cu = 20%, and Ag = 55%.

2 Subtract 6 from that number, the number 6 is always a constant. 3 The result of that subtraction is multiplied by the weight of your gold to be quartered. 4 The result of that multiplication is divided by 6. 441.85 are the grams of silver or copper you need to add to bring that 14k gold to 6k gold.

It is known gold and aluminium do alloy, it makes purple gold, beautiful yet crumbly and pretty much useless for jewelry.

Dec 31, 2009. #2. The term inquarting comes from the ancients meaning to make into quarters. So make the gold content at least 1 quarter and you'll be OK. If you don't know the gold content assume it is all gold and add 3 times its weight in silver. You can't add too much silver but if you don't add enough it won't dissolve in nitric either.

With inquarting you bring the gold below 6 karat(25% gold 75% silver) so nitric acid can digest all the silver from the gold. This is not as simple as i just explained and you need to prepare for all the steps. A good you tuber to watch is sreetips. He has some good video's about inquarting gold.

spaceships said: Adding copper would increase the amount of Nitric required over that of adding silver. I would suggest silver over copper any day. My limited understanding of inquarting ( Harold is the best on here for that) suggests that you need the gold content to be at the highest 25% or under 25% overall.

Here's what you should do. 1, Filter the solution and dissolve the remaining solids in ammonium hydroxide. This will dissolve the silver chloride. 2, The clean gold solids should be weighed, and inquarted in silver. 3, The silver / gold alloy should be parted in 50% nitric acid (half nitric half distilled water.)
