I think a complete thread on fulminates would be a good ldea, various fulminates have indeed been discussed, but I think we need a dedicated thread,
what do you think?

I'm sorry I haven't read this thread before!
This guy has many pages with all you want to know (and many detailed things you didnt want to know) about amateur gold extraction. This is his page
about cyanide:
http://webpages.charter.net/kwilliams00/bcftp/docs/cyanide.htm
Its difficult to browse the pages because it doesnt seem to have an index. Try this:
http://webpages.charter.net/kwilliams00/bcftp/docs/
Good luck!

Yes, cyanic acid is a synonym for fulminic acid, that looks like an interesting way to mercury fulminate for the HNO3 impoverished, make or aqquire
the HgCN and add H2O2 |
No, fulminates and cyanates are isomeric, but not the same.

Which method is less dangerous - extracting the gold with mercury (having in mind the potential risk of mercury fumes when distilling), or extracting
using some cyanide salt (having in mind the toxicity of cyanide compounds)?
I have access to few hundreds kilograms of gold ore, so i guess extracting with mercury would be a huge waste of time, so i think ill rather just try
to find some NaCN (although, it is much harder to find NaCN than mercury here)
Does anyone know a relatively safe NaCN synthesis?

Would a solution of NaNO<sub>3</sub> and hydrochloric acid also work? Solid nitrates are a helluva lot easier to come across then cyanides
are (not to mention a helluva lot safer to work with).
In that case you could crush the rock to a powder and add the powder to the solution of NaNO<sub>3</sub> in HCl(dil/conc). I presume you
can comfortably wait for a week?

A mixture of bromide and bromate salts will dissolve gold.

What about HCl reacting with other compounds that form the ore, creating salts that could also dissolve in the solution and thereby affect the
extraction?

Can you provide more information about this type of extraction?

The acid will most probably react with the carbonates in the ore, the silicates will not really be affected by it. I believe gold ore is mostly quartz
and carbonates so there will not be a lot of unexpected reactions like H<sub>2</sub>S formation etc.
