And then you go through a concentration step.
So the ores will come to the surface, they'll be less than 1%, definitely less than 5% concentration unless you have this world-class deposit.
And you'll typically go through a concentrating step.
So that can be mechanical, it can be thermal, it can be chemical.
And that gives you an intermediate product.
And those intermediate products kind of move all over the world and typically go to refining assets.
The refining operation effectively goes from anything that is like a 10% concentrate to a 50% intermediate product and turns into a high purity metal.
And then you go into a specialty chemical.
And so that's this intermediate product where you go through another chemical process to either make a metal sulfate or a metal hydroxide salt.
And then you will convert that into an engineered material, which is the next step.
And that, you know, in electrochemical systems and batteries, you'll have cathode materials, you'll have anode materials, and there the morphology and electrochemical performance in the system is really important.
And then you're ready to deploy into a battery cell.
And then you'll go into a module and then you'll go into a pack and then you'll go into a car or go into a stationary storage product.
And on the magnets side of things, you know, similarly, you'll get to a refined rare earth product.
And, you know, it's a long list of rare earths.
They often get bundled into like one group, but it's important to kind of like break them out.
And then the common way of making magnets, there's a few flow sheets, but you'll slurry it, you'll get the right blend of the different rare earths that you're trying to put in.
You'll cast that, you'll center it.
And then you'll go through a fairly intricate and like high precision machining process to get the geometry that you want with the tolerances that you need before you can deploy that into magnets and eventually into motors.
Yeah, it's very bespoke.
