SSN - Which Salt?

[Gratilla]

There is currently an active parallel thread at:

http://goldrefiningforum.com/phpBB3/viewtopic.php?f=44&t=19174

discussing SSN from the aspect of raising ORP in order to increase the effectiveness of SSN. It is being suggested that adding Iodine (and/or maybe Bromine) may do just that ie increase the ORP.

Also, if you take a look at the Intec Gold Process here:

(which, IMO, is an enhanced/commercial version SSN), you'll see that they use mixed halides by adding "Iodine and/or Bromine" without explanation!?!

Could it be that they're increasing the effectiveness of their (SSN?) leach by increasing the ORP by adding Iodine/Bromine???

I'm taking a WILD guess here, Guys.

Pure NaCl can be purchased as canning or pickling salt.
Not knowing the exact composition,
I question the form of iodine in table salt as a source of free halide ions.
I would trust sea salt to have more free halides, by gut feeling,
but then the issues of other contaminants come into play.

Also, to find forum posts with 3 or 2 letter abbreviations
you can use the google custom search box at the top of the page.
I'd prefer the format of the results given in the built-in search box,
but the google route is a suitable work around.
