Bauxite ore from other mods can't be used in the industrial grinder and vice versa, bauxite from TechReborn isn't recognized by others. Maybe this is caused by different "Aluminium" spellings in the oredict?

yeah, that might be why

I think the most common spelling is Aluminium, based on what i saw at other mods

It's surely due to the fact that Bauxite is Aluminium for other mods while it's Titanium in TechReborn.

Suggestion is to finish the recipe to either use the centrifuge or electrolyzer. Aluminium (Al)[http://www.chemicalelements.com/elements/al.html] is not an easy thing to get and it should take several machines to get it.

Yep, something like this: https://en.wikipedia.org/wiki/Bayer_process
At least the crystallization part.

Like venturaguy101 said there needs to be a use for bauxite dust. Especially because you can process the ore in machines from other mods but that leaves you with dust that has no use and no small piles of titanium.

im thinking something to create aluminum is going to be the best plan.

Yeah I am slowly going through all the recipes to make sure they're all right. Going to be doing centrifuge/electrolyzer ones next which should fix this

Bauxite dust will no longer be useless in the next release. not sure when that'll be though. I don't know about compat though.

Closing this as I dont feel like there is a solid solution to this. I have spoken to devs of other mods with Bauxite and we didnt come to a solution.
