The underlying goal is to figure out the optimal process for producing specific combinations of raw ores, especially since I didn't realize it was possible to get pure ore for things other than Fe/Cu.

Check out my spreadsheets! Same raw data as these flowcharts, but I'm more focused on ...

My mistake! Exasperation is right; crushers' speeds range from 1.5 to 3. In fact, it seems each refinery building type behaves differently with speed.

Yellow belt speed: 13.33/sec
Red belt speed: 26.66/sec
Blue belt speed: 40/sec

Crusher base speed: 2/sec
Crusher multipliers: Mk1=1.5, Mk2=2.0, Mk3 ...

All your ratios are correct so far, steinio!

crusher : floatation = 1:4
hydro : floatation = 1:4
floatation : chem refinery = 1 : 1 (next step)

If you want your red belt to be 100% consumed by Mk1 equipment, you'll have to up the production capacity, but I'm sure you are planning for the Mk3 ...

This is my basic analysis of ore throughput.

Hopefully it gives insight into how efficient each refining stage is, which facilities you need to build, and what to do with all the slag/stone/gems.

This is fantastic! I've been trying to model Angels Ores in spreadsheet form, but it gets a bit messy as soon as I deviated from the refining/sorting line. Your flowcharts are better.

One inaccuracy I noticed is your depiction of combo (catalytic) sorting.
