Guys I need help.

[TransitionM]

Been listening activity for last year and a half. Have read Hoke book mentioned , along with other threads and literature and I have started refining (refining ore). Definitely know I have Pd; also believe residual material contains Rh, Ir, Os, Ru (aqua regia...). My problem is I didn't prepare for the silver, that I should have prepared for and I want to find the best way to separated at this point.

are you sure you do not have arsenic in your ore? be careful and only work in highly ventillated areas.

it's hard to tell what's going on in your photo, but the chlorine in the HCl of the AR should turn the silver into silver chloride. i'm guessing this is the white foam in your pictures. but it looks really dry... or is this just your ore?

As the Master says, it is hard to tell what you have going on. Some pics of your ore ( pre crushed ), and a rough idea of where it came from will do wonders. If you XRFed the ore and got high readings of PGMs, read the numerous threads on the subject, and the false interpretations.

Can you wash the crystalized white stuff away,
Water or HCl, somehow it doesn't look like silver chloride.

There is not enough information to give any advice.
What was the ore, what was done to the ore prior to leaching.
What leaching method was used. AR?
Details please.
And since you know you have Pd , what do the Assay say?
As far as I see there is no Silver, what it is I cant say, but the assay can explain that hopefully.

It is a bit dry. And yes, the foamy white stuff is what I believe to be silver chloride. I was able to separate some of the silver, because it seemed to develop last, but I still can't seem to separate it all.

First pulverized, wet; out of fear of Osmium tetroxide in dust. Then used magnet to separate iron. Then roasted. Then AR...

Silver Chloride will turn Grey in light, that is why it was used in films in the past.

And you have an assay that makes you expect Osmium?
Then you roast it??

 

[Yggdrasil]

It will not be Silver then, as Silver will not dissolve in any appreciate amounts in AR.

The ore is in chromite. Most of it is not effected by the AR.
The ore reeks of a chlorine smell.

It seems to develop after the AR, when in only HCL.

 

[Yggdrasil]

Any Chlorine containing liquid will not dissolve Silver as it will form a protective layer of Silver Chloride.

Okay. That explains why some that did have, some exposure to sunlight, appears to be turning grey-ish.

wow. okay, what would you suggest?

 

[Yggdrasil]

I think you need to set this aside and hope there is no Osmium or PGMs in there.
Osmium and Rhuthenium are exeedingly toxic and volatile as well.
The other PGMs are just exeedingly toxic.

So what did your Assay say??????

First you dare not grind it due to the volatile Osmium, then you roast the same volatile Osmium.
There are some glitches in this logic. Then you put it in AR.

So please again, what did the asssay say. (Not the XRF).

 

[Yggdrasil]

wow. okay, what would you suggest?

First what did the assay say. How much Silver is in there?

 

[TransitionM]

I did not have assay for silver, only PGMs, but numerous XRF readings indicate 15-17% silver.

So what kind of Assay do you have?
