Recovery of All Metals from Aqua Regia (non-selective recovery)

[@flakybiskets5796]

so you can precipitate out the gold by itself first? and then get the rest of the metals out or is the precipitate all the metals and you can do over again?

[@user-lk8fi6fk3f]

I've heard of a method of dissolving gold in Glycine. It would be interesting to make a video on how to extract gold from Glycine.

[@blaniardmarshall8924]

Sorry, no idea.

your informations are very impressive!

Does this device deposit gold with other things if I have an error in gold precipitation

2:00 an anode bag how is attached to the cathode terminal ??? an anode bag will be on the anode termianl

[@mohammadusmani5351]

Cathode would be titanium and anode would be graphite right?

Very nice 👍👍👍

[@osirismunoz5730]

Excellent video but I don't understand what the cathode is and what the anode is and how to get it out of the way.

[@shorinternational3841]

Not exactly sure what your misunderstanding is or what you want to get out of the way? Both are necessary in your solution during electrodeposition - watch again carefully from 1:28 onwards. Graphite, silver or titanium plates or rods may be used as your cathode AND anode. Wire one to the negative/red pole of your rectifier, that becomes your anode, and the other to the positive/black pole of your rectifier. That becomes the cathode upon which metal deposits during electrodeposition.

[@osirismunoz5730]

Hello, good evening. I would like to learn and recover all the metals from the aqua regia. If they have a course or some cost, you let me know.

How to seprate gold from iron powder

[@mehrasa-tq1vh]

hi A spoonful of trisodium phosphate is used for several liters of acid? Can both anode and cathode be used from the same metal? Or is one metal and the other graphite? Or both graphite? Thank you very much for your educational video

[@shorinternational3841]

You can add as much or as little TSP as you choose. The anode and cathode can be of the same or different materials of your choosing. However, if you use a metal for the anode, make sure you don't use a metal that will dissolve in your solution. Regarding your second question- Black would be typical, so don't be concerned with the color. This precipitate should be refined with aqua regia. For that procedure, see the embedded video on the following page www.ishor.com/aqua-regia-gold-refining-starter-supplies

I have one more question I have a solution that contains gold, palladium and copper metals. I used aluminum to get some sediment, but the aluminum in the powder is black. I washed the powder several times to remove the acid. Then how should I separate the metals? Can you guide me?

How get gold from solution by electrolysis instead of gold plate?

[@blaniardmarshall8924]

Gold plating and electrolysis are the same thing. Please note, this procedure does not recover gold selectively. All metals will be removed from solution. For selective precipitation, see our refining videos.

[@abbottcostello2446]

im a beginner and cant simply dissolve my gold why is that ive used everything and even a diluted nitric acid mixed with hcl 2-300 ml of hcl then slowly adding diluted nitric acid but still no gold in solution?

[@blaniardmarshall8924]

First, watch the following video- kzbin.info/www/bejne/qmHPhYijpLh2g8U. This will provide you with comprehensive instructions for aqua regia refining. The answer is likely to be found in the video. But if not, just ask again.

[@kiyanliyan2931]

Hello What kind of metal is the anode in this process? Titanium or graphite?

[@blaniardmarshall8924]

Whichever is either most convenient or cheaper for you. Both work well.

[@HIB1968]

Hi do you need to adjust the Ph before you start the plating out? And does it plate all the PM metals and base metals? Thanks Hib

[@blaniardmarshall8924]

Adding baking soda until it no longer causes foaming will make your solution pH neutral. All metals will plate out of solution.

I have 10 liters of concentrated Rhodium plating solution, how should i recover it before sending it to wastewater treatment?

[@blaniardmarshall8924]

If the solution is considered spent because it no longer plates rhodium, the rhodium left in solution is not worth recovering. However, if the rhodium solution is considered spent because it is no longer plating bright, well that is another story. In that case, you can clean the solution by filtering through activated charcoal. This will clean the impurities out of the solution but it will also absorb some of the rhodium, so not a good idea to utilize except when you have to.

[@lesliechea7136]

@@blaniardmarshall8924 Would it be best if I use zinc to confirm the content?

[@blaniardmarshall8924]

@@lesliechea7136 Since not all the zinc will dissolve and the solids left behind will be more zinc than rhodium, that is unlikely to provide useful information for you. Electrolytic recovery is likely to provide you with the best result. However, as previously stated, if the rhodium is exhausted from the solution, this is likely to be wasted effort.

Hi I have gold,palladium and rhodium ore, I am making concentrate then doing aqua regia, I can extract only gold but pd and Rh remain in aqua regia or in crushed ores, please help me how to extract pd and Rh?? thanks a lot

[@blaniardmarshall8924]

To dissolve platinum group metals, you will need to heat the solution to around 80C. Even at those elevated temperatures, it will take much longer (at least 1-2 hours) to dissolve the pgm's. Once dissolved, paladium can be selectively precipitated with sodium chlorate (not sodium chloride). Rhodium can be precipitated with hydrazine.

[@misccomments9752]

Hydrazine is rocket fuel. Do not attempt without expert chemical lab pro guidance. Temperature and other limits must not be exceeded or explosion will result.

only somewhat wrong because Ti cannot be used as an anode it will pass 0 amps due to it being a valve metal.
