The fragment forge is your first step in turning ores into ingots.
Fragmenting ore blocks creates raw ores, and fragmenting raw ores creates ore dusts. When fragmenting ore blocks and raw ores, the fragment forge will output more than it is given. Occasionally, it will even provide additional ores of a different type.
Most addons affect the operation of the fragment forge. The machine yield addon will cause the fragment forge to produce additional byproducts.
