Infernal Furnace + Native Ore Clusters vs Pulverizer (FTB Ultimate)
(Igneous Extruder > Cobble > Pulverizer > Sand > Smelter) This process of re-smelting the ingots with rich slag after pulverizing them also gives you quite a lot of Rockwool, which you can use to build colored structures that are blast resistant and non-burning. Very nice.
