Does Gold dissolve in mix of NaNO3 and NaOH?
I think PGM's like Ir, Os... are dissolved like this.
Should it be melted, or can be done in water?
I've heard that people "think" that Au(OH)3 dissolves in bases forming "probably" soluble aurate. Nitrate acts as oxidant, and base as dissolver (just
like for Al)...
Can Sodium Peroxide or Superoxide (both easy to make, just heat oxide or carbonate or hydroxide) be used instead of nitrate?
I prefer to use bases instead of acids! And also don't want cyanides. Because bases dissolve more elements than acids forming for example (with oxides
or hydroxides) soluble salts (e.g. Germanate, Silicate, Aurate, Zirconate, Hafnate...). Also I would use bases for getting elements from rocks or
soil, because acid's can*t do anythiing (silica blocks reaching other chemicals like Na, K, Ca, Mg, Fe, Al...).

Fibre ─ probably faster than yours, damn yer eyes . . . ?
And I never time myself, much rather plucking random numbers from the æther!

Nitrate isn't a very good oxidizer in basic solution.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

Alright, let me rephrase that to "basic aqueous solutions".
Please remember: "Filtrate" is not a verb.
