Pregnant solution of cyanide


#1

I was playing around in the lab with my dentist friend when he got
out a bottle of pregnant solution of cyanide. We proceeded to plate
and remove gold from a silver coin using a small 9v battery. I have
always wanted to do a little gold plating on some of my silver pieces.
I was able to get some briquettes of cyanide from a gold mine that
was using a heap-leach process. The briquettes are about the size of
charcoal briquettes used for bar-B-Q but are white. I’m not sure if
they are sodium cyanide or potassium cyanide. Does anybody out there
have info on how to make a pregnant solution. Do I just dissolve a
briquette in distilled h2o and then throw in a 24k gold eagle or 22k
Krugerrand? Will the 22k solution plate 22k? Can I use a small
transformer to plate rather than a battery? Just how dangerous will
this be? I really don’t want to die just yet.

G’day; My goodness I wonder a) who could be so brave/foolish to get
some cyanide in the family way, b) I wait with bated breath to learn
what the offspring might look like, (cyanates, thiocyanates…?) and
c) what do you really mean by 'pregnant?

 I'm not sure if they are sodium cyanide or potassium cyanide. 

The briquettes are almost certainly sodium cyanide as the sodium salt
is far cheaper than the potassium salt, is very comparable in
properties, and is always used by the mining industry/refiners.

I really can’t imagine anyone doing it the old fashioned way - an in
vitro method perhaps?

    Do I just dissolve a briquette in distilled h2o and then throw
in a 24k gold eagle or 22k Krugerrand? Will the 22k solution plate
22k? Can I use a small transformer to plate rather than a battery?

If one connects a positive wire to the gold and the negative wire to
the object to be plated, and in a solution of pot or sodium cyanide
yes, you will get plate; an electric current is essential. Yes, you
can use a transformer - but ONLY if a rectifier is used to convert the
AC current into DC. An AC current will simply shunt the gold back and
forth at around 60 times per second and nothing much will happen.

I would strongly suggest that you get some books from the library and
read up about plating. I came to the conclusion long ago that good
plating is as much an art as a science. Furthermore, a good, bright
adherent plate requires a good deal of preparation of the object
before anything else is done. Anything else will be a waste of time
and of gold.

Be VERY careful with the cyanide; it is very caustic and corrosive.
Wear goggles and rubber gloves if handling it. Never allow any acid to
get anywhere near it. Keep it in a well closed container as it
rapidly absorbs carbon dioxide to produce sodium carbonate. And have
it conspicuously labelled and kept in a place where children can’t get
at it. – Cheers now,

I would guess that your briquette could be very dangerous.
