Ways to get aluminum mid MV?

I'm close to getting MV energy hatches for my EBF and still struggling to get good amounts of aluminum going. My best option is probably mining a bunch of clay and electrolyzing it but it would be nice to passive it somehow. I tried centrifuging excess stone dust but it takes so long and consumes a ton of steam, I'm sure there are better ways. I've done some thaumcraft and bees if that helps
