I never use TechReborn, but I always hate having so much Galena and Bauxite in my sorting system with nothing to do with it.
I mean Bauxite is kinda useable as it is ore dictionary with IE bauxite, and you can drop it into an ordictionificator to get aluminum, but they both just seem like a wasted resource to anyone who never goes into tech reborn.

Ideas could be using the dust in crafting recipes or making it somehow be smelted into other metals

This is no longer relevant as we've moved to IE bauxies/alumionum as the primary worldgen for aluminum.

There COULD be more to do with aluminum/bauxite etc but the issue was originally created becasue bauxite and galena ore were in worldgen (they are not now) and had excess resources from processing them

aluminum is a specific thing I'd like to address, and wouldn't mind maybe making something minor to do with the galena as well.
