Silicate ores

[Yggdrasil]

It was lump that I crush by myself .


Iron is in form of iron silicates.
Above mentioned results are not minirology.

Ergo samples can not be trusted.
You do not test lumps, crush and mix.
You need to read up on sample preparation and homogenous sample taking.
I suggest you read the book Fire assays by Bugbee.
You are very vulnerable for nugget effects here.

Sorry again, I said about lumps because many were assuming it's a residue of any process. That's why I mention that it's a clear ore that was in lump and I myself crushed it. So no chance of a residue after any prrocess
