We used this recipe, there's large excess of zinc but it works:

Add 25 g of NaOH per liter
Add 12x the amount of dissolved gold in zinc dust. (1g of gold = 12g of zinc)
the zinc is added little by little with vigorous stirring.


When you master this, you should go to electrolysis.

Excuse me. I don't mean anything

No I can't
I don't have any experience in cyanide
Why you don't dissolve gold in aqua regia ? It is very safer than cyanide

He wants to precipitate gold from cyanide solution. Anybody can help him?

Where are you? How much money you pay for motherboard, graphic,ram,cpu and...?

I don't like acids

So i should go electrolysis now!
Thank you❤
Do you know how gold will be turn back in electrolysis?

Sorry but what do you do?

Hello

Firstly- not sure whether mixing sex with cyanide is a good idea.

Secondly you're looking at the maths incorrectly- the amount of active carbon that's required depends upon:

Gold loading in solution
Other metals loaded into solution.

It's not a per litre basis unless you've got an AAS reading telling you how much gold is there per litre, and even then it depends on the other metals too because the active carbon will take it all out. The total weight of metals will contribute to the loading of the carbon.

Does coconut water activated carbon can absorb gold , or it should be specialist for gold , because in my country only available carbon for water treatment with size 6x12

Hello
- I use jinchan to leach gold ore
- And i use activated carbon to adsorp the gold

I need to wash the carbon from the slurry after removing the carbon from the busket so i can calcine it to dissolve it in awua regia

How i wash the carbon without precipitate the gold from it ?

I think you are supposed to have the carbon in a tank/bag/holder inside a coarse filter cloth or similar and let clean filtered liquid slowly run through it until it can't take more gold.
Then put it in AR, Cyanide or what ever you prefer and leach it with.
You can then reuse it or ash it and leach again.
If you left it in a muddy dirty solution you will have massive losses, I believe, and the mud/slurry may clog the pores and reduce the effectiveness of the carbon.
But then again I'm not an expert.

 

[Deano]

If you wash the carbon with water which is not boiling you will not lose any gold complexes from activated carbon.
You need to have water heated to at least 90C to start to lose gold.
