Not anything about testing.
I just mention both supplying and testing labs avail locally are manipulating. Sorry I can not describe what I was saying
So since the local services are untrustworthy all international is?
So how do you get your ore again?
Have you tried roasting your gel?
If not roast it at a high temp.
About glowing red until a dry powder and try to dissolve this in HCl.
Mostly international companies provide poor grade service or just a misleading reports. The ore was attested from USA,
Gel is produced as HCl is added in fused ore. So roasting not become possible after gel production.
Pre Roasting works well for sulfides present, but not really affective on silicates.
Direct HCl after roasting is good but tests already done. Pressure and heat is required. I am searching for pressure vassels (not found yet)
At the moment, I am trying to saperate magnetic fraction after roast. But I want target silicates. So process can be shorten

Well there are many situation that can benefit from roasting.
I have not tried Silica gel but the gel that comes from Aluminum in HCl becomes a powdery residue that may be disdolved again.
The Tin residue from Nitric will also change so it is leachable with HCl.
Still in my opinion smelting is the route to go.
You have still not said what concentrations of PGMs you have.

I'm going to try again. In order to get good/helpful answers here it is necessary that we know what the starting material is. The reports you have are inconsistent with ANY ore I can envision. "Not mean metallic iron" - but at 87% what else, found in nature, could it be?The stuff has already been through some process to extract something - and leave iron - in what form we no not. The PM's you want to extract are in what forum? Your questions seem to indicate silicate, but you also mention sulfide. I think all this very strange.
Smelting is a way to go, no doubt. But I have to wait till a proper equipment supply of all required apparatus is not finalise.
Silica gel make it hard in seconds as HCl is added after naoh fusion.
Thinking to try boil with naoh, after that, smelt the residue, and see what go in solution.
Do not want mention openly the concentration. But the main elements are pt and rh that worth. with au pd ir and os.
Well you are the one that asks for help.
Help is easier if we have the whole picture, just saying.
The starting material is raw ore. Icp shows 89 percent iron.
The ore never been processed, only grinding and crushing. The stones are combination of sulfides and silicates. Where our values are. Some time high in sulfides and some time low in sulfides. Pgms are present are pd pt Rh os ir. Some time ruthenium presence is found.
Rest details, I do not want share.

If you have osmium be very very careful what you do , I believe that at one of the major refineries in South Africa if I remember correctly the technicians are only allowed to work in that department for one week and that’s it.
I know about osmium. Its low in percentage. But precautions are must.
You do not understand.
Not that kind of picture.
That phrase means, you tell us all we need to know to help you.
It is entirely possible all your neighbors or what not are out to scam you.
We are not and even not in a position to do so.
So either you tell us what the ore contain or help is hard to find.
Additionally Nick is correct, if it actually contain Osmium most refineries will not touch it.
Take care, it will blind you for ever, in an instant if you make a mistake.

I think I clearly inform about every metal present in ore
IF assay says 89 % iron, it was measured with XRF in my opinion. There are missing elements like alkali metals, calcium, sulfur, and mainly light elements like oxygen - if it is an ore.
There is simply not enough info to justify any meaningful answers in the moment, as smelting can be only justified from some content of values to pay for exorbitant gas/electricity/crucible/furnance maintenance fees. If PGMs aren´t following sulfides, that is another red flag for me. At least it would be strange.
In the industry, aside from very very rich ores with microscopic particles of rich sulfides or metals which cannot be separated from gangue, there is no other way of pre-concentration than gravity/flotation/cyanation-leaching in general. You need to reduce the bulk, and that is very expensive with smelting aproach. If you cannot make concentrate, that´s probably the end of the venture
And again, but very importantly, get together more info about that assay, as 89% iron is not possible in the ore. Find out what that assay measured, and what it didn´t. That is very important, what elements were omitted. In that case, it is irrelevant to calculate any meaningful PM contents, as you simply start with bad set of numbers.
I agree with Orvi we need more information , if you won’t or can’t elaborate about your material our help is coming to a very fast end…
Many time I see in reading, instead of to the point answer, users want fetch more info from other. Dissolving reducing silicate in an ore not require ores assay details, and especially it not required data pgms and their percentage. We'll have a look on it. May be it's helpful to get desired infoIF assay says 89 % iron, it was measured with XRF in my opinion. There are missing elements like alkali metals, calcium, sulfur, and mainly light elements like oxygen - if it is an ore.

There is no Si in there, so how does the Silicates form?
The information you share do not correspond to your description of your issues.
Is it wrong to assume you have not ore, but residues from an earlier process?
It was lump that I crush by myself .
Iron is in form of iron silicates.
Above mentioned results are not minirology.
One of our group member did try to dissolve iron to reduce iron content first.
After that they use a mathod of test that is , I am not satisfied with. But the results were as below.
