Plus, if you got a couple of maxed-out tile accelerators from ChromatiCraft, you can speed up those processes to obscene degrees. Especially with Mekanism machines. Ever seen a fully decked-out elite smelting factory with a 256x accelerator on it? It blazes through dust like nobody's business.If simply acquiring ingots was your only goal in the game and you spend all your time on that goal, then simply building BR reactors, setting down Quarry+/Ender Quarries and running it through something like RoC/Mekanism ore x5 should get you there in short time.
Or there is a million cross mod exploits you can take advantage of in most packs to speed it up.
