Non-Assayable Ores

[Yggdrasil]

That will be worth to try. I am having some issue for flux, as it need too too much basic flux to become liqued. And very high heat. I am having problem to have any pot or I am thinking to look for induction. But again induction need something that stay with such highly acidic ore.

You talk about a video. Can I have the link

You need to use a proper Crucible and tune your flux to the ore.
Add some Fluorspar or Cryolite to thin the flux.

When you get your Iron you don’t need much flux, just a slag cover and start blowing Oxygen into the molten metal.

Do some research on sparging.

I have no link.
It was a program on TV years ago.

How I can oxidise iron from iron bars?

Let me see on this. It's really helpful.

Thanks alot man, you really open some lines of written process for me.

I have two main issues.
1 , tests shows silver and rhodium present , when we process/smelt, bars or acids not show any of both. But slag shows silver and rh. We resmelt/redissolve slag, same results. Values still in slag. What's the problem could be.(While rest values are enough but Rh has good quantity, worth to recover)

Second, I read somewhere of sparging the melt with jet water to break iron in pieces. It was reletive to ore processing. But yet can not understand it's mathod to oxidise iron. It says it works to properly mix the molten metals. I can not understand

You can not sparge with liquid as the definition is pumping a gas through a molten media.
How did you measure the slag? ICP?

The Oxygen sparging is when you pump pure air or Oxygen into the bottom of the molten metal through a tube.
The Oxygen will then combine with the Iron and form Iron Oxide which floats to the top and goes into the slag.

Yes all the test that are done after melt, are ICP.

Which grade iron should I use as collecter. Because I come to know , the iron I am using as collecter is full of carbon and magnese and silicon. (Cast iron)

Now I'm confused.
You did not say you added Iron.
Your ore have enough Iron in it to act as collector don't it?
Just make sure you have enough Carbon in it so it is reduced.

Any way you do it it needs to be milled quite fine and homogeneous before smelting.
Add all the ore and flux in a ball mill and let it run til it is smooth and fine.
Then you can move it to the crucible.
