It adds at lot of things that can work as a backbone for other mods. The ores are there but need to be added by other mods to spawn if you don't have them spawn on Nauvis.
Regardless, you should still be able to build the new buildings - but not all will be able to be utilized to their fullest extent with the ores. Like some chemistry recipes can be done in the dangerous cryogenic plant. Yet the froth floatation plant won't be useful.
You should be able to use the new recipes to make carbon to make blast fuel for the new furnace too, and make dilute sulfuric acid to do saponification to make glycerol, fatty acids, and plastic and carbon from those recipes.
TLDR: New ways for carbon and plastic.
