Don't know if this is fixable from you side or not, but I found that iridite and naquitite from space exploration mod, the gange for them get added to the core mining recipe for normal core fragment crushing. It'd be great if this could be fixed since those resources shouldn't be so easily obtainable.

Hey, I'll try to look into that when I get some free time, in the meantime you could edit either mod and fiddle with adding dependencies to change mod loading order between those two and see if anything changes.

Sorry, fairly noob at modding. I want SE to load first so that the core mining stuff isn't effected at all, which dependency should be added to do that and how do I do that?

This mod modifies recipes loaded before it so you would want SE to load after which means you want to add this mod to the dependencies of SE, theoretically at least

That doesn't seem right. Wouldn't I want SE to load first so that the gange items aren't added to the core miner crusher recipes? I'll try it and see.

Fixed! Added SE as an optional dependency for this mod and it works great now. Old recipes for SE crusher are back.
Making the core miner give gange instead of the ore would be much more work though. I'd have to check for SE being added, then change the recipes for core fragment crushing (normal/uranium/iritite). Plus, I have Krastorio2 as well, so I'd have to do the same for rare metal too.
Since SE core mining recipes are determined when the mod loads, you can't really just replace the recipe whole. Otherwise an unknown mod might get excluded. The recipe would have to be modified as-is. recipe.product.remove("uranium-ore")/recipe.product.add("uranium-gange",1%). Something like that, though I don't know the exact coding for it since I'm super new to modding.

Created a branch with the added dependency: Link.

Will delete should you decide to update yours with the same dependency. Or some other fix.

Hey, updated, thanks for testing :)

Great! I changed my branch of the mod to deprecated. Not really sure how to actually delete...
