Salt Bath Gold Refining

I'm using the AP process. After removing gold foils, I pulverize the material, add HCL, and drip (high-concentration) H2O2 over time to oxidize the remaining metals. When the reaction stops, I add a bit more of each and let it sit for 24 hours. After filtering, I …

Hello people i seen on U-tube about using Vinegar and salt to remove the gold foils off off the gold fingers of motherboards and i have about 10 pounds of them i scraped myself ! ... chandelier Bath Filler Mixer Taps with 1.5m Handheld Shower,Widespread Bathtub Tap Handle 4 ... for Melting Casting Refining Gold Silver Copper Aluminum Brass ...

Refining gold requires several steps. Refineries use chemical reactions and heat to remove the impurities and increase the overall fineness of the gold. Refineries may employ one or more of these steps, depending on …

Vinegar is not recommended as it creates a lot of waste. But since it is at it is. Add water and dissolve the crystals. Filter it and then either keep the foils as is for further refining …

-When vessel reaches room temp (25 °C) put the vessel in the freezer or on a salt water ice bath-Let stand until temperature of mixture reaches -5 °C-Let stand at -5 °C until all precipitate settles-Pour the COLD solution off into glass container with tightly sealed lid DO NOT POUR OFF ANY OF THE SALT IN THE BOTTOM!!!-Makes ~160 mL ~50% HNO3

It would also mean my PT salt will have some amount of ZR contamination requiring further purification. Assuming I am right about the ZR the next question is how to further refine my PT. Calcine and HCL bath(s)? I've read about using ammonia to dissolve the salt and form base metal hydroxides that can be filtered.

Unless the bottles have been opened and gold salts have been added to them for some strange reason (unlikely), I'm positive the 2 "B" units on the left contain only the non-gold chemicals needed to replenish the bath - no gold. They likely contain potassium citrate, citric acid, potassium phosphate, or combinations of these.

I am interested in the method of gold recovery from electronic scrap using a salt solution and a high current DC source (both of which I have available). Can anyone tell me …

Good day, just finishing about 20oz silver refine. After numerous times doing the salt/ lye method, I tried the cementation process. Source material was sterling silver, not sure on yield or purity yet with cement method but seems like a …

Electrolytes seem to vary from a silver nitrate only solution to electrolytes with "some" free nitric acid. "A typical silver-refining acid bath would be 200 grams per liter of silver nitrate and 30 grams per liter of nitric acid (Recovery and Refining of Precious Metals, C.W. Ammen, 1984). What would be an appropriate level of nitric acid to use?

The refractory ore is a realistic sample at 50ppm. Said another way it is .005% gold or 50 grams per ton. Try this test, make yourself a super ore that is 1% gold (that is 5,000 grams per ton or 5,000ppm). Take your 1 gram bead of gold and add 14 grams of copper clippings and 85 grams of black sands.

Gold chloride is formed when aqua regia digests gold scrap. Gold chloride has photochemical properties similar to the properties of the silver salts used in photography. Very minute …

The primary way that we test gold is with a nitric acid bath. Gold does not react with nitric acid but some gold alloys do react. By knowing what chemical reactions to look for when testing the gold we are able to visually determine the karat alloy of most items. The way we …

Most of the precious metal salts stay in soulution (unless you add a halogen like chlorine, which reacts with silver to form a solid metal salt). It is the lot of a refiner to know …

I plan on starting to purchase karat jewellery to supplement my income from processing computer scrap. I understand that we must inquart (melt)the karat jewellery with silver so the gold content is less than 25% of weight. Then dissolve base metals in 50/50 dilute nitric acid. 1st question -...

Recovery and refining is a complicated science and art, which can be confusing to someone just beginning, we discuss many processes and different metals, the information this forum contains is also overwhelming, and seems could take a lifetime to absorb it all, most things are discussed over and over, adding to the text and amount of ...

I was getting ready to get my hands on some HCl, nitric acid (or bleach), H2O2, stannous choride, SMB and pH testing paper for recovery. However, I recently discovered a far simpler and cheaper (albeit lengthier) way to seperate gold using a salt and vinegar solution. My questions are: 1. Which metals can be dissolved by a salt and vinegar ...

The first step is to dissolve the dirty Pd salt in NH4OH. When the NH4OH is first added the Pd salt will turn to a orange flesh colored salt. As more ammonium hydroxide is added with stirring the flesh colored salt will dissolve into a nearly clear yellow tinted solution. Some solids may remain behind.

If it's brownish that can mean low levels of iridium, or higher amounts of rhodium. If it's orange red, that means you've got too much chlorine in solution and Pd is co-precipitating.

Gold Recovery Correctly: I will detail a SAFE process of turning old electronic parts into little round lumps of pure gold. There are many tutorials that claim to offer methods of gold …

Chlorine and HCl acid (hydrochloric acid) are both of the halogen family, but they are very different in how they will react with metals. Chlorine can oxidize metals, even metals below hydrogen in the reactivity series (although it normally requires heat to help in this process), it will react with copper, and it will even react with gold to take electrons from gold.

The purpose of this thread is to begin to consolidate the vast amount of questions and answers related to the Acid Peroxide (aka AP) recovery process. First and foremost, the name for the process, Acid Peroxide is a misnomer as the active ingredient is actually copper II chloride (CuCl2), so it...

I've gotten a fair amount of gold precipitate, and I believe I know how to process it out and refine the gold. But I'm a little shaky on the other metals. Silver: precipitate from AP …

Doing an epsom salt bath is very simple. You will need to pour one gallon of water from your fish tank into a bucket, make sure you are using tank water! To that one gallon of tank water, add 1 tablespoon of epsom salt and mix it thoroughly until it completely dissolves. After you have it dissolved simply pick up your fish out of your tank and ...
