I had try tihs , But not pass !
SO
2 + Ag(NO
3 )
2 + Cr
2 O
3 + Au*FeO*Cr
2 O
3 + H
2 O= AuO + AgO
2 + NO + Cr
2 (NO
3 )
3 + H
2 + FeO*Cr
2 *SO
2
Try to product to metal only the other go natual .

The error is what should this reaction be.
1. Either Educts and products have wrong formulas.
It is AgNO3 , Au2 O or Au2 O3 , Ag2 O, Cr(NO3 )3 , hydrogen will not be developed. And what should be Au*FeO*Cr2 O3 and FeO *Cr2 *SO2 .

chromium(III) oxide (Cr2 O3 ) used to coating spoon
and FeO*Cr2 O3 is refer to soil that add to Au atom .

Base On Probality Theory :
S + 2Ag(NO3 )2 + 4Cr2 O3 + Au*FeO*Cr2 O3 + 2H2 O + 3O2 = Au*Ag*Fe*(Cr2 O3 )4 + 2NO2 + SO2 + H2 Au*Ag*Fe*Cr2 O3
TA = 0-10 C and Use Heat Energy !
* Balance system on this website ont support , I'm imply by own.

Please describe what you want to do. Your equations make no sense.

Last term of my equation could be omit . (in whirl pool system)
This is adiabatic process: exothermic reaction, should make this lab on open air room , require N form air to form NO, NO2
So Au has 1 atom two side of balance equation.

You didn't answer my question. What is your key target. You want to remove gold from an ore? Your Ore is FeO*Cr2 O3 *Au?
If this is the case I would use HCl.

HCl can make reaction with iron, Fe but usually not for Cr2 O3 like stainless still spoon from wikipedia refer Cr2 O3 , too.
Yes, I want to extract the gold from ore material Si , K , ... Also
But balance program not work with propability theory , or not ?

OK I got
3 S + 2 Ag(NO
3 )
2 + 6 Cr
2 O
3 + 2 Au*FeO*Cr
2 O
3 = 2 Au*Ag*Fe*(Cr
2 O
3 )
4 + 4 NO
2 + 3 SO
2
Except : H
2 O , O
2 for book in university , tecnicial student
But in real situation both are various on temporation. Hazard !!!

I beg you for chemical equation using HCl to got Au .
Sir, Thank You .

Getting Au from what. Normally Au existing as element already. You have to clean it from the other stuff. normaly used Cyanide or mercury, very Poisson procedure. HCl cannot dissolve Au. But its able to dissolve other metals and their oxides.

I found the balance equation on program on this website:
AuO2 + 2HCl = 2AuClO2 + H2

First there is no AuO2 . Gold has max 3+ in oxidation number.
And hydrogen can also not developed.
And please dont write these nonse equations in future.
There is no balance and also no right components either right reactions.

No nonsence ! Sir.
These Process :
AuO2 + 2HCl = AuCl2 + H2 + O2
AuCl2 + H2 O = AuO + H2 + Cl2
2AuO = 2Au + O2
is sample extraction of natural ore , 2 mole of HCl can interactive to AuO2 by the first . And so on.

Zour therorey doesnt work because you think to have AuO2 . But this component is not existing on this planet, probably not in this universe.
Gold max oxidation number is +, what means Au2 O3 and this is very unstable.
