Filter through a tight filter, or wash into a porcelain spoon dry, or extract most of the liquid with a small piece of tissue paper, then dry, anneal then scope it... then show me.... if it's gold it will be Crystalline.Hi I'm going to do an unconventional stunt this time.
I'll post a PDF document since it have pictures and text together and I felt it would behave better in a PDF.
Anyways I hope someone has some views and information regarding the content in the PDF.

Deano.
Thanks for a beautiful thread.
We have been trying the Hypochlorite leach, since we have no experience with it,
we don't know if there will be color change or anything like that when the leach pick up gold.
I don't even know a small thing like if it will evolve bubbles during leach.
We do suspect it has leached some, but the results are inconclusive.
Will stannous work, how about SMB, will that drop what is in the test leach?
Will Carbon or Resin be best for production leach?
We struggle and wonder if the salt may be the issue, we tried a electrolytic cell, but I guess the gold concentration may be too low.

Hi Per, I didnt realise you posted images of the spoon tests, anyway, attached are images of the the spoon test particles (reduced/precipitated by the stannous) as seen through the microscope at 100x, DF, no filters. Sorry for the late posting. The cubic crystals are salt from the hypo leach. Testing is still on going as you knowSince we are new to this and the ore is somewhat refractory/Special we are doing a lot of trials.
This is what we have notice so far:
Stannous do not work as expected as per information. It gives a precipitate in stead of colloidal color change.
There are no color change.
Stannous tests show less return after long time 7 hours seem half of two hours.
All this is per information, so we will proceed to carbon column in circuit.
Is it best to let the leach finish and then pump it throuhgh, or constant pumping?

To begin with, I couldn't agree more with this but I found this out on a local online portal here like Amazon (although not as big). Although the seller is Chinese but little would we think of its authenticity when it comes to being openly laid out onto the portal for purchase. It doesn't have any previous sales and also, it isn't very expensive. On the other hand I can also procure a platinized titanium anode that too very cheap and that is something that enhances my suspicion too since platinum plated wouldn't be as cheap as it is shown.marketing slant for whichever market the sellers were targeting.
Like you have pointed out, this then probably needs some sort of internship under experienced guidance in order to get an acquainted understanding of the visual-adsorption of the gold itself?It is easy to do testing to find out the level of gold adsorption
Although I'm not anywhere near it now, but I think it would be best suited to be better prepared for IF there are any future plans for pursuing it. The more the study the better preparations right? so I'll consider understanding the use and mechanics of an AA indefinitely. For now if it is highly suggested for this operation, then ill drop this course of action and learn more about it.If you are serious about doing larger scale gold recycling then an AA is virtually a necessity as you can instantly see what gold levels are in your liquors and you can then adjust your chemical inputs to suit.
I'll surely go by this rule even if I go for it at a later time.For most gold work you are looking at a "bare bones" model AA, you do not need all of the options beloved by the designers of these units.
Speaking of the IC chips in lieu of the aforementioned, they contain microscopic gold bonding wires if not atomic and they're well packed inside the ceramic epoxy carbon casing etc. As I mentioned earlier that the carbon needs be roasted at a higher temperature to become inert in nature. So the case in question : If we roast the carbon, we risk losing gold to volatilization. If we don't, we risk it being adsorbed onto the carbon. In my humble seek for knowledge sir, what would be your suggestion in this case then?Gold volatilising is really dependent on the surface area of the gold you are heating.
If you have the gold present at near atomic size particles it will volatilise at much lower temperatures than quoted in the literature.
My suspicion is that the volatilisation of gold chlorides mainly gets prominence due to the high surface area of such chlorides especially when disintegration of the chloride complex occurs at temperature.
