Right now this just uses the Alternating Splitters feeding into prepared Silos, you could use the -not yet in the game- Prioritizing Splitters, once the come out, but they would propably work the same like in this scenario, if they don't filter.

The Silos NEED to be prepared for this to work.

As an example I prepared the Output Silo1 like this:

(picture taken in update 0.3, works the same)

In this case I want to sort every kind of Carbon like this
But you can prepare the Silo as you please!
Remember: Every Slot of the Silo needs to be filled.

You can only transfer items into a Silo, if there is a avaliable slot for that item.
- this IS preferred by the conduits, empty Slots/Silos will be filled without sorting.
An avaliable slot would be either empty, or the stack for this item isn't full - this is used for sorting.
Thats why we prepare them like this:

(Pictures are made in Update 0.3, the sorting looked different back then)

The output silos need to be prepared, I did it like this:

^Output 1 is used for Carbon^

^Output 2 is used for Iron^

^Output 3 is used for Copper^

^Output 4 is used for Aluminium^

You can extend this pretty much indefinetely, in my save I need a S3-Silo for every common ressource an their variants, and it paid of not needing to rebuild once I had a lot of ressources.
If prepared and built correctly, anything put in the Input will either be sorted if possible, or stays in the Input Silo. This can stop the conduits from extracting the items and thus sorting/storing them, so remember to keep space avaliable.

To test this I put the following items in the Input Silo:


These are the Silos after sorting:

Carbon

Iron

Copper

Aluminium

These Items wouln't be sorted this way.

This is what my System for sorting every Ressource looks like.

From left to right I sorted:
Carbon, Iron, Copper, Aluminium, Silicon, Gold, Chlorine, Sodium, Tantal, Niobium, Titanium, Wolframite, Strontium, Phosphor an Lithium.
The bottom row of Silos are Raw Ressources, the middle row are Refined and the top row are Purified Ressources.

I hope you could understand me and - more importantly - the Guide well enough (English isn't my first language, please have mercy)
If there are any uncertainties, please comment on the guide!
